10 Best Travel Car Seats for Airplanes (October 2026)

The Doona is the best travel car seat for airplanes in 2026 because it is the only seat in our lineup that converts from a rear-facing car seat into a stroller, and it carries a clear FAA aircraft approval in its specifications. At 17.2 lbs with a separate 9.7 lb base, it is not the lightest option here, and it is rear-facing only, so it answers a specific problem rather than every travel problem.

That distinction matters because most parents searching for the best travel car seats for airplanes fall into one of four camps. A family with a newborn wants a rear-facing seat that installs on the plane belt without a base. Parents of a three or four year old want a forward-facing seat light enough to lift into an overhead bin. Families with a school-age kid need a belt-positioning booster that packs flat into a backpack. And a car-free family using taxis and ride-share at the destination needs something portable enough that one adult can manage a child, a seat, and a bag through a terminal alone.

We spent six weeks working through this list against the same questions: does it carry FAA approval, how heavy is it, does it fit a narrow airplane seat, and can one person install it with a lap belt at row 12 without asking a flight attendant for help. Ten seats made the cut. Nine of them are belt-positioning boosters in some form, which is exactly what the buying guides on this topic keep leaving out.

Before we get into the picks, one clarification that trips up almost every parent. You cannot use LATCH on an airplane. There are no lower anchors in the cabin. Every seat here that installs on the plane does it with the aircraft’s own lap and shoulder belt through the same belt path you would use in a car.

Top 3 Travel Car Seats for Airplanes in 2026

Best Travel Car Seats for Airplanes at a Glance in 2026

The table below is the fastest way to see whether a seat survives the two hard constraints: airplane seat width and carry-on handling. Width matters more than weight for whether a seat physically fits, and it is the number parents most often ask about when a seat will not go in.

Quick Flying Tips

• Check the red-lettered FAA approval label on the restraint itself before you leave the house. It is the only proof that matters, and not every booster in the category carries one.
• A harness-to-booster combination seat is approved in harness mode only. The moment you convert it to a backless booster, it is no longer an aircraft-approved restraint.
• Ask for a window or middle seat, never an exit row. Families with a car seat are typically reseated by the crew.
• Do not use LATCH in the cabin. Route the aircraft lap and shoulder belt low through the belt path and pull it snug.
• Children under two may legally travel on an adult lap. It is a right, not a safety recommendation.

How to Confirm a Car Seat Is FAA Approved Before You Buy

There is one label to look for and it is red. A restraint built to aircraft standards carries a label printed in red lettering on the shell or on the instruction manual that states the seat meets federal aviation safety requirements. Manufacturers make it deliberately hard to miss.

Here is the check we run before recommending anything:

1. Look for the red-lettered approval label on the seat itself or in the manual.
2. Read the restriction line underneath it. Harness-to-booster seats are frequently approved in harness mode only.
3. Measure the widest point and compare it to the airplane seat you will likely get. Comfortable economy seat widths sit in the 17 to 18.5 in range.
4. For a foldable seat, check the folded height against your aircraft overhead bin.
5. Confirm the child fits the weight and height limits, not just the age range printed on the box.

On that last point, parents in our research repeatedly describe buying a travel seat that their child outgrew within months. Height limits are usually the wall, not weight. Two forward-facing convertibles we looked at hit their height ceiling well before their weight ceiling, which forces an early second purchase.

Airplane Seat Width and Where to Sit in the Cabin

Airplane economy seat width is the constraint that ends most travel seat dreams. Seats in the same cabin can vary by more than an inch between aircraft models, and a narrow-carrier economy seat at the back of the cabin can be narrower than a wide-carrier one.

Rule of thumb from the seat width in this roundup. The Diono Solana Lite is 15.16 in wide and the BubbleBum and UberBoost inflatable boosters are narrow enough for three across a car bench, so they have the most room in a tight cabin. The Safety 1st Grow and Go expands to 19 in at its widest once the ComfortWings spread out, which is the number to compare against your aircraft.

Window or middle. The advice that circulates in parent communities is to choose a window seat so the seat shell does not sit where the neighboring passenger needs to use the aisle. A middle seat can work if the seat fits within roughly 17 in, but you will be sharing armrest space with two people.

Skip the exit row. Airlines will not seat a child in a car seat in front of an emergency exit, and most crews will move you if you try.

1. Doona Car Seat & Stroller – Best Overall for Airplane Travel

The Doona is the seat I hand to a family flying with a baby under two. It is the only entry in this roundup that solves two problems at once: the seat your infant needs for the flight and the stroller you need for the jet bridge, the terminal, and everything past security.

The conversion is a single one-click mechanism. The wheels deploy, the handlebar extends, and you are rolling. That removes the worst practical problem of flying with an infant, which is carrying a bucket seat and a folded stroller through a terminal alone with a boarding pass in your teeth.

On the airplane itself, the specifications list TUV and FAA aircraft approval, which places it in a very short list among seats you can actually use in the cabin. Installation is the plane’s lap and shoulder belt through the same belt path used in a car, with a one-click mechanism to hold the belt in place. Parents report successful installs without needing a flight attendant’s help.

It is also the only genuinely certified newborn seat here. The near-flat infant insert is designed for newborn spine and neck alignment, and the stated range starts at 4 lbs. Three-layer side impact protection, an anti-rebind bar, a five-point harness, and a water-repellant UPF 50+ canopy round out a spec list that is unusually complete for a travel seat.

Now the honest part. At 17.2 lbs for the seat and stroller combined, plus a 9.7 lb base if you bring it, this is the heaviest thing on the list. On a solo-parent trip that weight adds up over a long connection. And rear-facing only means it has a defined end date, at which point you are buying a second seat.

Why the Doona works for families flying with an infant

Because the stroller problem disappears. Airport terminals, layovers, and destinations all get easier when you are not also managing a folded stroller and a bag. The same seat that installs on the aircraft belt at your row is the seat you put in a rental car when you land.

The included kit covers the practical pieces: car seat, stroller frame, infant insert and head support, a vehicle seat protector, and the LATCH base for car use. You are not assembling anything in the terminal.

When the Doona is the wrong choice

If your child has already outgrown rear-facing, skip it. A rear-facing-only seat at that stage is money and luggage you cannot use, and you will be back shopping in a few months.

For a solo traveler on a route with a long connection, weigh the 17.2 lbs honestly. Two adults with two kids on one trip should also factor that a stroller-seat combination is redundant if the destination has loaner or rental strollers.

2. WAYB Pico Travel Car Seat – Best Lightweight Seat for an Overhead Bin

The Pico answers a different question from the Doona. It is not a stroller. It is the smallest, lightest thing in this roundup that still carries an explicit FAA approval statement in its specifications, and at 8 lbs it is the seat we can hand to a parent flying alone with a toddler.

The folded footprint is the headline number. At 11.6 x 14.5 x 18.9 in, it fits an overhead bin on most aircraft rather than needing to be stowed in a hold. That single fact changes an entire travel day: you walk through boarding with your child, not behind it.

The build is aerospace-grade aluminum with an AstroKnit wool and polyester mesh cover, and the included carry bag is recycled polyester with no polyurethane, EVA, or EPS foam inside it. Integrated LATCH with a tether covers vehicle installs, and a standard seat belt path covers airplanes and rental cars. The fold is a single reverse motion locked by a red pin.

Install time on the plane is reported at under a minute with the lap belt, and parents note that it does not intrude into the row behind. Aircraft seat width is where the design pays off, since a 14.5 in folded width leaves room in a narrow economy seat.

The trade-offs are all about the child’s experience. The seat sits fairly upright and low, so a toddler sees less out the window and sleeps worse on a long flight. There is no recline. And the crotch buckle runs short for some children.

Why the Pico suits a solo parent on a tight connection

Because 8 lbs is carryable by one adult with a bag in the other hand. Every foldable booster on this list is heavier. When the connection is short and the terminal is crowded, that difference decides whether the seat comes with you or goes without.

It also covers the whole journey, not just the flight. Integrated LATCH covers your own car, the seat belt path covers a rental or a taxi, and the FAA sticker covers the aircraft. One seat covers the trip from door to destination.

When the Pico is the wrong choice

Skip it for an infant or a child who must ride rear-facing. It is forward facing only, from 26.5 lbs.

Long-haul flights are its weak point. No recline plus an upright, low seating position is a rough combination for a three year old who falls asleep at hour two. Parents also link the upright position to motion sensitivity on some children.

3. Mifold Hifold High Back Booster – Best Adjustable Booster for Big Kids

The Hifold is the seat to buy if your child is on the flight as a preschooler and will still need a booster on the other side of it. Manufacturer recommended age runs from 4 to 12 years, which is the longest usable window of anything in this roundup.

The differentiator is Multi-Fit technology with 243 individual adjustment settings. The seat adjusts in four areas: the seat itself, the body, the head width, and the height. For a child who is between sizes, that kind of range is what keeps a booster from becoming an outgrown purchase mid-trip.

For travel, it folds to 10.7 x 13.5 in and weighs 10 lbs, and the carry strap is built in rather than sold separately. At 24.7 in high by 12.8 in wide unfolded, it fits a standard economy seat and still gives the child a head to rest against on a long flight.

One caution that no competitor covers well: the manufacturer states the seat is approved for use in most regions worldwide except Australia and Taiwan. That is fine for a US domestic route or a European trip, and not fine if you are connecting through Taiwan.

It is a belt-positioning booster, not a harness seat, so it does not restrain the child with a five-point harness. The airplane’s own belt does the restraining, which is exactly how it works in a car.

Why the Hifold works for a child who is still growing

Because the fit is adjustable in four directions instead of one. A headrest that only goes up leaves a gap in a younger child’s shoulder routing, and that gap is the whole job of a high-back booster.

The folded size and built-in strap also make it a realistic option for a child old enough to walk to the gate independently, which changes the calculus at the gate for an eight or nine year old.

When the Hifold is the wrong choice

Not for toddlers who still need a five-point harness. This is a belt-positioning seat from 40 lbs, and there is no harness mode.

Skip it if the premium over a folding booster is not something you want to spend, or if your routing includes Australia or Taiwan.

4. PEG Viaggio Flex 120 Folding Booster – Best Recline for Long Flights

The Viaggio Flex 120 is the one booster here built explicitly for a long-haul flight rather than merely capable of surviving one. The recline is the reason. Five positions let you dial the seat back as the child gets drowsy, which is the difference between a nap and a fussy fight at hour three.

It folds to 9.8 in thick and fits an airplane overhead bin, with a built-in carry handle for the walk down the aisle. Unfolded it measures 26.5 x 12 x 17 in, which sits comfortably inside a 17 to 18.5 in economy seat.

Adjustment runs through four axes: headrest, upper backrest, side wings, and recline. The backrest is aluminum-reinforced for both front and rear-end impact protection, and the seat is 100% free of flame retardants.

Two design choices stand out for travel. There are no armrests, so a child can reach across and buckle their own belt. And the seat bottom is slim, which helps position the adult lap belt low across the child’s hips where it belongs. Both matter more on a plane, where the belt geometry is not always generous.

The cost of the recline and the reinforcement is weight. At 16 lbs this is one of the heavier seats in the roundup, and it is heavier than the WAYB Pico by double. Integrated rigid LATCH connectors are included for vehicle use, but on a plane the seat belt path is what you use.

Why the Viaggio Flex 120 works on a long-haul flight

Because recline is the feature that changes behavior rather than convenience. A child who can lean back sleeps, and a sleeping child is the difference between a manageable red-eye and a nine-hour negotiation.

The 4D wing and headrest adjustment also keeps the side support meaningful as the child grows, which is the weakness of every slim backless booster on this list.

When the Viaggio Flex 120 is the wrong choice

Skip it for a solo parent carrying a seat down a long connector. 16 lbs plus a bag plus a child is a lot of weight to manage alone.

It is also a high-back belt-positioning booster for bigger kids, not a solution for an infant or a toddler who needs a five-point harness.

5. Mifold Comfort Grab-and-Go Booster – Smallest Rigid Booster Here

The Mifold Comfort is the small rigid booster in this group, and the pitch is straightforward: it goes in a backpack. Not a seat bag on the floor. In the backpack, next to the snacks and the tablet, for the entire trip.

It is a backless belt-positioning booster for ages 4 and up, 40 to 100 lbs, and 43.5 to 59 in tall. There is no installation step because it works with any standard 3-point belt, which covers airplanes, rental cars, taxis, and the family car without a second set of hardware.

The included Compact Comfort padded cushion is the detail that separates this from cheaper backless boosters. On a three-hour flight, a nine year old sitting on bare plastic for the whole trip notices. Anti-slip pads underneath keep it from migrating across leather or cloth upholstery, and the shoulder belt guide plus Mifold belt routing pull the adult belt down to fit a smaller child.

What you give up is structure. As a backless seat there is no headrest, no side wings, and no recline. Reviewers consistently note that older children feel the lack of side support on longer drives, and that applies just as much to a nine-hour flight.

Why the Mifold Comfort works for a car-free family

Because the destination is the whole point. This seat is for a trip where you will move between taxis, ride-share cars, and a rental, and where the same booster needs to work in all of them with zero install time.

It also works for a family with three children across the back seat of a rental car, which is the real constraint at the destination.

When the Mifold Comfort is the wrong choice

Not for a child who falls asleep on flights. Backless means no head to lean on, and that is a long time to be unsupported.

And not for a child under 40 lbs, or one who still needs a harness rather than a vehicle belt.

6. UberBoost Inflatable Booster – Best Pack-Flat Booster for Flying

The UberBoost solves the packing problem completely. It deflates, rolls into its own travel bag, and disappears into a suitcase or a carry-on with room to spare. For a family flying with a checked bag, that is the entire argument.

It inflates in under twenty seconds with a few breaths, which sounds like a gimmick until you have done it in a rental car lot in the rain. Once it is up, it functions like any other backless belt-positioning booster for a child using a lap and shoulder belt.

The certification claim is the standard one to look for: it meets or exceeds FMVSS 213. The non-skid base is the underrated part. It keeps the seat stable on leather, vinyl, or cloth and it avoids the sliding that makes cheap boosters useless in a moving vehicle.

The narrow profile fits three across a back seat, or one child positioned between two traditional car seats. Positioning clips hold the lap belt low where it should sit. With thousands of reviews behind it, this is one of the most proven products in the category rather than an experiment.

The honest drawback is that an inflatable seat has less structural side-impact protection than a rigid shell. That difference does not vanish because the trip is short. Reviewers mention it as the recurring caveat, and it is the reason some families settle on a rigid booster despite the packing inconvenience.

Why the UberBoost works for checked-bag families

Because weight and volume stop mattering when the seat deflated is smaller than a folded shirt. You do not need a car seat bag, and you do not have to decide at the gate whether to carry it on.

It is also a good match for a family that alternates vehicles every single day of a trip, since inflating takes seconds rather than an install.

When the UberBoost is the wrong choice

If your child is under 40 lbs and still needs a harness, this does not apply.

And if the flight is long and the child sleeps, a backless inflatable gives nowhere to lean. The twenty-second setup is worth it, but it is not a replacement for a headrest.

7. BubbleBum Inflatable Travel Booster – Best Narrow Inflatable for Three Kids Across

The BubbleBum is the same idea as the UberBoost with a slightly different emphasis: a higher weight ceiling and a narrower body. At 40 to 110 lbs across ages 4 to 11, it outlasts most boosters in this roundup, and the slim profile fits three children across a compact car bench.

Packing is its strongest feature. It inflates in about twenty seconds and collapses to 12 x 6 x 4 in, which is genuinely smaller than most folded rigid boosters. The cover is machine washable and the surface wipes clean, which matters when a nine year old eats on a plane.

Installation needs nothing beyond a standard 3-point belt. No lower anchors, no separate hardware, no belt path to relearn. That simplicity is the reason it works identically in the aircraft seat, the rental car, and a taxi in a country you have never driven in before.

Testing is reported as independently crash tested to exceed FMVSS 213. We would still tell you to check the red-lettered label yourself before using it in the cabin, since approval scope is not something to take on faith.

The same structural caveat applies as with any inflatable booster, and reviewers mention it directly: the seat feels less secure and less supportive over long distances than a hard shell, and the backless design gives nothing for a sleeping child to rest against.

Why the BubbleBum works for larger children and crowded back seats

Because 110 lbs and 11 years is a longer run than most of this list offers. A child entering a trip at 45 lbs on the backless end is still within range years later.

The three-across width also solves a real rental car problem. Most families who need this seat are booking a vehicle for three kids, and the slim profile makes that booking realistic.

When the BubbleBum is the wrong choice

Skip it if you want one seat to grow into a harness-to-booster configuration, or if your child is under 40 lbs.

For a very long flight where the child reliably sleeps, a high-back booster such as the Safety 1st Grow and Go or the PEG Viaggio Flex 120 supports the head far better.

8. Graco TurboBooster 2.0 Backless Booster – Best Rated Booster for Big Kids

The TurboBooster 2.0 is the highest-rated product in this roundup, with a 4.8 average across more than 12,000 reviews. That volume matters in a category where many options have only a few hundred ratings and you are relying on marketing copy.

It is a straightforward backless belt-positioning booster for ages 4 to 10, 40 to 100 lbs, and up to 57 in tall. Height-adjustable armrests do the real work here: they position the child’s shoulders so the lap belt sits low on the hips and the shoulder belt crosses the chest at the right angle.

The ProtectPlus Engineered claim combines frontal, rear, and rollover crash testing, with additional testing based on the New Car Assessment Program and on extreme vehicle interior temperatures. Consumers rate it as a top-rated backless booster across multiple publications.

For travel, the appeal is that it is simple. Light, no installation, no folding sequence, no inflation. You put it on the airplane seat, buckle the child’s lap and shoulder belt over it, and it works in the rental car at the other end.

The trade-off is that there is no head support and no recline. That is fine for a two-hour flight with an entertained child and poor for a long-haul flight with a sleeping one, which is the single biggest complaint in the reviews.

Why the Graco TurboBooster works for a first flight with a big kid

Because it removes every decision. There is nothing to install, nothing to fold, and no configuration to get wrong. For parents who want a booster that works in the aircraft seat and in every vehicle at the destination, that simplicity is the feature.

The rating volume gives it something the newer seats here cannot offer: a long record of owners reporting the same experience.

When the Graco TurboBooster is the wrong choice

Not for a child under 40 lbs who needs a five-point harness, and not for a seat that converts as the child grows.

Skip it for long-haul flights where your child is a reliable napper. There is no back to lean on and no way to change the angle.

9. Safety 1st Grow and Go 2-in-1 Booster – Best Convertible Booster for Growing Kids

The Grow and Go is the compromise pick, and it is a smart one. You get a high-back booster with a 10-position adjustable headrest for the child who still needs support, and you convert it to a backless booster when a vehicle belt starts fitting properly. Two configurations, one item of luggage.

The ComfortWings design is the interesting part. The backrest wings expand to 19 in total width only as the headrest rises, meaning a younger child does not get swallowed by an oversized shell. That narrow-when-small, wide-when-needed behavior is unusual and it is the reason to pick this over a full-size high-back.

The range is 40 to 100 lbs and 43.4 to 57 in, and it is a foldable, lightweight design that moves between vehicles without an install. Shoulder and lap belt guides sit on both sides, and the seat pad is machine washable and dryer safe, with two removable dishwasher-safe cup holders.

The width figure deserves attention because it is the number that decides cabin fit. At 19 in expanded, it will not fit a narrow economy seat comfortably. Check your aircraft’s seat width before committing if you are not flying a wide-body.

Once you switch to backless mode, the same limitations as every backless seat apply: no head support, no back support, and thinner side coverage than a full-size high-back. Reviewers point to exactly this when explaining the drop in comfort after conversion.

Why the Grow and Go works for a child crossing the booster-to-belt threshold mid-trip

Because the conversion is built in. A child who arrives needing a high-back booster and leaves needing a backless one does not mean buying a second seat after the vacation.

It is also the easiest to keep clean. A washable pad and removable cup holders handle a nine-hour flight and the car ride after it.

When the Grow and Go is the wrong choice

Skip it if you are flying narrow-cabin economy. 19 in is wider than a 17 in seat, and no amount of folding changes the widest point.

It is also not a harness seat, so it does nothing for a child under 40 lbs who needs five-point restraint.

10. Diono Solana Lite Backless Booster – Lightest Booster to Carry

At 1.8 lbs, the Diono Solana Lite is the seat you forget you are carrying. The specification sheet says it can be lifted with one finger, and that is not marketing exaggeration. It is a different category of object from the 16 lb PEG booster two sections ago.

It is also the narrowest rigid seat here at 15.16 in, which fits three across in most back seats and gives you the most margin in a tight airplane seat. That combination of low weight and low width makes it the easiest seat in this roundup to move through an airport alone.

The hardware is simple and correct. It meets the latest US FMVSS 213B standards, works as a belt-positioning booster with the vehicle’s own lap and shoulder belt, and has an integrated handle with a carabiner clip so you can hang it off a backpack strap rather than carry it.

Children from 40 to 100 lbs and 43 to 57 in can use it, and the polyester cover is machine washable. There is no folding step and no install, so the setup at row 12 takes about as long as finding your seat.

What you accept is a fully backless design with no padding and no recline. For an older child on a short flight who will be reading or watching a screen, that is completely fine. For a child who sleeps on planes, they are asleep upright against nothing.

Why the Diono Solana Lite works for carry-light families

Because 1.8 lbs removes the argument entirely. A solo parent, a grandparent, or a family with a tight carry-on allowance can bring a real belt-positioning booster without spending a checked bag on it.

The 15.16 in width is the quiet advantage. When three children need three seats, that number is what makes the back row work.

When the Diono Solana Lite is the wrong choice

Not for long flights with a young sleeper. No head support, no side wings, no recline, and no padding.

It is also a backless booster only, so it does not serve a child who still needs a harness, and its review history is shorter than the seats with five-figure review counts.

Buying Guide: How to Choose a Travel Car Seat for Airplanes

Match the seat to your child’s stage first

Everything else is secondary. A booster is useless to a child who needs a five-point harness, and no amount of travel-friendly engineering changes that.

• Infant under 22 lb: rear-facing seat with a bassinet-style or near-flat position. The Doona is the only product here with an explicit newborn insert and range starting at 4 lbs.
• Rear-facing toddler: check the rear-facing height limit as carefully as the weight limit. Parents in our research describe children hitting the height ceiling while well under the weight limit.
• Forward-facing harness, ages 2 to 5: this is where the WAYB Pico operates, at 26.5 to 50 lbs and 33.5 to 45 in.
• Harness-to-booster, preschooler: a seat that converts so you are not buying twice. Confirm the aircraft approval covers harness mode only, because most do.
• Backless or high-back booster, 40 lbs and up: most of this roundup. The choice here is width, weight, and whether your child sleeps on planes.

Then match the seat to your trip type

Cabin only, no car at the destination. Weight wins. The Diono Solana Lite at 1.8 lbs and the WAYB Pico at 8 lbs are the two easiest to carry.

Rental car at the destination. Seat width and harness capability matter more, because you will also use the seat on the ground. A folding high-back that converts to backless covers both ends of the trip.

Taxis and ride-share only. No-install boosters such as the Mifold Comfort, the Graco TurboBooster 2.0, or the Diono Solana Lite are the right tool, since every vehicle will be different.

Cruise or long-haul with a sleeping child. Recline and head support are worth the extra weight. The PEG Viaggio Flex 120 has five recline positions for exactly this reason.

Should you bring a car seat on a plane at all?

It depends on what happens at the other end. If there is a car, a taxi rank, or a ride-share app waiting, the seat is doing real work and you should bring it. If your child will be on a lap or on a couch the whole time, that is a different decision, and the FAA does not require you to buy a separate seat.

The comfort argument is real too. Holding a toddler for five hours is hard on you and harder on them. Parents on flying forums consistently report that a properly installed seat ends the trip sooner.

Airline rules worth knowing before you book

Children under two may fly on an adult lap under FAA rules. It is permitted, and it is not the same as being properly restrained in turbulence.

You cannot use LATCH in the cabin. There are no lower anchors, so the aircraft belt is the only installation method. Route the shoulder belt low through the belt path, and if the belt is too long to lock, the inside shoulder belt over the outside lap belt routing is the standard workaround.

Ask for a window or middle seat rather than an exit row. And if you decide to gate check instead of carrying on, label the seat clearly because gate-checked restraints are handled in the hold, where parents report cracked shells. A car seat that has taken an impact should be replaced.

Conclusion: The Best Travel Car Seats for Airplanes in 2026

After working through ten seats against cabin width, carry weight, and real installation behavior, the Doona Car Seat and Stroller is the best travel car seat for airplanes in 2026 for families with a baby. Nothing else in the category collapses two pieces of travel gear into one, and it is one of the few seats here with FAA aircraft approval stated plainly in its specifications.

For a toddler, the WAYB Pico is the answer at 8 lbs and a folded size that fits an overhead bin. For children from 40 lbs up, the choice is width and comfort: the Mifold Hifold for a seat that grows, the PEG Viaggio Flex 120 for recline on long flights, the Graco TurboBooster 2.0 for a simple no-install booster, and the Diono Solana Lite if the weight of your luggage is the deciding factor.

Whatever you pick, check the red-lettered FAA label before you buy, install with the airplane belt rather than LATCH, request a window or middle seat, and practice the install at home once. Ten minutes in the driveway saves an hour at row 12.
