Lightweight Car Seats for Air Travel
The Cosco Scenera NEXT is the default budget seat for flying: 6.8 lb, $59, certified for use on an aircraft, 17 inches wide, and harnessing a child from 5 to 40 lb. For a baby alone, the Evenflo NurtureMax infant carrier is lighter still at 6 lb and $74.99, though it tops out at 22 lb.
The ten products split first on whether they can be used on the plane. Six are approved for the aircraft seat, the Cosco Finale is approved in harness mode only, and the three boosters are not, because a booster needs a shoulder belt and airplane seats have lap belts. Those boosters are for the car at the other end. The second split is money: the WAYB Pico and the Cosco Finale both weigh 8 lb, and one costs $499 while the other costs $49.97.
Our picks
- Lightest seat from newborn through toddler: Cosco Scenera NEXT. A 6.8 lb convertible rated from 5 to 40 lb and 43 inches, certified for aircraft use, for $59.

Which seats you can use in the airplane seat
Only the harnessed seats go on the plane. The Scenera NEXT, the three infant carriers and the WAYB Pico are all approved for aircraft use, and so is the Evenflo Tribute LX, a 9.4 lb convertible that covers the same 5 to 40 lb range as the Scenera NEXT for about forty dollars more. The Cosco Finale flies in harness mode and converts to a booster once you land.
One caution on the Yes column: Evenflo's own pages don't state aircraft certification for either the Tribute LX or the NurtureMax. Before flying with either one, check the label on the seat itself.
Light enough to carry, big enough to keep using
Among the harnessed seats, the lightest tend to be the ones children outgrow first. The NurtureMax stops at 22 lb and 29 inches, so it suits one big trip in the first year. The Nuna and the Doona take a baby to 30 lb, and the Scenera NEXT and Tribute LX to 40 lb. The WAYB Pico reaches 50 lb and 45 inches but doesn't start until 26.5 lb, so it is no use for a baby.
Height usually runs out before weight, which makes Max Child Height the column to check against your child today. The Finale's harness reaches 49 inches, the most of any seat you can use on the plane.
Boosters for the rental car
All three boosters cover 40 to 100 lb and 59 inches, so the choice is packing space against support. The BubbleBum inflates, weighs 1.1 lb, costs $40 and is narrow enough to fit three across most back seats. The mifold Comfort folds to about the size of a large paperback at 1.75 lb. The mifold hifold gives head and torso support that neither backless seat can, and it asks more in the carry and at checkout than either backless seat: 10 lb and $219.99.
The options in detail
Evenflo NurtureMax Infant Car Seat
The cheapest infant seat here and one of the lightest, at just under 6 lb for the carrier, which Evenflo calls the lightest in its class. The low 4 to 22 lb range makes it a true newborn seat that most babies outgrow faster than a 30 or 35 lb carrier, so it suits one big trip in the first year rather than three. A good pick if you are flying with a small baby and would rather not spend much on gear you will retire quickly. Evenflo does not state aircraft certification on the product page, so check the label on the seat itself before you fly.
Nuna PIPA aire rx
The lightest infant carrier in this table at 6.2 lb without the canopy and inserts, and the only one whose maker spells out that it is certified for aircraft use with or without its base. That distinction matters in practice, because you install an infant seat on a plane using the aircraft belt, with the base left at home or checked. This is the premium end of the market and the price says so. Nuna sells it bundled with the PIPA RELX base, and its own site showed colourways out of stock while this table was being built.
Doona Car Seat & Stroller
An infant car seat whose wheels fold out into a stroller, which is why parents fly with it in spite of the weight: you roll it through the terminal, down the jet bridge and straight into the aircraft seat with no separate stroller to gate check. At 17.2 lb it is by far the heaviest thing in this table, and carrying it up an aisle or a flight of stairs is the compromise you are making. It is rated only to 30 lb and 32 inches, so it is a first-year purchase. FAA approved for use on the aircraft.
Cosco Scenera NEXT
The default budget travel car seat, and at 6.8 lb the lightest convertible in this table. It is 17 inches wide, which is the reason it fits airline seats that wider convertibles fight with, and it is cheap enough that plenty of families buy one purely for trips and leave their good seat at home. Certified for use on an aircraft. The trade-off is that it is bare bones: thin padding, a 40 lb harness limit, and a fit most children outgrow rear facing somewhere around age three.
Evenflo Tribute LX Convertible Car Seat
A 9.4 lb convertible that Evenflo markets straight at families who fly, and the closest thing here to a Scenera NEXT with a little more comfort. It rear faces from 5 lb and forward faces to 40 lb, so it covers roughly the same span of childhood for about forty dollars more, with thicker padding and a removable head pillow. It is also narrow enough that owners report fitting three across a back seat. Evenflo does not publish aircraft certification on this product page, so check the label on the seat before you fly with it.
WAYB Pico Portable Car Seat
The only seat here designed from scratch for travel: 8 lb, an aluminium frame and mesh instead of moulded plastic, and a fold that fits an overhead bin rather than a checked bag. It is forward facing only and starts at 26.5 lb, so it is a toddler and preschooler seat, not something to fly with a baby in. FAA approved, and light enough that carrying it through a terminal on top of everything else is genuinely easy. The price is several times any other harnessed seat in this table, which is the whole argument against it.
Cosco Finale 2-in-1 Booster Car Seat
Eight pounds, under fifty dollars, and it harnesses a child to 65 lb before converting into a high back booster good to 100 lb, which is a lot of travelling life for the money. Only the harness mode is approved for the aircraft, because planes have lap belts and a booster needs a shoulder belt to work: fly it harnessed, then convert it at the destination. It is bare bones in the way the rest of the Cosco line is, and car seat technicians describe the booster conversion as fiddly rather than seamless.
mifold Comfort Grab-and-Go Booster
A backless booster that folds to about the size of a large paperback and weighs 1.75 lb, so it lives in a backpack or a glovebox instead of taking up a checked bag. It is destination gear rather than plane gear: boosters are not certified for use on an aircraft, so this rides in your carry-on and comes out at the rental car counter. Best for an older child who already sits well and only needs the adult belt lifted into the right place across the hips and shoulder.
BubbleBum Inflatable Backless Booster
An inflatable backless booster that weighs about a pound and deflates to roll up into nothing, which makes it the easiest thing in this table to pack. Like every booster it cannot be used on the plane, so treat it as gear for the taxi, the rental car and the friend picking you up. Its narrow profile is the other reason families buy it: three of them fit across most back seats, which matters when a rental car has to hold several children.
mifold hifold Fit-and-Fold Booster
A full high back booster that folds down small enough to go inside a carry-on, giving a child the head and torso support a backless booster cannot. At 10 lb it is heavier than every other booster here and heavier than all but one of the car seats, so choosing it is a decision about comfort and side protection rather than about packing light. It cannot be used on the aircraft, and its 243 adjustment settings are the reason to pick it over a cheaper booster for a long trip.
How we researched this
Weight decided who made the cut. Any seat without a published weight from its maker or a car seat review site was dropped, since that is the number you carry through an airport. That cut the Chicco KeyFit 35, the Cosco Scenera Extend and Rise LX, and the Evenflo Chase LX and LiteMax 30. The CARES aircraft harness was left out because it can't be used in a car, and the RideSafer travel vest because its maker doesn't state its weight or aircraft status and other sources disagreed. The Safety 1st Guide 65 and Evenflo SureRide are no longer listed by their brands.
Weight is the seat or carrier alone, without a base; BubbleBum states 500 g, shown here as 1.1 lb. Prices are a September 3, 2026 snapshot, and the Doona's $550 and Nuna's $650 include a base, while the boosters, convertibles and WAYB Pico are sold alone. Nuna's site showed no price, so its figure comes from a retailer. The two Evenflo aircraft approvals come from a car seat review site rather than Evenflo, and all three booster No values rest on the general FAA rule for boosters. Every cell is filled, but read the certification label on the seat before you book a seat for it.
