| # | Product | Best for | Score | Price |
|---|---|---|---|---|
| 1 |  Cosco Scenera NEXTAbout 7 lb and 17 in wide, rear-facing 5-40 lb and forward-facing 22-40 lb, with the FAA approval label on the shell — the standard answer for a reason. | The lightest genuinely FAA-approved seat to carry | 9.2 | |
| 2 | Cosco Scenera ExtendAbout 9 lb, rear-facing 5-40 lb and forward-facing 30-50 lb, certified for use in commercial aircraft — two pounds more for ten more pounds of range. | Rear-facing longer, and forward-facing to 50 lb | 8.9 | |
| 3 | WAYB Pico Travel Car Seat8 lb, folds to 11.6 x 14.5 x 18.9 in — it is the only car seat here that fits in an overhead bin, which changes the whole logistics problem. | A forward-facing child and an overhead bin | 8.8 | |
| 4 |  Chicco KeyFit 35 Infant Car SeatA 10.4 lb carrier that clicks out of an 8.6 lb base, rear-facing 4-35 lb — the practical choice when the child is too small for anything else. | An infant trip where you need a carrier seat | 8.4 | |
| 5 | AmSafe CARES Child Aviation Restraint System11 oz, FAA approved as the only harness-type child aviation restraint — for the flight only, and it does not work in a car. | A 22-44 lb child on a flight where you will not need a car seat | 8.6 |
The car seat you have installed at home is almost certainly the wrong one to fly with, and the reason is weight: a well-padded convertible seat can be three times the weight of a purpose-bought travel seat. Published weights below run from about 7 lb to 17.2 lb. That gap is the entire decision. The wider category is our strollers and car seats hub.
The numbers
| Seat | Weight | Rear-facing | Forward-facing | Air travel |
|---|---|---|---|---|
| Cosco Scenera NEXT | ~7 lb | 5-40 lb | 22-40 lb | FAA approved |
| WAYB Pico | 8 lb | Not supported | 22-50 lb, 30-45 in | FAA approved |
| Cosco Scenera Extend | ~9 lb | 5-40 lb | 30-50 lb | Certified for commercial aircraft |
| Chicco KeyFit 35 | 10.4 lb carrier, 20 lb with base | 4-35 lb | Not applicable | Infant carrier |
| AmSafe CARES harness | 11 oz | n/a | 22-44 lb, under 40 in | Only FAA-approved harness device |

What the FAA publishes
The FAA does not require a child restraint system on a commercial flight, but its published position is clear: the safest place for a child under two is in an approved CRS or device, not in an adult’s lap, and it strongly discourages lap-holding. It also states plainly that buying a ticket for the child is the only way to guarantee you can use a CRS (faa.gov, read 2026-09-27).
The approved devices are a forward- or rear-facing hard-backed child safety seat, plus the AmSafe CARES harness, which the FAA certifies for children up to 40 in tall weighing 22 to 44 lb and able to sit upright unaided (faa.gov, read 2026-09-27). Nothing else. Our car seat on a plane guide works through the practicalities.
Which one, for which trip
One seat, any age, cheapest: the Cosco Scenera NEXT. Seven pounds, 17 in wide, and the approval label is where Cosco says it is. It is the standard answer in this category and it earns it.
A forward-facing child and a carry-on: the WAYB Pico. It is the only car seat here that folds into an overhead bin, and that removes the single most annoying part of flying with a seat.
A newborn: the Chicco KeyFit 35, and leave the base at home. A 10.4 lb carrier is manageable; 20 lb with the base is not, and the belt install works fine once you have practiced it.
A 22-44 lb child with a car waiting: the CARES harness for the flight and whatever seat is at the other end. Eleven ounces against seven pounds is not a close call — as long as you genuinely have a seat at the destination.
The cheapest seat in this category is not a compromise
| Weight | about 7 lb |
|---|---|
| Width | 17 in at its widest point |
| Rear-facing | 5-40 lb |
| Forward-facing | 22-40 lb |
| Air travel | FAA approved; the label is on the left side near the rear-facing belt path |

Every car seat sold in the US has to meet the same federal standard, FMVSS 213. A cheap seat is not a less safe seat; it is a seat with less padding, fewer adjustment mechanisms and a lower weight ceiling. For a week of taxis and one flight, those are exactly the right things to give up.
What we’d skip
Booster seats, on a plane. Not FAA approved for taxi, takeoff or landing. The CARES harness is the approved alternative for a child in that size range.
Inflatable or belt-positioning travel devices other than CARES. CARES is the only FAA-approved harness-type device. Anything else making a similar claim is not.
Bringing a full-size home convertible seat. Twenty-plus pounds through an airport when a 7 lb seat exists is a choice you will regret at the second gate change.
Second-hand car seats of unknown history. Seats expire and crash history is not visible. This is the one category where borrowing is a bad idea.
Every pick in full
Cosco Scenera NEXT
About 7 lb and 17 in wide, rear-facing 5-40 lb and forward-facing 22-40 lb, with the FAA approval label on the shell — the standard answer for a reason.
Best for: The lightest genuinely FAA-approved seat to carry
| Weight | about 7 lb |
|---|---|
| Width | 17 in at its widest point |
| Rear-facing | 5-40 lb |
| Forward-facing | 22-40 lb |
| Air travel | FAA approved; the label is on the left side near the rear-facing belt path |
Specs from Safe in the Seat — Cosco Scenera NEXT review, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- About 7 lb — the lightest seat in this list by a wide margin
- 17 in at its widest point, so it clears a narrow aisle and does not need the armrest up
- Rear-facing 5-40 lb, forward-facing 22-40 lb
- FAA approved; the label is on the left side near the rear-facing belt path
Bad at
A 40 lb forward-facing ceiling is lower than a home convertible seat, so it is not a one-and-only seat. And at this price the padding is minimal — fine for a week, less so for a daily commute.
How it scores (out of 10)
Overall 9.2 — a research score against published specs, not a test result. See how we pick.
IllustrativeCosco Scenera Extend
About 9 lb, rear-facing 5-40 lb and forward-facing 30-50 lb, certified for use in commercial aircraft — two pounds more for ten more pounds of range.
Best for: Rear-facing longer, and forward-facing to 50 lb
| Weight | about 9 lb |
|---|---|
| Rear-facing | 5-40 lb |
| Forward-facing | 30-50 lb |
| Air travel | certified for use in commercial aircraft |

Good at
- Rear-facing 5-40 lb, forward-facing 30-50 lb
- About 9 lb
- Certified for use in commercial aircraft
Bad at
Two pounds heavier than the NEXT, which matters when you are carrying it through a terminal with a child and a bag. Cosco does not publish a width figure for it on the page we read.
How it scores (out of 10)
Overall 8.9 — a research score against published specs, not a test result. See how we pick.
IllustrativeWAYB Pico Travel Car Seat
8 lb, folds to 11.6 x 14.5 x 18.9 in — it is the only car seat here that fits in an overhead bin, which changes the whole logistics problem.
Best for: A forward-facing child and an overhead bin
| Weight | 8 lb |
|---|---|
| Folded | 11.6 x 14.5 x 18.9 in — fits an overhead bin |
| In use | 15.2 x 14.5 x 22.8 in (lowest) to 15.2 x 14.5 x 27.8 in (highest) |
| Forward-facing only | 22-50 lb, 30-45 in |
| Air travel | FAA approved; backpack-style carry bag |
Specs from Car Seats For The Littles — WAYB Pico review, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- 8 lb, FAA approved, with a backpack-style carry bag
- Folds to 11.6 x 14.5 x 18.9 in — fits an overhead bin
- In use 15.2 x 14.5 x 22.8 in (lowest) to 15.2 x 14.5 x 27.8 in (highest)
- Forward-facing 22-50 lb, 30-45 in
Bad at
Forward-facing only. It cannot be used rear-facing at all, which rules it out for infants and for anyone following extended rear-facing guidance.
How it scores (out of 10)
Overall 8.8 — a research score against published specs, not a test result. See how we pick.
IllustrativeChicco KeyFit 35 Infant Car Seat
A 10.4 lb carrier that clicks out of an 8.6 lb base, rear-facing 4-35 lb — the practical choice when the child is too small for anything else.
Best for: An infant trip where you need a carrier seat
| Carrier weight | 10.4 lb |
|---|---|
| Base weight | 8.6 lb |
| Carrier + base | 20 lb (9.07 kg) |
| Capacity | 4-35 lb, rear-facing |
Specs from Chicco KeyFit 35 Infant Car Seat product page, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- Rear-facing 4-35 lb, suitable from newborn
- Carrier 10.4 lb on its own; base stays in the car
- Carrier can be carried by hand, unlike a convertible seat
Bad at
20 lb for carrier plus base, and the base is the part that makes installation quick. Leave the base at home and you get the weight down at the cost of a slower belt install at every stop.
How it scores (out of 10)
Overall 8.4 — a research score against published specs, not a test result. See how we pick.
IllustrativeAmSafe CARES Child Aviation Restraint System
11 oz, FAA approved as the only harness-type child aviation restraint — for the flight only, and it does not work in a car.
Best for: A 22-44 lb child on a flight where you will not need a car seat
| For children | 22-44 lb, 40 in or less, able to sit upright unaided |
|---|---|
| Weight | 11 oz |
| Approval | the only FAA-approved harness-type child aviation restraint |
| Install | the brand states under 60 seconds; packs into a carry-on |
Specs from AmSafe CARES product page, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- 11 oz — a fraction of any car seat
- The only FAA-approved harness-type child aviation restraint
- For children 22-44 lb, 40 in or less, able to sit upright unaided
- Brand states it installs in under 60 seconds and packs in a carry-on
Bad at
It is not a car seat. It cannot be used in a vehicle, so if you need a seat at the destination you are carrying one anyway and the CARES saves you nothing.
How it scores (out of 10)
Overall 8.6 — a research score against published specs, not a test result. See how we pick.
IllustrativeQuestions parents actually ask
What is the lightest FAA-approved car seat?
Of the seats we compared, the Cosco Scenera NEXT at about 7 lb, then the WAYB Pico at 8 lb and the Cosco Scenera Extend at about 9 lb. The AmSafe CARES harness is 11 oz but it is not a car seat — it works on an aircraft only.
Does the FAA require a car seat on a plane?
No. The FAA does not require child restraint systems on commercial flights, but it strongly recommends them and states that the safest place for a child under two is in an approved CRS rather than an adult's lap. Buying a ticket for the child is the only way to guarantee you can use one.
What counts as FAA approved?
A forward- or rear-facing hard-backed child safety seat bearing the approval label, or the AmSafe CARES harness, which the FAA certifies for children up to 40 in tall weighing 22 to 44 lb. Booster seats and belt-positioning devices other than CARES are not approved for use during taxi, takeoff and landing.
Do I need the base for an infant seat?
No — infant carriers can be installed with the vehicle belt alone, and the base is what makes it fast. Leaving the 8.6 lb Chicco base at home cuts your carried weight by nearly half, at the cost of a proper belt install at every car. Learn the belt path before you travel.
Where is the FAA approval label?
On the seat's shell, usually on a side. On the Cosco Scenera NEXT it is on the left side near the rear-facing belt path. Know where yours is before you fly — being able to point at it ends the conversation with a crew member in five seconds.
