Read the aircraft label on the actual seat
The FAA recommends an approved child restraint for young children on a flight. For a US-certified car seat, look for the label confirming certification for motor vehicles and aircraft. Read the aircraft section of its manual; approval of a product family does not establish approval of every configuration.
Book around the restraint
For a child under two, buying a separate ticket is the only way to guarantee use of a child restraint, according to the FAA. Check the airline’s permitted seating locations and the seat’s installation instructions before booking. Keep the manual accessible during boarding.
A booster is a different case
The FAA prohibits booster-seat use during ground movement, takeoff and landing. A belt-positioning booster needs a lap-and-shoulder belt; do not assume it can serve as an aircraft restraint. A combination seat’s harness configuration needs its own certification check.
Plan the transfers, too
Write down every transfer: home to airport, gate to aircraft, arrival to accommodation. Who carries the seat while handling bags? Will the destination vehicle have the installation equipment your seat needs? A lighter seat may simplify carrying, but the whole route still needs a workable plan.
Which car seats are certified for aircraft use?
Certification is printed on the seat itself, and it follows the type of restraint more than the brand. Across this catalogue:
| Seat type | Certified | Not certified | Not stated |
|---|---|---|---|
| Infant | 52 | 1 | 10 |
| All-in-one | 42 | 4 | 18 |
| Convertible | 24 | 3 | 2 |
| Harness-to-booster | 15 | 0 | 5 |
| 2-in-1 booster | 0 | 22 | 2 |
| Backless booster | 0 | 16 | 3 |
| High-back booster | 0 | 9 | 0 |
Boosters are the clear pattern: a booster needs a lap-and-shoulder belt, and aircraft seats have a lap belt only. Check the label on your own seat, because certification belongs to the model, not the type.
Common questions
Can you take a car seat on a plane?
Yes, if it is certified for aircraft use. The certification is printed on the seat as a red statement that it is certified for use in motor vehicles and aircraft. In this catalogue, harnessed seats carry it far more often than boosters do.
Are booster seats allowed on planes?
Generally no, and the table above shows why: a booster positions a lap-and-shoulder belt, and an aircraft seat has a lap belt only. A booster may still be checked or carried on for use at the destination.
Do I need to buy a seat for my child to use a car seat on board?
Yes. A car seat needs its own purchased seat, installed in an approved position that the airline allows, which is usually a window seat and never an exit row. Confirm the rule with the airline before booking.
