FAA-approved (flying) car seats

Certified for use on aircraft. Harnessed seats qualify; boosters do not.

๐Ÿ›Ÿ Fit is decided by your seat manual + your vehicle manual. This page lists published specs to help you shortlist โ€” it is not installation or safety advice, and it does not confirm a seat fits a specific car. Confirm install with the manuals, NHTSA, or a free certified car-seat technician (CPST) check.

Flying: harnessed seats (infant + convertible + all-in-one in harness mode) are FAA-approved for aircraft; boosters are NOT โ€” a plane seat has no shoulder belt for a booster to position.
