Can I use a car seat on the airplane itself?

US airlines allow FAA-approved child restraints in a purchased seat, and the seat must carry the approval label. Width matters on narrow aircraft seats. Check the Amazon listing for the current approval statement and your airline's policy before you fly.

Is it better to check a car seat or rent one at the destination?

Most US airlines check car seats for free, and bringing your own means you know its history and how to install it. Rental seats can be worn or unfamiliar. A light travel seat with a carry bag makes bringing your own much easier.

What is the lightest type of car seat for travel?

Folding forward-facing harness seats like the WAYB Pico are the lightest and most compact, but they are forward-facing only. Lighter convertible seats are the next option and work for younger children. Always confirm the age and weight limits on the listing.

How to choose

Look for the FAA-approved label if the seat will be used in an airplane seat.
Match the seat to your child's current age and weight, and to next year's.
Lighter seats are easier through airports but may give up recline or padding.
Rear-facing fit in a rental car depends on the vehicle; check before you go.
A travel bag or strap for the seat makes airport walks far easier.
Budget seats are fine for occasional trips; frequent flyers benefit from folding designs.
Confirm whether your airline lets you check the seat free of charge.

Watch out: Compatibility, the child's age and weight and the aircraft-use certification must always be checked before buying.
