MyFit Zip Air: questions answered

From Chicco's published specs, last checked 2026-11-06.

Will the Chicco MyFit Zip Air fit three across or in a small car?

It's narrower than 71% of the harness-to-booster seats we track, at 17.5 in. Fit depends on your vehicle; check each seat's manual and your vehicle manual. Car seat use and installation: see NHTSA's car seat page, which also lists free car seat inspection by certified technicians. Check the label and the maker's instructions, and ask your pediatrician about your child.

Can you bring the Chicco MyFit Zip Air on a plane?

Yes, Chicco lists it as certified for aircraft; look for the red-lettered label that says so. The FAA asks that a car seat go in a window seat so it doesn't block the aisle, and the crew will look for that label. It weighs 26 lb to carry through the airport.

Is it OK to buy a used MyFit Zip Air?

NHTSA publishes guidance on used car seats on its car seat page. Chicco lists a lifespan of 8 years from manufacture for this model. Check the label and the maker's instructions, and ask your pediatrician about your child.
