If you are travelling with an infant and have purchased a separate seat for the infant, the following types of car seats are acceptable onboard:
Car seats that are approved for use in aircraft by JAA authority, the FAA or Transport Canada (based on a national technical standard); these are marked accordingly.
Car seats approved for use in motor vehicles and aircraft according to US FMVSS No 213 and are manufactured to these standards on or after February 26, 1985.
