Infants and children less than 2 years old may travel for free, on MetJet flights, if an adult holds the infant for the duration of the flight. However, if the adult intends to place the infant in an FAA-approved child restraint during take-off, landing or in flight a seat must be purchased for them. A birth certificate will be required upon arrival at the airport.
DO NOT INCLUDE THE CHILD IN THE PASSENGER COUNT WHEN BOOKING A TICKET.
