Lap Infants (Under Age 2) on Domestic vs. International Flights
On US domestic flights, infants under 2 years old can travel on an adult’s lap free of airfare. On international flights, airlines typically charge 10% of the adult base fare plus government airport taxes and require a ticketed infant e-ticket and passport.
Free Stroller & Car Seat Gate-Check Allowances
Every major airline allows families traveling with an infant or toddler to check 1 stroller and 1 FAA-approved child safety seat free of charge—either at the ticket counter or right at the aircraft boarding door (gate-check).
Requesting Bulkhead Bassinets on Long-Haul Widebodies
Widebody jets (787, 777, A350, A330, A380) feature wall-mounted skycots/bassinets at bulkhead rows for infants up to ~20–24 lbs. Reserve bulkhead seats and request the bassinet through the airline immediately after ticketing.
Frequently Asked Questions
Does a lap infant need a passport for an international flight?
Yes. Every passenger—including a newborn lap infant—must have their own valid passport for international air travel.
Can I bring breast milk, formula, and baby food through TSA over 3.4 oz?
Yes. TSA exempts breast milk, infant formula, toddler drinks, and puree pouches in reasonable quantities above 3.4 oz (100 ml); simply declare them to the TSA officer for screening.
