Can I bring breast milk or formula through security?

Yes. TSA allows 'reasonable quantities' of breast milk, formula, and baby food in excess of 3.4 ounces. Inform the officer at the start of screening that you have these items.

Does my baby need a ticket if they sit on my lap?

Yes. Even if they don't pay a full fare, they must be issued a 'lap infant' ticket or boarding pass linked to your reservation.

When does a lap infant have to start paying for a seat?

Once the child turns two, they are legally required by the FAA to have their own purchased seat.

Booking Flights with a Baby

Book your infant as a 'lap infant' if they are under two years old to save on ticket costs, but consider purchasing a separate seat and using a FAA-approved car seat for safety. Always call the airline immediately after booking to add the infant to your PNR and request a bulkhead bassinet seat if available.

Choose your seating strategy. Decide between a lap infant (free on domestic flights, 10% of adult fare + taxes on international) or a separate seat. A separate seat allows you to use your car seat, which is safer and keeps your hands free.
Add the infant to your reservation. If booking online, look for the 'add infant' option. If the airline website doesn't allow it, book your ticket first, then call the airline's customer service desk immediately to link the infant to your PNR (Passenger Name Record).
Request a bassinet. If flying internationally, call the airline to request a bulkhead bassinet seat. These are limited in number and usually assigned on a first-come, first-served basis.
Verify baggage allowances. Check the airline's policy on strollers and car seats. Most allow you to check these for free in addition to your standard baggage allowance, but always confirm if they must be gate-checked or checked at the oversized luggage counter.
