Start with the seating decision, then pack for the whole journey—not just the hours in the air. Keep feeding and changing supplies with you, with enough extra for a delay, rather than building a separate bag for every possible problem.

This checklist uses U.S. safety guidance and TSA screening rules. For other departures, check the local security authority; confirm infant policies with the airline operating each flight.

Before booking: seat, documents and baby gear

  • [ ] Choose a separate seat with an aircraft-approved car seat where possible. The NTSB recommends buying a ticket for children under two and using an appropriately sized, aircraft-certified restraint. Holding a baby on your lap does not provide equivalent protection during turbulence. NTSB child passenger safety guidance
  • [ ] Check the car seat’s approval label, instructions and fit. Confirm its use in your chosen cabin and seat position with the airline. Install rear-facing or forward-facing according to the manufacturer’s limits; aircraft harnesses intended for larger children are not an infant substitute. American Academy of Pediatrics guidance
  • [ ] Add the infant to the reservation, including when traveling on your lap. Check minimum age, any medical-clearance requirement, infant charges and proof-of-age documents. For example, American requires lap infants to be included in the reservation and may request proof of age. American’s infant policies
  • [ ] Check the baby’s international documents separately: passport, entry requirements and any consent paperwork when traveling without both parents. Do not assume the adult’s documents cover the infant. American’s international-document guidance
  • [ ] Confirm stroller, car-seat and diaper-bag allowances, including gate-check eligibility and where gear will be returned during connections. These are airline-specific, not TSA rules.
  • [ ] If requesting a bassinet, check aircraft availability, size limits and allocation rules. Do not build the flight around guaranteed access. American, for example, allocates bassinets first-come at the gate on specified aircraft. American’s baby-gear and bassinet rules

The American examples reflect its published policies checked in November 2026; recheck before booking.

For a newborn, premature infant or baby with a health concern, discuss the trip with their clinician before booking. Prefer fewer transfers and a connection that leaves time for feeding and changing over the shortest possible itinerary.

Pack one cabin kit with three small sections

Use your baby’s normal feeding and changing frequency to estimate quantities for home-to-accommodation travel, then add a delay buffer. There is no useful universal diaper count.

Feeding

  • [ ] Usual milk or formula, plus extra feeds
  • [ ] Enough bottles and nipples for the journey; bib and burp cloth
  • [ ] Cooling supplies if needed, following safe storage and preparation instructions for your milk or formula
  • [ ] Pacifier, if used, and a spare
  • [ ] Age-appropriate food and spoon if your baby already eats solids

Do not rely on the crew to provide your usual formula, sterilize bottles or refrigerate milk.

Changing

  • [ ] Diapers, wipes and changing mat
  • [ ] Small diaper-cream container
  • [ ] Bags for dirty clothing and used diapers
  • [ ] Two complete baby clothing changes and one spare adult top

Comfort and essentials

  • [ ] Easily removable clothing layers
  • [ ] One or two familiar, washable toys
  • [ ] Usual medicines and any clinician-provided instructions
  • [ ] Baby’s documents in an accessible pocket

Keep a single-change pouch handy; leave the reserve supplies deeper in the bag. Move these essentials out before any cabin bag is checked at the gate. Use the general pre-flight checks for adult documents and baggage rather than duplicating them here.

At security and the gate

  • [ ] Separate feeding liquids for screening. TSA permits formula, breast milk and baby food above 3.4 ounces/100 ml without fitting them into the quart-sized liquids bag. Cooling packs are also allowed. Tell the officer at the start and remove these items for separate screening; additional checks may be required. TSA traveling-with-children rules
  • [ ] Prepare to empty and fold the stroller. TSA screens strollers, carriers and car seats; oversized equipment receives physical inspection. Remove the baby from a stroller or car seat and follow the officer’s instructions for carrying them through screening. TSA screening procedures
  • [ ] Change the diaper before boarding, refill your own water and confirm gate-check tags and collection points.
  • [ ] Ask about early boarding if you need time to install the car seat.

In the cabin: restraint, feeding and rest

  • [ ] If using a car seat, keep its harness fastened during taxi, takeoff, landing and whenever the seat-belt sign is on. Follow crew instructions. American’s safety-seat requirements
  • [ ] If traveling with a lap infant or using a bassinet, follow the crew’s instructions for takeoff, landing and turbulence. A bassinet is not a substitute for an approved child restraint; lap travel remains less protective.
  • [ ] Have a pacifier ready for pressure changes. Breastfeeding, bottle-feeding or sucking a pacifier can ease ear discomfort during takeoff and landing, but do not unbuckle the baby from a required restraint to feed.
  • [ ] Ask which lavatory has a changing table before you need it.
  • [ ] If using a bassinet, keep its firm, flat sleep surface free of bedding and toys. If the baby sleeps on your lap, stay awake and alert, check their breathing often and keep their face uncovered.

The ear-comfort and sleep advice follows AAP infant-flight guidance. Keep arrival day light: arrange suitable transport and a place to feed and change before adding sightseeing.
