How to Book a Flight for a Baby or Infant

Flying with an infant has its own booking checklist — fare rules, seat and bassinet requests, and the infant's own travel documents — that's worth working through before you book, not the week of travel.

1. Check the airline's specific age cutoffs and documentation

Infant fare eligibility and required documents vary by airline — check these directly rather than assuming a universal rule.

2. Request a bassinet or extra-legroom seat early

These are limited and allocated on request, so book or ask as early as possible rather than assuming availability at the gate.

3. Check baggage allowance for a stroller or car seat

This is usually handled separately from standard baggage — confirm the specific policy.

4. Check if the infant needs their own passport

Most countries require this regardless of age, along with any destination-specific entry documents.

5. Pack essentials in cabin baggage

Keep nappies, formula, and a change of clothes accessible in case of checked-baggage delays.

Quick tips

  • Confirm whether the infant needs their own paid seat or can travel as a lap infant under the airline's specific age rules.
  • Check if formula and baby food are exempt from standard liquid restrictions at security, since rules for this vary.
  • Bring extra supplies beyond what you think you'll need, in case of flight delays.
  • Check the specific bassinet weight and size limit if requesting one, since infants outgrow eligibility at a certain point.
