Because airline child policies change — and parents shouldn’t have to hunt for answers.

Yes — you can bring breast milk when flying with Spirit. Follow TSA screening rules and Spirit’s usual allowance for infant items:

Carry it in your carry-on when possible — this makes screening and access easier.
Breast milk is exempt from the 3.4 oz/100 ml rule, so larger amounts are allowed for infants. Declare it at the security checkpoint.
Security will screen the milk separately. If X-ray is refused for privacy, an alternative inspection (like opening the container) may be offered.
Frozen milk, ice packs, and coolers are permitted. Partially melted ice is usually allowed but must be declared and screened.
Breast pumps and spare parts can be carried through security; they may be X-rayed separately.
For international travel or specific baggage questions (limits, fees, connecting carriers), check with Spirit before you fly and arrive early to allow time for screening.
