Can you bring breast milk on a plane with Frontier Airlines when traveling with a baby?
Bringing breast milk on Frontier Airlines
Yes — breast milk is allowed in carry-on and is exempt from the 3.4 oz/100 ml liquid rule. Declare it to TSA officers at the security checkpoint so it can be inspected.
- Pack breast milk in your carry-on and keep it chilled with ice packs or frozen gel packs; these may be screened separately.
- Containers larger than 3.4 oz are permitted for baby needs; expect inspection and possible testing (opening containers or swabbing).
- Breast pumps and parts are allowed in carry-on; gate-checking a pump is also an option if needed.
- Label bottles if possible, bring extra supplies (bottles, storage bags, wipes) and a cooler bag for transport.
- Checked baggage storage is allowed but not recommended due to temperature control and risk of loss.
- For international travel, check destination rules and customs regarding bringing milk into the country.
If you need help at the checkpoint or gate, Frontier staff and TSA officers can assist — ask calmly and early.
