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

Short answer: Yes, usually — with some common-sense rules.

Carry-on is best: Bring the bottle warmer in your carry-on so you can protect it and access it during travel.
Security rules: Empty warmers are straightforward to screen. If it contains liquids, remember TSA rules — baby formula, breast milk and expressed milk are allowed in quantities greater than 3.4 oz but must be declared at security.
Batteries: If the warmer has a removable lithium battery, follow airline/TSA battery rules — spare lithium batteries should go in carry-on and may need insulation on terminals; larger batteries can require airline approval.
Onboard use: Airlines and flight crews control use of heating devices. You may not be allowed to plug in or run a warmer in flight; flight attendants can usually provide hot water to warm bottles.
Checked baggage caution: You can check a warmer, but electronics can be damaged and spare batteries are not allowed in checked bags.

If in doubt, pack it in carry-on, declare any baby liquids at security, and confirm details with Allegiant before travel.
