Allegiant oxygen rules at a glance

NoticeTell Allegiant you plan to use a POC onboard. Doing it when you book is easiest.
BatteriesCarry enough batteries for the whole flight plus a conservative estimate for delays. We suggest planning for 150%. POCs run on battery only; there are no outlets onboard.
SeatingWindow seats only, with the POC under the seat in front of you. No exit row or bulkhead seats.
AlarmsYou must be able to hear and see the unit’s alarms and respond, or travel with someone who can.
PackingProtect spare batteries from short circuits and damage in your carry-on.
FeesThere’s no fee to bring medical equipment onboard.

Allegiant doesn’t allow you to bring your own oxygen tanks, so an FAA-approved portable concentrator is the way to fly. Policies can change, so always confirm with Allegiant Air before you fly. See Allegiant’s policy →
