Decisions before you book
Budget by flight segment
Allegiant quotes its pet fee per carrier per segment. A connecting or return itinerary can involve more than one charge. Count the separately flown legs when requesting your total rather than treating a segment fee as the whole trip.
Allegiant — pet feePlan the extra cabin bag
Bring the pet carrier with either a personal item or a paid carry-on, not both. The pet must remain enclosed at the airport and on the aircraft; an additional bag does not provide another place to put the carrier.
Allegiant — baggage and confinementUse the answers for the route and operating flight you will actually take. A different cabin, aircraft or connection can change the result.
