A one-way fee of $99 is charged for each pet. Pets must be at least 8 weeks old and remain in their carrier for the duration of the flight. The carrier must be large enough for the pet to stand, turn around, and lie down comfortably, and it must fit under the seat in front of you.
Cargo Policy
Frontier Airlines does not offer cargo or checked baggage services for pets. All pets must travel in the cabin with their owner.
