Pet Policy Overview
Frontier Airlines is a US ultra-low-cost carrier that accepts small dogs, cats, rabbits, guinea pigs, hamsters, and small household birds in the cabin on domestic flights. The airline does not offer any checked baggage or cargo pet transport. Frontier's budget-friendly base fares combined with a $99 pet fee make it one of the more affordable options for domestic US cat travel, though the airline's network focuses on leisure routes with limited international service.

Pro Tip
Frontier allows you to add a pet during the online booking process, which is a convenience many legacy carriers lack. Only soft-sided carriers are permitted — no hard-sided options. The carrier counts as your personal item, so you will not have a separate personal item allowance. Book early as there is a strict limit per flight. Frontier's seat pitch is tight, so verify your carrier fits under the seat, especially on A321neo aircraft.
Restrictions
Domestic US flights only — no international pet transport. No checked baggage or cargo options whatsoever. Only one pet per carrier, one carrier per passenger. Pets must remain inside the carrier throughout the entire flight. Not permitted in exit rows. Snakes, reptiles, ferrets, rodents (except hamsters/guinea pigs), spiders, and insects are banned.
