Quick answer: Alaska runs one of the most complete pet programmes of any US airline. A pet can travel in the cabin, in the climate-controlled baggage compartment on your own flight, or as a separate cargo shipment — and the checked list goes well beyond cats and dogs, taking ferrets, guinea pigs, rabbits, household birds, non-poisonous reptiles, pot-bellied pigs and tropical fish. Cabin capacity is unusually generous too, commonly around eight animals in the main cabin and three in first. Call a travel expert at Fond Travels on +1 (323) 800 6001 and we will work out which of the three routes suits your animal.

Three routes, and how to choose between them
- In the cabin — the animal stays in a kennel under the seat for the whole flight, subject to availability. Best for the animal where it is an option.
- Checked into the baggage compartment — climate-controlled, on your own flight, for animals too large for the cabin. Reported combined weight limit around 150 pounds for animal and carrier, with a vet-issued health certificate required.
- Separate cargo — booked through the airline's cargo arm, for animals travelling without you or where the checked route is not available.
The cabin is almost always easier on the animal: same air, same temperature, your presence, and no loading process. The checked route exists because many dogs simply cannot fit under a seat, and on this airline it is a genuine option rather than an afterthought.
The species list, which is unusually wide
This is where the airline differs most from its peers, and it matters if you own something other than a cat or a dog.
- In the cabin: cats, dogs, rabbits and small household birds, with trained service animals handled separately. On flights to Hawaii, Canada or international destinations the cabin list narrows to cats and dogs only.
- Checked into the baggage compartment: a far longer list — cats, dogs, ferrets, guinea pigs, hamsters, household birds, non-poisonous reptiles, pot-bellied pigs, rabbits and tropical fish.
If your pet is a ferret or a rabbit, most airlines will not carry it at all. That makes this one worth knowing about even if it is not the obvious carrier for your route.
Cabin capacity and ages
- Commonly around eight animals in the main cabin and three in first — more than most carriers, which makes a late booking less likely to fail.
- Dogs and cats must be at least 8 weeks old and weaned for at least five days before departure.
- The kennel must fit under the seat and the animal must be able to remain in it comfortably for the whole flight.
- Book as early as you can anyway. Generous is not unlimited, and holiday periods fill.
