In-cabin pet travel · Delta
Can your dog or cat fly in-cabin on Delta?
Short answer: usually yes — if your pet is small enough to ride in a carrier that fits under the seat in front of you, and you book the pet spot before the flight fills its per-cabin limit. The catch is that every airline measures its under-seat space differently, so the only question that matters is whether your carrier fits Delta’s. Check that below in about 30 seconds.

What flying in-cabin with a pet on Delta generally involves
General guidance
Your pet has to fit under the seat — and stay there
In-cabin travel is for small dogs and cats that can stand up and turn around inside a carrier that slides fully under the seat in front of you. The carrier stays down for the entire flight — it can’t go on your lap, in the overhead bin, or in a bulkhead/exit row. If your pet is too big for that, it doesn’t fly in the cabin. Confirm the exact allowed carrier size on Delta’s official pet page before booking — and use the finder above to check your specific carrier.
General guidance
Book the pet slot early — cabins cap how many animals fly
Airlines limit the number of pets allowed in the cabin per flight, and that’s usually first-come, first-served with a per-pet fee paid at booking or check-in. Add your pet to the reservation as early as you can, especially on busy routes and holidays — showing up gate-day without a reserved slot can mean your pet doesn’t board. Confirm the current fee and how to reserve on Delta’s official pet page before booking.
General guidance
Bring rabies and health paperwork
Most trips expect a current rabies vaccination record, and many destinations (and international routes) require a veterinary health certificate issued shortly before travel. Carry printed copies in your carry-on, not just photos. Requirements vary by destination and change, so confirm exactly what’s needed on Delta’s official pet page — and with your vet and the destination’s import rules — before booking.

Flying in-cabin with a pet on Delta: common questions
Can my dog or cat fly in the cabin on Delta?
Usually yes for a small dog or cat — as long as it can stand up and turn around inside a carrier that slides fully under the seat in front of you, and there's still an open pet slot on your flight. Pets too big for that don't fly in the cabin. Confirm the exact size and weight limits on Delta's official pet page before booking.
How much does it cost to bring a pet in-cabin on Delta?
Airlines charge a per-pet fee, typically paid at booking or check-in, but the amount changes and varies by route, so we won't quote a number that could be wrong. Confirm the current in-cabin pet fee directly with Delta before you book.
What size carrier do I need for Delta?
Your carrier has to fit completely under the seat in front of you, and every airline measures that space a little differently. Rather than trust a generic number, enter your carrier's dimensions and your pet's weight into the carrier finder to check it against Delta's rules on file — and confirm the current maximum dimensions on Delta's official pet page before you buy a carrier.
Do I need a rabies certificate or health papers to fly with my pet on Delta?
Most trips expect a current rabies vaccination record, and many destinations — especially international ones — also require a veterinary health certificate issued shortly before travel. Carry printed copies, not just phone photos. Because requirements depend on where you're going and change often, confirm exactly what's needed with your vet, with Delta, and with the destination's import rules before booking.
How early should I book my pet's spot on Delta?
As early as you can. Cabins cap how many pets fly per flight and it's generally first-come, first-served, so on busy routes and holidays slots fill up. Add your pet to the reservation up front — showing up gate-day without a reserved slot can mean your pet doesn't board. Confirm how to reserve a pet slot with Delta.
Can I bring a larger dog or buy an extra seat for my pet on Delta?
In-cabin travel is only for small pets that fit under the seat — a larger dog generally can't ride in the cabin as a regular pet and would need cargo/checked options where offered, which many airlines limit or don't provide. Trained service animals follow separate rules. Confirm Delta's service-animal and larger-pet policies directly, since these differ significantly by airline and change.
