Airline Pet Policy
Delta is one of the few airlines that will fly a bird in the cabin, and one of the few legacy carriers that no longer flies most pets in cargo. Small dogs, cats, and household birds ride under the seat for a flat fee each way on domestic flights. Anything bigger is a problem, because Delta Cargo is closed to the general public and checked pets are reserved for military and State Department travelers. The other catch is international, where a long list of countries will not take a cabin pet at all.
In this guide
Delta Air Lines lets small dogs, cats, and household birds fly in the cabin on domestic flights, as long as the pet fits in a ventilated kennel that slides under the seat in front of you. The pet has to be at least 8 weeks old for domestic travel, and the cabin fee is $150 each way per kennel within the US, Canada, Puerto Rico, and the US Virgin Islands. Spots per flight are capped and go first-come, so you reserve by phone.
The harder part is what happens if your pet does not fit. Delta Cargo is not open to the general public for pets in 2026, and checked baggage in the hold is limited to active US military and State Department travelers on orders. For most people the honest read is cabin or nothing, and international travel comes with its own long list of banned destinations.
Birds are the surprise. Delta is unusual in allowing small household birds like parakeets and canaries in the cabin, but only on domestic flights within the contiguous US. Birds are never accepted on international routes.
The headline number is $150 each way for a cabin pet, charged per kennel and per direction of travel, so a round trip runs about $300. That domestic fee went up from $95 in April 2025, so any guide still quoting $95 is out of date. International cabin travel, where it is allowed at all, costs more.
| Travel type | Fee | Notes |
|---|---|---|
| In-cabin, US / Canada / Puerto Rico / USVI | $150 each way, per kennel | Round trip about $300, rose from $95 in April 2025 |
| In-cabin, international | $200 each way, per kennel | Only where cabin pets are allowed |
| Checked baggage or Delta Cargo | Restricted | Military and State Dept on orders only, not the general public |
What the fee buys you. A guaranteed under-seat spot for your pet and the ability to keep them with you the whole flight. The kennel is separate from your carry-on allowance, so you can bring the pet plus one carry-on or personal item. You pay the fee at check-in, not during online booking.
The kennel is where most cabin plans succeed or fall apart on Delta, and it is trickier than on most airlines, because Delta does not publish a single hard size. It publishes a recommendation and then tells you to check your specific aircraft, which is easy to miss.
| Requirement | Detail |
|---|---|
| Pets accepted in cabin | Small dogs, cats, and household birds (birds domestic only) |
| Minimum age | 8 weeks for domestic, older for international |
| Recommended kennel | Soft-sided, about 18 x 11 x 11 in |
| Real constraint | Must fit the under-seat space of your specific aircraft |
| Fit | Pet stands, turns around, and lies down inside |
| Allowance | 1 kennel plus 1 carry-on or personal item |
| Per kennel | 1 pet, with limited litter and same-size pair exceptions |
The 18 x 11 x 11 trap. Delta recommends a soft-sided kennel of 18 x 11 x 11 inches, but the actual under-seat height on many Delta jets is closer to 9 inches. A rigid case that measures fine on paper can fail to fit a 737-900ER or a 717. A soft-sided bag is the safer bet because it compresses, and it is worth checking the exact aircraft on your booking before you buy a carrier.
One kennel per passenger is the rule, with two narrow exceptions on domestic flights: a female cat or dog can travel with her litter aged 8 weeks to 6 months, and two pets of the same breed and size in that same age range can share one kennel and be charged as a single pet. Beyond those cases, it is one animal per kennel.
These three routes used to be the reason people chose a legacy airline like Delta over a low-cost one. That has changed. Two of the three lanes are now closed to ordinary travelers, which is the single most important update in the current policy.
| Option | Best for | Who can use it |
|---|---|---|
| In-cabin | Small dogs, cats, birds under the seat | Any passenger, on allowed routes |
| Checked baggage | Pets too big for the cabin | US military on PCS orders and State Dept only |
| Delta Cargo | Larger pets as freight | Not available to the general public in 2026 |
The practical effect is stark. If you are a civilian with a dog too big for an under-seat kennel, Delta cannot fly it, in the cabin, as baggage, or as cargo. Your options become a specialized pet-relocation shipper or a cargo-capable airline. It is worth comparing how the American Airlines pet policy and the United pet policy handle larger pets before you assume Delta can take yours.
This is where Delta is far more restrictive than its reputation suggests, and where the surprises happen mid-booking. Cabin pets are allowed on some international routes, but only if you meet every document, health, age, and kennel rule, and a long list of destinations refuse cabin pets outright.
| Route | Cabin pet allowed? |
|---|---|
| Contiguous US, Canada, Puerto Rico, US Virgin Islands | Yes |
| To or from Hawaii | No, not even in cargo |
| UK, Ireland, Australia, New Zealand | No cabin pets, cargo only |
| Brazil, Colombia (originating there) | No, under embargo |
| Hong Kong, UAE, South Africa, Iceland, Jamaica, and others | No cabin pets |
| International premium cabins (Delta One, flat-bed seats) | No pets |
Birds never fly internationally, only domestic. Dogs entering the United States must also meet current CDC rules that apply to every dog, including returning pets and service dogs, with vaccination and documentation requirements that depend on where the dog has been. If your trip touches a country the CDC lists as high risk for rabies, check the current rules before you book anything.
The airline and the country are separate gates. Delta's policy decides whether your pet gets on the plane. The destination country decides whether it gets off at the other end, with its own rabies, microchip, and import-permit rules. Our entry rules guides cover the country-by-country requirements that Delta does not handle for you.
Most airlines carry cats and dogs and stop there. Delta goes one step further in the cabin, and it is worth spelling out because the searches around it are full of outdated answers.
If you have a bird and an international trip, Delta is a dead end for that leg. Plan the bird's travel separately, because no amount of paperwork changes the domestic-only rule.
Delta does not publish a strict pet weight limit for the cabin. The real limit is the under-seat kennel, so a heavy but compact cat and a light but bulky dog are judged the same way: can they fit and settle in the kennel under the seat. Where you sit is more tightly controlled.
Check the breed rules if your dog is snub-nosed. Delta applies breed restrictions to brachycephalic dogs and cats, like bulldogs, pugs, boxers, and Persians, because of the breathing risk. If your pet is one of these, or a mix, confirm directly with Delta before you book, since acceptance is not guaranteed.
This is the area that changed most, and older guides online still get it wrong. Since the 2021 update to federal air travel rules, the two categories are treated very differently.
If your animal provides comfort rather than trained tasks, plan and budget as a pet owner, not as a service animal handler.
You cannot add a pet online, and spots are capped per cabin and go first-come. Booking the pet is a separate step from booking your seat, and it has to happen by phone.
For a pet in the cabin, Delta charges $150 each way, per kennel, on flights within the US, Canada, Puerto Rico, and the US Virgin Islands. That is charged per direction, so a round trip runs about $300. International cabin travel, where it is allowed at all, costs $200 each way. The domestic fee rose from $95 in April 2025, so older guides quoting $95 are out of date. You pay at check-in, not online.
Small dogs, cats, and household birds can fly in the cabin, as long as they fit in a ventilated kennel that slides under the seat in front of you. Birds are the unusual part: Delta allows small household birds like parakeets and canaries, but only on domestic flights within the contiguous US, never on international routes. Anything too big for the cabin cannot travel with most civilian passengers.
Sometimes, but the list of exceptions is long. Cabin pets are allowed on many international routes only if you meet every document, health, age, and kennel rule, and Delta does not carry cabin pets to or from a long list of places including the UK, Ireland, Australia, New Zealand, Hong Kong, the UAE, South Africa, and others. Birds never fly internationally, and pets are not allowed in international premium cabins.
Delta recommends a soft-sided kennel of about 18 x 11 x 11 inches, but the real limit is the under-seat space on your specific aircraft, which is often lower than that. Some Delta jets have only about 9 inches of clearance, so a kennel that measures fine on paper can still fail to fit. Your pet must be able to stand up, turn around, and lie down inside, and the kennel is separate from your carry-on allowance.
Not for most people. As of 2026, Delta Cargo is not available to the general public for pet transport, and checked baggage in the hold is limited to active US military on PCS orders and State Department Foreign Service personnel. If your dog is too big for the cabin and you are a civilian, you cannot fly it on Delta, and you need a specialized pet shipper or a cargo-capable airline instead.
No, not as free service animals. Since the 2021 change to federal rules, Delta treats emotional support animals as pets. They pay the standard pet fee, must fit the cabin kennel rules, and follow every other pet restriction. Only fully trained service dogs fly free in the cabin, with the required DOT Service Animal Air Travel form.
Information on this page reflects the Delta Air Lines pet policy as of July 2026. Fees, kennel sizes, allowed routes, cargo availability, and breed rules are set by Delta and change over time, and destination entry rules are set by the CDC, USDA APHIS, and the country you are traveling to. Always confirm current requirements with Delta at delta.com before you book.
Delta is great for a small pet on a domestic route, and a dead end for a large dog or a bird going overseas. Fees, cabin limits, and cargo rules vary a lot by airline. Compare who will take your dog, cat, or bird on your route before you lock in dates.
