Delta Pet Policy 2026: In-Cabin Fees, Carrier Size and Route Limits

Travel · PetzDay Editorial · 2026-11-13

What Delta charges to fly a dog or cat in the cabin in 2026, the carrier size that fits, which seats and routes are excluded, and how to get the pet actually on your reservation.

Delta carries dogs, cats and household birds in the cabin on domestic flights for $150 each way, and the rule that gets people denied at the gate is not the fee — it is the carrier, the seat assignment, or the route. Delta sells cabin pets first-come, first-served within a per-flight limit, and Hawaii is excluded entirely.

This page is the operational version: what it costs, what fits under the seat, where pets are not allowed, and how to get the pet onto your reservation before you show up.

Delta pet fee in 2026

• Domestic (U.S., Canada, Puerto Rico, U.S. Virgin Islands): $150 each way, per carrier.
• International: typically $200 each way.
• Brazil: $200 each way.
• A round trip is two fees, and a connection on a separate ticket can add a third.

The fee buys the pet, not a seat. The carrier replaces your carry-on or personal item, there is no extra legroom, and you cannot buy the dog a seat for comfort.

Delta's in-cabin carrier size

Delta does not publish a single fleet-wide carrier dimension, which is the thing that trips people up. What it publishes is a recommendation and a rule:

• Recommended soft-sided maximum: 18 × 11 × 11 inches — the same number American and United use for soft bags.
• The actual limit is your aircraft's under-seat space, so Delta points you back to the seat in front of you rather than to a table.
• The carrier must be leak-proof, with ventilation on at least three sides domestically and four on international flights.
• The dog must fit inside and stay inside: stand, turn around and lie down without touching the sides.

A soft-sided bag compresses into uneven under-seat space and buys you an inch or two of usable height. If you are within half an inch of 18 × 11 × 11, size down — Delta's own wording makes the seat, not the bag, the authority.

Where Delta does not allow cabin pets

• Hawaii: no cabin pets to or from Hawaii, in either direction.
• Delta One and flat-bed seats: pets are not permitted.
• Exit rows, bulkhead rows and any seat without under-seat stowage: no room to stow the carrier, so no pet.
• International destinations: the U.K., Australia and New Zealand restrict cabin pets, and every destination adds its own import paperwork.

How to add a pet to a Delta reservation

1. Book the passenger ticket first. Delta requires a reservation before a pet can be added.
2. Reserve the pet by phone or chat, and get the confirmation in writing with the pet noted on the booking. Cabin pets are first-come, first-served within the per-flight limit, so this is a race, not a formality.
3. Check in at the counter, not at a kiosk. An agent inspects the carrier and collects the fee — budget extra time for this.
4. Security means the dog comes out of the bag. The carrier goes through the X-ray, the dog walks through with you on a leash.
5. Use a pet relief area after security, then board with your zone and put the carrier under the seat for taxi, takeoff and landing.

What Delta does not ask for, and what the state might

For a domestic cabin pet Delta does not require a health certificate or a rabies record. That is not the whole picture:

• The destination state can require documentation. USDA APHIS lists state-by-state requirements, and some states ask for a health certificate or proof of rabies vaccination.
• International travel always adds paperwork — an export health certificate endorsed by APHIS, plus the destination country's own rules.
• Coming back into the U.S. every dog needs a CDC Dog Import Form receipt, must be at least 6 months old and must have a scannable microchip.

The health certificate and vaccine guide covers the document side in full.

If the dog is too big for the cabin

Delta does not accept larger pets as checked baggage on ordinary tickets — they move through Delta Cargo. That means a hard-sided kennel that meets IATA-style requirements, a health certificate, a temperature-sensitive route, and a dog already comfortable in a crate for hours.

Alaska is the only one of the five largest U.S. airlines that still sells ordinary passengers space in the baggage compartment. The airline pet fee comparison lays out which carrier offers what.

Delta seat rows and cabin pets

Delta's narrowbody and widebody cabins differ enough that the same carrier can fit one aircraft and not another.

• Aisle and middle seats generally have the deepest under-seat stowage; window seats are often shallower because of the underseat life-vest box.
• Bulkhead and exit rows are excluded — there is no seat ahead to stow under.
• Delta One and flat-bed products are excluded outright.
• Regional aircraft have less space than mainline; if your itinerary has a Delta Connection leg, check that leg separately.

FAQ

How much is Delta's pet fee?

$150 each way within the U.S., Canada, Puerto Rico and the U.S. Virgin Islands, and typically $200 each way international. It is charged per direction, so a round trip with one dog is $300 domestic.

What carrier size does Delta allow in the cabin?

Delta recommends a soft-sided carrier no larger than 18 × 11 × 11 inches and does not publish a fleet-wide hard-sided limit. The binding constraint is the under-seat space on your specific aircraft, so measure the outside of the bag, including wheels and pockets.

Can my dog fly in the cabin to Hawaii on Delta?

No. Delta does not allow cabin pets to or from Hawaii. A larger dog would have to move through Delta Cargo, with the paperwork and temperature restrictions that involves.

Does Delta require a health certificate for a cabin pet?

Not for domestic cabin pets. Destination states can still require documentation, and any international trip adds an export certificate and the destination country's requirements. Returning to the U.S. always requires the CDC Dog Import Form receipt.

Can I bring two pets on Delta?

Yes, but each pet needs its own carrier and its own fee, and cabin pets are subject to the per-flight limit. Two carriers also means two under-seat spaces, which usually means two seats.

Is Delta pet-friendly compared with other airlines?

Delta is mid-pack: $150 each way is the same as American and United and more than Southwest ($125) and Alaska ($100), and the Hawaii exclusion is a real limitation. Alaska is the most permissive of the five, largely because it still sells hold space to ordinary passengers.
