Delta Air Lines pet policy

Pets in the cabin

Allowed

“On domestic flights within the contiguous U.S., small dogs, cats and household birds that meet the age, health, size and kennel requirements can travel in the cabin for a one-way fee that is collected at check-in.”

From Delta Air Lines’s website, checked 21 Oct 2026

Under-seat carrier, maximum

Not published

“The maximum in-cabin kennel dimensions are determined by the aircraft dimensions of your flight, as the under-seat space varies by aircraft.”

Delta publishes no fleet-wide maximum. It recommends a soft-sided kennel of 18 x 11 x 11 in, which it says fits most (not all) aircraft types.

Soft-sided carrier, maximum

Not published

“Delta recommends a soft-sided kennel with maximum dimensions of 18” x 11” x 11” since this fits most aircraft types.”

18 x 11 x 11 in is a recommendation that fits most aircraft, not a guaranteed maximum, so it is not stored as a value.

Not stated; Delta's in-cabin kennel rules describe soft-sided kennels only.

Pet must stand and turn around

Yes

“Your pet must be small enough to fit comfortably in a kennel with the ability to move around without touching or sticking out from the sides.”

Delta's wording is 'move around without touching or sticking out from the sides', not 'stand and turn'.

Breed restrictions

Brachycephalic (snub-nosed) dogs, cats and their mixes are not permitted (stated in Delta's cargo section).

“Brachycephalic (snub-nosed) dogs, cats and their mixes are not permitted on Delta or Delta Connection flights.”

Appears under 'Shipping Your Pet' (cargo). Read literally it bans these breeds from all Delta flights; the in-cabin page states no breed limit.
