Airlines That Allow Large Dogs in the Cabin (2026)

None of the 24 airlines we track lets a large dog ride in the cabin as a pet. Every airline that takes pets in the cabin requires your dog to fit in a carrier under the seat in front of you. The most room you can get is 22 × 16 × 10 in on Air Canada (Regional aircraft). For a bigger dog, Aeromexico, Air Canada, Air France, Alaska & Hawaiian Airlines, American Airlines, Avianca, British Airways, Emirates, Iberia, KLM, LATAM Airlines, Lufthansa, Qatar Airways, Turkish Airlines, Volaris and WestJet offer a way to fly in the hold.

Most room in the cabin, ranked

The biggest carrier each airline allows, from roomiest to tightest. A bigger carrier means a slightly bigger dog can fit, but the dog still has to fit under the seat.

How to check if your dog will fit

  1. Find your airline's maximum carrier size in the ranking above. The sizes are the most the airline allows, not a guarantee for every seat.
  2. Measure the carrier you plan to use from the outside, with it fully closed, and compare all three sides.
  3. Let your dog settle inside the closed carrier at home. If it can't lie down and turn around comfortably, it's too small for the cabin.
  4. Read your airline's page for its carrier-type and seat rules before you buy a carrier.

What about emotional support dogs?

Alaska, American, British, Delta, Southwest, United treat emotional support animals as regular pets. The same carrier size rules and pet fees apply. Trained service dogs follow separate rules, which are on each airline's page.

Built from each airline's official pages. Rules change, so confirm with your airline before you book. Full details and sources are on each airline page.
