Southern Airways Express pet policy — what it publishes, and what it does not
Southern Airways Express accepts pets in the cabin but does not publish a maximum carrier size, so we will not compute a fit rather than guess one. The in-cabin fee is $35 service fee per animal, per direction (up to two small animals with a combined weight of 25 lbs. or less in the same carrier). Confirm the under-seat allowance with Southern Airways Express before you book.
That means nothing on our list fits, and nothing comes close enough to squeeze in either — at not published this is one of the tightest allowances we track. Check Southern Airways Express's own policy for cargo or an approved pet-shipper option before you book. Southern Airways Express does not publish a maximum carrier height, so there is nothing to compare against the other airlines we track. Confirm the under-seat allowance directly with Southern Airways Express.

How to confirm your actual under-seat space
Southern Airways Express's number is a fleet-wide recommendation, not a promise for your exact seat. Before you buy or fly:
- Check which aircraft operates your flight (in your booking or on a seat-map site).
- Avoid bulkhead and some window seats — they have less (or no) under-seat storage.
- Call Southern Airways Express to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.

Common questions
What size pet carrier does Southern Airways Express allow in the cabin?
Southern Airways Express's recommended maximum in-cabin carrier is not published. It must fit fully under the seat in front of you. Source: the Southern Airways Express pet policy.
How much does Southern Airways Express charge for an in-cabin pet?
$35 service fee per animal, per direction (up to two small animals with a combined weight of 25 lbs. or less in the same carrier). Always confirm the current fee on the official Southern Airways Express pet page before you fly.
Which pet carriers fit Southern Airways Express?
No carrier we track clears Southern Airways Express's published not published outright, and none compresses down far enough either — check Southern Airways Express's cargo or approved pet-shipper options. Full shortlist: /fits/southern-airways-express/.
Is Southern Airways Express's not published limit guaranteed on every aircraft?
No. Southern publishes no under-seat carrier dimensions. Instead it defines placement: "Small pets must be able to fit on the floor at the passenger's feet (always during takeoffs and landings), or comfortably on the passenger's lap without spilling onto the aisle; the maximum combined weight of any pet at the passenger's seat is 15 lbs." The only kennel dimension in the Contract of Carriage — "The maximum size for any kennel/crate used to transport a pet is 40\" l x 27\" w x 30\" h" — applies to a pet occupying its OWN purchased bench seat, NOT to under-seat stowage, so it is deliberately NOT recorded as a carrier limit. The document also states the number of pets per flight depends on size, with pilot discretion. Neither owner nor pet may occupy the last row behind the boarding door or emergency exit seats. Treat the published figure as a fleet-wide maximum, not a promise for your seat, and prefer a collapsible or flexible-height carrier.
How many pets can I bring in the cabin on Southern Airways Express?
Generally two pets per flight; the Contract of Carriage states the number of pets allowed on each flight is also based on size, with exceptions at pilot discretion. Species accepted: domesticated dogs, cats. Weight limit: 15 lb maximum combined weight of any pet at the passenger's seat; up to two small animals with a combined weight of 25 lbs. or less may share one carrier.
