Sun Country Airlines in-cabin pet policy — and the carriers that fit
Sun Country Airlines allows small pets in the cabin in a carrier up to 17 × 12 × 9 in, stowed under the seat in front of you. Already own a carrier? Enter its measurements below to check it against this limit. The in-cabin fee is $75 each way (booked in advance) or $100 walk-up. 2 of the 15 carriers we track clear that published limit.
The Sherpa Original Deluxe (Small) leaves the most room — 0.5" on its tightest dimension, while the Mr. Peanut's Gold Series Mini (Low-Profile) only just squeaks in with nothing to spare. Sun Country's 9" height ceiling sits mid-pack among the 77 airlines we track (shared with Condor, TAP Air Portugal): Aegean, Air Europa, Air France and Air Transat allow more, while EL AL Israel allows only 7".

This table ranks by Sun Country Airlines’s size limit — not by your pet. The weight under each carrier is what that size is rated to hold. A bag can clear the airline and still be the wrong size for the animal, which is the most common reason one goes back — measure your pet first →

How to confirm your actual under-seat space
Sun Country Airlines's number is its published maximum, not a guarantee 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 exit rows — bulkheads have no under-seat storage and most airlines ban pets there — and check this airline's seat rules above.
- Call Sun Country Airlines to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
