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. Below: the official rules (cited), the honest under-seat caveat, and which carriers fit that limit.
📏 Short height: Height limit is only 9" — one of the tightest. Many standard 11"-tall carriers won't fit; choose a low-profile or flexible-height carrier. Sun Country notes the middle seat has the most under-seat space.

How to confirm your actual under-seat space
Sun Country Airlines'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 Sun Country Airlines to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
