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. The in-cabin fee is $75 each way (booked in advance) or $100 walk-up. 1 of the 15 carriers we track clears that published limit.
The Sherpa Original Deluxe (Small) is the one that clears it, with 0.5" to spare on its tightest dimension. Sun Country's 9" height ceiling sits mid-pack among the 17 airlines we track: Delta, American, United and Alaska allow more, while Air Canada allows only 8".

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.
