Frequently asked

How many pets can I bring on Sun Country Airlines?
Sun Country Airlines allows 1 in the cabin, per passenger. Each pet needs its own carrier.
How much does it cost to fly a pet on Sun Country Airlines?

What if my flight is delayed past my health certificate validity?
If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
What happens if I forget a document?
At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
Sun Country charges 75 USD per direction for a cabin pet when the reservation is booked in advance. Budget 150 USD for a round trip. Add the pet to the reservation at booking to lock the advance rate. Pay the fee per direction, not once for the full itinerary. Reserve early, since cabin pet spots are capped per flight.
