Sun Country is a U.S. leisure airline serving domestic vacation destinations and markets in Mexico, Central America and the Caribbean. Allegiant completed its acquisition on 13 May 2026, while Sun Country continues to accept bookings and operate under its own brand during the integration. Its passenger tickets and rewards remain separate from Allegiant's.
Choose your aircraft to explore the Sun Country seat maps listed below.
Yes. Buy a preferred seat during booking or add selection later through Manage Your Trip, subject to availability. You can also skip selection and receive an assigned seat at check-in. Sun Country sells Standard, Exit Row and Best Seat options; passengers sitting at an exit must be willing to help in an emergency.
No. Existing Sun Country reservations remain valid, and you should continue using Sun Country's booking and service channels. Tickets issued by either airline are currently valid only on that airline. Their rewards balances cannot be combined or used interchangeably while the programmes remain separate.
The base fare includes one underseat personal item up to 17 × 13 × 9 inches. An overhead cabin bag is a paid option unless included in your bundle: maximum 24 × 16 × 11 inches and 35 lb, including wheels and handles. Oversized items must be checked and applicable fees paid.
Small cats and dogs weighing up to 35 lb may travel for a non-refundable fee, subject to capacity. International flights, Anchorage, Hawaii and Puerto Rico services are excluded, as is interline travel. Call Reservations to arrange transport. One pet per carrier is allowed; the carrier must be no larger than 17 × 12 × 9 inches, ventilated and leakproof, and allow the animal to stand and move. It counts towards your carry-on allowance and must remain closed under the seat. Bulkhead and exit seating are unavailable. Recognised service animals have separate rules.
