Sun Country Airlines: Flight Schedules, Baggage Rules & Travel Guide

Sun Country Airlines is a low-cost carrier located in the state of Minnesota which provides scheduled passenger, charter customers and cargo operations. Its network includes destinations across the United States, Mexico, Canada, Central America and the Caribbean. Sun Country continues to operate under its own name for now, while the two airlines move toward a future operational integration.

Travelers can book flights, select optional services, check baggage requirements and manage eligible trips through Sun Country's digital channels.

Sun Country uses a flexible operating model that allows its scheduled network to change according to travel demand and seasonal patterns.

Sun Country doesn’t operate all year round on all routes. It has parts of its schedule at different times of the year. Its 2026 and 2027 schedules include more seasonal flying to leisure destinations.

For winter and spring 2027, the airline announced increased service to Fort Myers, Orlando, Las Vegas and Phoenix. It also planned additional flights to Cancun, Mazatlán and Puerto Vallarta. Service to Minneapolis and Montego Bay and to Minneapolis and Melbourne, Florida, is expected to return, as is seasonal Duluth-Fort Myers service.

Schedules are seasonal so travellers should check for available flights for their specific dates prior to booking.

Sun Country has many flights and optional services for passengers to use that meet their needs as travellers. The airline allows passengers to choose available flights and book additional services like baggage and seat selection while booking.

When making a booking:

Sun Country has set specific size and weight limits for different kinds of baggage.

Before you go to the airport, check the size and weight of your bag so you don’t get any baggage surprises.

Sun Country's mobile app provides check-in, boarding-pass and flight-status functions. The airline now allows passengers to check in on the app from 24 hours before scheduled departure to one hour before.

On travel day, keep your identification or passport available and make sure your baggage meets the applicable requirements. You can also check flight status before heading to the airport to keep abreast of changes to your flight.
