While many airlines are increasing flight capacity to Europe next summer, Delta Air Lines is boosting service to a popular domestic destination: Alaska.

On June 8, 2025, the airline will bring back summer seasonal flights between its Salt Lake City International Airport (SLC) hub and Fairbanks International Airport (FAI) in Alaska, the gateway to Denali National Park. This five-hour flight will be operated on Delta’s Airbus A220-100, with the daily service running through Sep. 9, 2025. 

"I am excited to welcome Delta Air Lines' expanded summer seasonal service, now connecting Fairbanks to Salt Lake City and offering even more travel options for our community and visitors,” said Alaska International Airport’s director, Angie Spear, in a statement. "This new route enhances our connectivity and reaffirms Fairbanks' importance within Delta's network, building on the existing Seattle and Minneapolis routes.”

Tickets are already on sale directly on Delta’s website, starting at $264 one-way or 22,500 SkyMiles and $5.60 in taxes and fees.

In addition to Fairbanks, the airline will ramp up its connections to Anchorage. Just before the Memorial Day weekend, Delta will increase service to once daily from Detroit Metropolitan Wayne County Airport (DTW) and Anchorage International Airport (ANC). The seven-hour flight will be operated on Delta’s Boeing 757 aircraft. 

Around the same time, Delta will deploy its much larger Boeing 767-300ER with 226 seats between its mega-hub at Hartsfield-Jackson International Airport (ATL) and Anchorage International Airport (ANC). 

Delta isn't the only airline increasing flights to Alaska for the peak summer season, as there are now more travel options to the state than ever. This past summer, United Airlines launched its inaugural service from Dulles International Airport (IAD) to Anchorage (ANC) and will resume these popular flights for the upcoming peak season — when most of the state has up to 24 hours of sunlight.
