Due to its isolated location in the far northwest of the North American continent, Alaska is home to some seriously long domestic flights. This month alone, current scheduling data made available by Cirium, an aviation analytics company there are two non-stop internal routes longer than 3,000 miles (4,828 km) originating in the state. These connect the ‘Last Frontier’ to some of the largest and busiest hubs in the United States.
In this article, we will dive deeper into the data to take a closer look at the longest non-stop US domestic flights that originate in the federal state of Alaska this December. In addition to examining their frequencies, we will also analyze the airlines and aircraft operating them, and their typical block times.
Delta Air Lines To Atlanta
Cirium’s data shows that, in December 2025, the longest non-stop US domestic flight from Alaska connects Anchorage (ANC) with Atlanta (ATL). This Georgia-bound route clocks in at a mighty length of 3,416 miles (5,497.5 km), and is served exclusively by Delta Air Lines. The SkyTeam founding member uses 
Boeing 767-300ER widebody twinjets on this route, with aeroLOPA showing that they have 216 seats across three classes.
This month, Delta has scheduled 12 flights each way between Atlanta and Anchorage, initially operating weekly before a rise to as many as five flights a week towards the end of the month. Flying from Atlanta to Anchorage, passengers can expect a block time of seven hours and 42 minutes, and seven hours and three minutes going back to Atlanta. This route was extended into the winter season in 2025, as Anchorage Airport explains:
“Previously operating only during the summer, this extension will provide travelers with more options to connect between Anchorage and the southeastern US, including increased availability during the holiday season.”
American Airlines To Dallas/Fort Worth
Elsewhere in the United States, American Airlines’ corridor from Anchorage to Dallas / Fort Worth clocks in at a distance of 3,042 miles (4,895.6 km). In contrast to its SkyTeam rival’s Boeing widebody usage, the oneworld founding member favors Airbus narrowbodies on this route, namely in the form of the Airbus A321neo. These next-generation single-aisle twinjets have 20 domestic first class and 176 economy class seats on board.
As far as frequency is concerned, American Airlines has scheduled 16 flights in each direction between Anchorage and Dallas / Fort Worth this month. Curiously, these services have a rather uneven spread, with a daily round trip on December 1 and 2, but then nothing until December 18. At that point, the daily frequency will resume for the rest of December, with American Airlines offering a grand total of 3,136 seats each way on the route this month.
Passengers flying with American Airlines from Dallas / Fort Worth to Anchorage can expect a block time of seven hours and 12 minutes, with flight AA2572 leaving Texas at 3:04 pm and landing in Alaska at 7:16 pm local time. Just over an hour later, the return leg departs under the same flight number at 8:21 pm, and, after an overnight journey lasting six hours and 37 minutes, is scheduled to land in Texas at 5:58 am local time.
The Ten Longest Domestic Airbus A321neo Routes In The US
American Airlines, which currently has the largest fleet, has seven of the top ten routes.
Two More Routes Exceed The 2,800-Mile Mark
Moving down in distance, there are also two non-stop US domestic routes between 2,800 and 3,000 miles long originating in Alaska this month. The longer of the pair is operated by the state’s own Alaska Airlines using the 737 MAX 9, and connects Anchorage with Kona (KOA) in Hawaii, some 2,874 miles (4,625 km) away. The carrier has scheduled 13 flights in each direction this month, amounting to a weekly schedule of three rotations.
Last but not least, 
United Airlines operates non-stop flights from Anchorage to Chicago O’Hare (ORD) using the Boeing 737 MAX 8. This route is 2,846 miles (4,580 km) long, and will see 15 rotations this month. After a round trip on December 1, the route will pause before resuming on December 18.
