en.Wedoany.com Reported - In 2026, American Airlines and Delta Air Lines will operate seven U.S. domestic routes exceeding 2,300 nautical miles (4,260 kilometers) using the standard Airbus A321neo. According to Cirium data, American Airlines and Delta Air Lines jointly operate seven routes, with the longest being Dallas/Fort Worth to Anchorage at 2,643 nautical miles (4,894 kilometers), with a westbound flight time of nearly seven hours.

Of these seven routes, six are exclusively operated by American Airlines, including four connecting its Phoenix hub to Hawaii, and two linking the Dallas/Fort Worth and Chicago hubs to Anchorage. The seventh is a transcontinental route from Miami to Seattle, jointly operated by American Airlines and Delta Air Lines.

The Miami to Seattle route spans 2,367 nautical miles (4,384 kilometers). American Airlines plans 370 flights in each direction, while Delta Air Lines will operate 364 to 365 flights. The westbound flight time is approximately 6 hours and 40 minutes, with the eastbound return taking about 6 hours, a difference primarily due to prevailing high-altitude headwinds. This route connects cities on opposite ends of the continent and holds hub value for both airlines. American Airlines' Miami hub covers the Caribbean and Latin America, while Delta Air Lines' Seattle hub connects to the Asia-Pacific market.

The Phoenix to Kahului (Maui) route spans 2,472 nautical miles (4,579 kilometers). American Airlines plans 538 flights in each direction, making it the highest-frequency route on this list. Westbound flight times range from approximately 6 hours and 30 minutes to 6 hours and 50 minutes, with eastbound returns taking about 5 hours and 30 minutes to 5 hours and 45 minutes. This is American Airlines' busiest Hawaii A321neo route, with up to two daily flights, reflecting year-round leisure demand.

The Chicago O'Hare to Anchorage route spans 2,473 nautical miles (4,580 kilometers). American Airlines operates the A321neo seasonally, planning 137 flights in each direction for 2026. This service runs daily during the summer, replacing the Boeing 737 MAX 8 used in shoulder seasons. Westbound flight time is approximately 6 hours and 50 minutes, while the eastbound return is a red-eye flight lasting about 6 hours and 15 minutes. This route primarily serves the leisure market, with Anchorage acting as a gateway to Alaska tourism.

The Phoenix to Kona route spans 2,485 nautical miles (4,603 kilometers). American Airlines is the only operator offering direct service, planning 384 flights in each direction for 2026. Westbound flight times range from approximately 6 hours and 35 minutes to 6 hours and 50 minutes, with eastbound returns taking about 5 hours and 50 minutes to 6 hours. This route operates daily, with a second frequency added during peak travel periods. Kona Airport's runway is 11,000 feet (3,353 meters) long, sufficient to support A321neo operations on this route.

The Phoenix to Honolulu route spans 2,535 nautical miles (4,696 kilometers). American Airlines plans 515 flights in each direction, tying with the Kahului route for the highest frequency. Average westbound flight time is approximately 6 hours and 40 minutes to 6 hours and 50 minutes, with eastbound returns taking about 5 hours and 55 minutes to 6 hours. Honolulu is Hawaii's largest aviation market, and Daniel K. Inouye International Airport serves as a hub for inter-island flights, allowing this route to connect not only to Oahu but also to other islands via transfers.

The Phoenix to Lihue (Kauai) route spans 2,589 nautical miles (4,796 kilometers). American Airlines is the only operator offering direct service, planning 385 flights in each direction for 2026. Westbound flight times range from approximately 6 hours and 45 minutes to 7 hours, with eastbound returns taking about 6 hours. Kauai attracts couples and outdoor travelers, and this route operates one daily flight, reflecting stable but not deep demand. Lihue Airport's single runway is 6,500 feet (1,981 meters) long, sufficient for operations.

The Dallas/Fort Worth to Anchorage route spans 2,643 nautical miles (4,894 kilometers), making it the longest A321neo route within the United States in 2026. American Airlines is the only operator offering direct service, planning 400 flights in each direction for the full year. Westbound flight times range from approximately 6 hours and 50 minutes to 7 hours and 10 minutes, with eastbound returns taking about 6 hours and 30 minutes to 6 hours and 40 minutes. This route connects American Airlines' largest hub with Alaska's largest city, primarily covering the peak summer travel season, but year-round scheduling indicates service extends beyond the core peak period.
