Hour Flights: The 7 Longest US Routes Flown By The Airbus A321neo In 2026

Hour Flights: The 7 Longest US Routes Flown By The Airbus A321neo in 2026 centers on how the Airbus A321neo is being used for near-maximum-length domestic sectors. Cirium data covering January through December 2026 shows American Airlines and Delta Air Lines operating the standard A321neo on seven US routes exceeding 2,300 nautical miles (4,260 km). The longest route reaches 2,643 nautical miles (4,894 km) with westbound block times approaching seven hours. Six of the seven routes are run exclusively by American, including multiple services linking its Phoenix hub to Hawaii and flights connecting Dallas/Fort Worth and Chicago to Anchorage. The seventh is a Miami–Seattle route jointly served by American and Delta. American schedules 370 flights annually each direction, while Delta operates 364 to 365. Westbound block times average about 6 hours 40 minutes, returning slightly faster due to jet-stream headwinds.
