Revealed: The USA’s 18 Least-Served Domestic Widebody Routes

American Airlines , Delta Air Lines , Hawaiian Airlines , and United Airlines all have domestic US widebody flights between September and December 2024. Of course, the massive number of narrowbody flights means twin-aisle domestic links are comparatively unusual. Analyzing Cirium schedules shows that just one in every 128 domestic services will be on one.

The minimally served widebody markets

As of September 2, the latest information shows that 100+ domestic US airport pairs will have widebody flights between September and December. Of these, 18 have just one service scheduled, whether one roundtrip or a one-way flight. Other airport pairs only have two or three services, but they are not considered here.

Over half of the 18 links have one-way flights, which generally exist on/around October 26, the day before northern airlines switch to winter schedules based on IATA slot seasons. Aircraft are repositioned between hubs and allocated to passenger flights to earn revenue to offset the costs.

Boston to Los Angeles

Even though the 18 airport pairs have almost no twin-aisle services, many previously had regular or semiregular operations. Consider Boston to Los Angeles. Until 2012, American had a daily 767-300ER service (the oneworld carrier withdrew the type from its fleet during the pandemic).

Between 2013 and 2024, Boston-Los Angeles had only four flights (in that direction): November 18, 2022 (American 777-200ER); December 22, 2022 (American 777-200ER); January 8, 2024 (Delta 767-300ER); and March 24, 2024 (Delta 767-300ER).
