A large majority of the world’s remaining scheduled passenger Boeing 757 flights in September are operated to, from, or within the United States. Data from ch-aviation shows Delta Air Lines currently operates 102 Boeing 757 aircraft, while United Airlines has a fleet of 61. Both airlines utilize the -200 and -300 variants. Icelandair also continues to operate its 757-200s on routes to the US.
The Boeing 757 is less fuel-efficient and requires more maintenance compared to newer aircraft models. However, these older jets may be less costly for airlines since they are often paid off or available at low lease rates. Despite this advantage, airlines have been reducing their use of the type as more efficient alternatives become available. According to OAG data, US 757 flights have dropped by almost 20% compared with last September.
An analysis of scheduled passenger flights for September reveals that there are 114 routes served by the Boeing 757 in the US—83 domestic and 31 international. Among international routes, Delta operates flights from Detroit and Minneapolis to Keflavik, while United offers service between Washington Dulles and Dublin with two daily departures.
