United Airlines plans longest Boeing 757 flights from May to December 2025

Another focus is United’s route from Washington Dulles to Edinburgh, which has transitioned to a year-round service. The Scottish capital has recently benefitted from increased transatlantic capacity, supported by Visit Scotland incentives and its growing recognition internationally. "The Scottish capital has seen substantial transatlantic capacity increases recently," influencing United's decision to expand the route.

Additionally, United’s domestic operations with the 757-300 variant focus on high-capacity flights rather than long-haul, reflecting a different strategic utilization compared to the 757-200. One of the longest domestic routes for the 757-300 will be from San Francisco to Fort Lauderdale, covering 2,245 nautical miles (4,158 km). It's the first time United will operate this variant on the route, with limited departures planned during the summer peak.

With varying usage between its 757-200s and 757-300s, United’s strategic approach maximizes the advantages of these aircraft types within their capacity and cost frameworks. As it navigates through different seasonal demands, United continues to leverage its extensive fleet for efficient and effective route management.
