United Airlines highlights longest nonstop routes operated by Boeing 737 MAX in upcoming year

United also connects Anchorage with several other hubs using the same aircraft model. Its Washington-Dulles to Anchorage route is nearly as long at about 2,916 nautical miles (5,400 kilometers). Additional seasonal services link Houston (2,837 NM/5,254 KM) and Chicago (2,473 NM/4,580 KM) to Anchorage. Routes from Denver and San Francisco are shorter by comparison.

Fairbanks is another key Alaskan destination served by United during peak seasons. Flights from Chicago-O’Hare to Fairbanks cover around 2,420 nautical miles (4,482 kilometers), ranking among United’s top ten longest routes for the type.

In Latin America and transatlantic markets, United deploys the Boeing 737 MAX on several lengthy services out of San Francisco. Notably, flights to Panama City span about 2,885 nautical miles (5,343 kilometers), while services to San Jose and Liberia in Costa Rica reach distances up to roughly 2,640 NM (4,891 KM) and 2,560 NM (4,741 KM), respectively.

A unique operation in United’s network is its transatlantic route from Newark to Funchal in Madeira (Portugal). Using a Boeing 737 MAX 8 three times weekly during summer seasons since June this year—and returning for summer next year—this flight covers approximately 2,761 NM (5,114 KM).

Houston George Bush Intercontinental Airport remains a central hub for United’s Caribbean and South American operations due to ETOPS certification across its entire Boeing narrowbody fleet. The Houston–Georgetown (Guyana) route measures about 2,521 NM (4,669 KM) and runs four times per week.

Other U.S. carriers also operate similar long-range flights with their own fleets; American Airlines runs daily Miami–Georgetown services using the same aircraft type.

United configures its Boeing 737 MAX 8s with seating for up to 166 passengers across first class and economy cabins. These jets were also first in United’s lineup to feature updated interiors including seatback screens and larger overhead bins—a move aimed at enhancing passenger comfort on longer journeys.

Overall data shows that most of these extended routes utilize the smaller but more numerous MAX 8 variant rather than the higher-capacity MAX 9 or upcoming MAX 10 models. According to industry analysis from Cirium’s databases—widely used by airlines for planning purposes—these deployments allow United Airlines to balance demand while optimizing operational efficiency on some of its lengthiest narrowbody flights worldwide.
