United Airlines expands Maine to California routes for 2027
Portland International Jetport will see increased service to San Francisco and Los Angeles starting next year.
By Riya Zhao ·
United Airlines is increasing its flight schedule between Portland, Maine, and two major cities in California. The carrier will add 20 new round-trip flights to the West Coast, expanding service that was initially limited to Saturdays.
The airport announced the addition on Monday. This follows an initial announcement in January of 2026, which established Saturday-only service between Portland International Jetport and San Francisco and Los Angeles for the summer season. The new flights build on that foundation, introducing mid-week departures.
Service to San Francisco will begin on May 8, 2027, with flights operating on Saturdays. On June 23, 2027, United will add Wednesday departures to that route. Service to Los Angeles starts later, on June 26, 2027, with Saturday flights. An additional six Wednesday flights will operate during the peak summer travel period.
Zach Sundquist, assistant director of the jetport, stated that these routes facilitate movement between the East and West Coasts. He noted that United’s hubs in San Francisco and Los Angeles provide one-stop connections to Pacific Rim destinations. Sundquist said the new Wednesday service makes these options more appealing to local businesses with ties to Asia.
The expansion will bring the total count of United flights from Portland to San Francisco to 32. Flights to Los Angeles will reach 19. Portland International Jetport is the busiest airport in Maine. It recorded nearly 2.6 million passengers in 2025, up from 2.4 million in 2024.
Through August of the current year, the airport has handled more than 1.7 million passengers. The added frequency aims to capture this growing volume of travelers seeking direct links to the West Coast.
