United Airlines is once again strengthening its position as the leading U.S. carrier across the Pacific with a major route expansion, adding four new routes to Asia and Australia. Beginning this fall, travelers will gain access to Bangkok, Ho Chi Minh City, Adelaide, and a second daily flight to Manila, all part of United’s ongoing strategy to offer the most extensive international network of any U.S. airline.

With these additions, United will fly to 32 destinations across the Pacific, offering more than four times the number of routes than any other U.S. carrier. If you’re dreaming of an Asian adventure or an Aussie summer getaway, now is the time to start planning—and set alerts with AwardFares to track award space the moment it becomes available.

United Airlines Winter 2025 Routes (Pacific Expansion): Nonstop Flights to Bangkok, Ho Chi Minh City, Adelaide, and Manila.

New Daily Flights to Bangkok and Ho Chi Minh City

United will be the only U.S. airline offering flights to both Bangkok, Thailand, and Ho Chi Minh City, Vietnam starting October 26, 2025. These flights will operate daily from Hong Kong, enabling seamless one-stop connections from Los Angeles (LAX) and San Francisco (SFO).

Bangkok, Thailand

Bangkok is a city that blends tradition and modernity. From the sacred Wat Phra Kaew and bustling night markets to the iconic tuk-tuk rides and sizzling street food, it’s a sensory overload that travelers can now enjoy with MileagePlus miles. Flights will be operated by United’s Boeing 787-9 Dreamliner.

Ho Chi Minh City, Vietnam

Also launching on October 26, United’s new daily service to Ho Chi Minh City offers travelers a chance to dive into the cultural heart of Vietnam. Expect French colonial architecture, vibrant street food (think pho, banh mi, and Vietnamese iced coffee), and a dynamic local scene. This route also utilizes the 787-9 Dreamliner, ensuring a comfortable long-haul journey.

First-Ever Nonstop Flights to Adelaide, Australia

Starting December 11, 2025, United will be the first airline to offer nonstop service between the U.S. and Adelaide, Australia. Flights will operate three times per week from San Francisco (SFO) on a Boeing 787-9 Dreamliner. This seasonal route positions United as the only U.S. airline serving four major cities in Australia: Sydney, Melbourne, Brisbane, and now Adelaide.

Adelaide, Australia

Travelers to Adelaide can enjoy the stunning landscapes of Kangaroo Island, taste their way through Barossa Valley and McLaren Vale wine regions, and explore the famed Adelaide Central Market—home to more than 70 local food vendors. It’s the perfect warm-weather escape for Northern Hemisphere travelers looking to trade winter for summer Down Under.

This new frequency gives travelers daytime and evening options in both directions, adding more flexibility for business and leisure travelers alike.

Manila, Philippines

Planning a day trip? Head to Tagaytay for scenic views of Taal Volcano—a volcanic island within a lake on an island.
