Which US cities have direct flights to Bangkok? As of September 26, 2026, no US city has a nonstop flight to Bangkok. The only direct service is United Airlines' daily Los Angeles to Bangkok flight, UA 820, which keeps one flight number but stops in Hong Kong on the way. United's San Francisco to Hong Kong flights connect onto it, and every other US to Bangkok trip involves a change of plane at a hub in Asia, the Middle East or elsewhere.
Because "direct" and "nonstop" mean different things when you book, this guide explains the difference, sets out what flies from each US gateway, and covers what to expect when you land.
| US city | Best option to Bangkok | Stop | Confirmed by |
|---|---|---|---|
| Los Angeles (LAX) | Direct: United UA 820, daily | Hong Kong (same flight number) | United newsroom, TAT, Hong Kong Airport records for September 25, 2026 |
| San Francisco (SFO) | One-stop connection on United | Hong Kong (change of flight) | United, TAT, Hong Kong Airport records |
| Washington, DC | One-stop on EVA Air | Taipei | TAT, June 2026 |
| Other US cities | One-stop via an airline hub | Asia, Middle East or elsewhere | Check the airline's own schedule |

Plan your trip
Are there nonstop flights from the US to Bangkok?
No. As of September 26, 2026, no airline flies nonstop between a US city and Bangkok. United's Los Angeles to Bangkok service, which the Tourism Authority of Thailand (TAT) described as the first US airline service to Bangkok since 2014, lands in Hong Kong on the way, and Thai Airways' winter 2026/27 network announcement adds no US routes.
What is the difference between a direct and a nonstop flight?
A nonstop flight does not land until it reaches its destination. Airlines use "direct" for a flight that keeps the same flight number from start to finish, even if it stops on the way. On a direct flight with a stop you normally stay with the same flight number, but the stop adds time on the ground and you may leave the aircraft.
When a search site labels a US to Bangkok itinerary as direct, open the details and check for a stop.
Which US city has a direct flight to Bangkok?
Los Angeles. United announced in April 2025 that it would start daily flights to Bangkok from Hong Kong, timed so that travelers from across North America could connect, and TAT reported that the first flight, UA 820 from Los Angeles via Hong Kong, arrived at Suvarnabhumi Airport on October 26, 2025. It uses a Boeing 787-9 Dreamliner with Polaris business class, Premium Plus and economy cabins.
We confirmed the route is still flying through Hong Kong International Airport's official flight records: on September 25, 2026, UA 820 departed Hong Kong for Bangkok, and UA 821 left Hong Kong for Los Angeles that evening. United's own website could not be reached for this check, so confirm the current schedule when you book.
Can you fly from San Francisco to Bangkok?
Yes, with a connection in Hong Kong. San Francisco has no through flight number to Bangkok, but United flies San Francisco to Hong Kong, and both United and TAT describe the Hong Kong to Bangkok flight as timed to connect with those services. Hong Kong's flight records for September 25, 2026 show United flights departing for San Francisco.
Because this is a connection rather than a through flight, allow for the transfer when you compare total travel times.
How do you fly to Bangkok from other US cities?
From every other US city, the practical choice is a one-stop itinerary through an airline hub: United via Los Angeles, San Francisco and Hong Kong, or an Asian or Middle Eastern airline connecting through its home airport. In June 2026, TAT welcomed EVA Air's Washington, DC to Taipei service as strengthening one-stop North American access to Bangkok.
North of the border, TAT notes that Air Canada flies nonstop between Vancouver and Bangkok, which some West Coast travelers use as an alternative. Airlines add and drop long-haul routes often, so treat any list of "direct" US to Bangkok routes with care unless it links to the airline's own schedule. For a comparison from Europe, see which airlines fly direct to Bangkok from London.
Which Bangkok airport do flights from the US arrive at?
United's Bangkok flights land at Suvarnabhumi Airport (BKK), east of the city center in neighboring Samut Prakan province. Bangkok's other airport, Don Mueang, is used by many low-cost airlines; our guide to which Bangkok airport is better explains the difference.
The Airport Rail Link runs from Suvarnabhumi into the city, and taxis and hotel cars are the alternative with luggage; see how to get from Bangkok airport to the city. Before you fly, check the entry rules in our guides to the Thailand Digital Arrival Card and how long you can stay in Bangkok. Klook sells a Thailand eSIM you can set up before the flight.
Where should you stay after a long flight?
After a trans-Pacific flight, many travelers choose a hotel close to a rail line for the first night. Our Bangkok hotels guide covers the options from the river to Siam, and Anantara Siam Bangkok Hotel is one of the luxury hotels that can arrange airport pickups.
With a late-morning arrival, keep the first afternoon gentle: Lumphini Park is a green space for a walk to shake off the flight, and the temples of the Old City, including the Grand Palace and Wat Arun, are better saved for a morning. Our Bangkok attractions guide helps plan the rest.
