The US Department of Transportation’s all-carrier international market records for January–July 2026 show Los Angeles–Bangkok as the only US–Thailand scheduled passenger market carrying passengers under one flight number. This includes services with intermediate stops and does not mean nonstop. Cargo, non-scheduled passenger flights and a Honolulu record with zero passengers are excluded from the regular-flight list. These historical records do not guarantee which routes will operate on a future travel date.
