| Don Mueang | DMK | Bangkok | Budget airlines, domestic |

Tips for Long-Haul Flights to Thailand
- Book layovers of 2–4 hours — enough time to connect comfortably without excessive waiting
- Avoid double connections unless the savings are substantial — each stop adds fatigue and delay risk
- Consider a stopover — many airlines let you spend 1–2 days in the layover city (Tokyo, Seoul, Singapore) at no extra airfare
- Fly overnight from the US — most departures leave in the late morning or afternoon and arrive in Asia the next evening, aligning with Thai time
- Time zone difference: Thailand is GMT+7 (12–15 hours ahead of US time zones). Jet lag is significant
- Visa: US citizens get 30 days visa-free on arrival for tourism
