KAYAK’s top tips for finding a cheap flight from Chiang Mai to London Heathrow Airport

  • If you need special assistance on this route, make sure to contact your airline at least 48 hours in advance. As there are some self-transfer routes with multiple airlines, check to see if you need to contact both airlines.
  • While there are many flights from Chiang Mai to London Heathrow Airport (LHR) with a single stopover, you can also find flights with two stopovers that are cheaper. Most stop in Bangkok (BKK) first. Oman Air flights then stop in Muscat and Etihad Airways flights stop in Abu Dhabi (AUH). Bangkok Airways and Austrian Airlines partner for a route that stops in Bangkok and Vienna (VIE)
  • After landing at London Heathrow Airport, you can head into Central London on the Heathrow Express. It takes around 15 minutes to arrive at London Paddington Station. Alternatively, you can take the Elizabeth Line train which takes slightly longer but is also cheaper.
  • If you fly with Emirates or Qatar Airways, you can use their stopover services on your second stopover in Dubai (DXB) or Doha (DOH). This service includes a stay at a luxury hotel and optional tours. If you have to book a long stopover with Emirates, you may be able to access this service for free.
  • If you have a stopover in Bangkok, make sure you check your ticket carefully. Some of these flights may depart from the Domestic Terminal in Chiang Mai, instead of the international one. This may also mean you'll need to go through a security check when you enter the International Terminal in Bangkok.
