The most regular flights from Birmingham to Thailand travel to the bustling capital, Bangkok. KLM tend to offer the quickest route, via Amsterdam, which takes around 14 hours, but you can also fly with Swiss via Zurich and Emirates via Frankfurt in under 16.
If you're heading to the party hotspot of Phuket, Emirates can whisk you there in just under 17 hours with a stop en-route in Dubai, although you may prefer one of the cheaper two-stop services offered by Etihad and KLM which will only take a few hours longer.
Indirect flights are available to a host of destinations within the country, but can be costly, so it's worth considering booking a cheap flight to Bangkok and then arranging your own domestic onward flight with one of Thailand's budget airlines like Nok Air.
