Overview
Thailand is a firm favourite with UK travellers — a land of golden temples, tropical islands, buzzing markets and legendary food. From the energy of Bangkok to the beaches of Phuket and the cool hills of Chiang Mai, comparing every fare in one place makes finding the right flight quick and simple.
Best time to fly to Thailand
The cool, dry season from November to March is the most popular for the mainland and islands, with sunshine and comfortable temperatures. April and May are hot, while the June–October monsoon brings warm rain and lower prices. Fares peak over the Christmas and New Year period, so travelling either side of it can save a good deal. Check the price charts on this page for the cheapest dates.
Main gateway cities & airports
The main gateways are Bangkok Suvarnabhumi (BKK) and Don Mueang (DMK), with Phuket (HKT), Chiang Mai (CNX), Koh Samui (USM) and Krabi (KBV) ideal for beach and northern trips.
Airlines and routes
Thai Airways, British Airways and EVA Air fly direct from London to Bangkok in around 11–12 hours. For connecting options — often better value — Emirates, Qatar Airways, Etihad Airways, Singapore Airlines and Turkish Airlines all serve Thailand via their hubs. Comparing carriers for your exact dates is the surest way to secure the lowest fare.
