Flights to Bangkok from the UK: Airline Route Schedules & Booking Guide

Flights to Bangkok from the UK land at Suvarnabhumi Airport (BKK). The fastest option is a nonstop flight of around 11 hours 30 minutes to 12 hours. Thai Airways and EVA Air fly from London Heathrow, and British Airways from London Gatwick. Regional travellers usually connect once via Dubai, Doha, Abu Dhabi, Istanbul or Amsterdam.

One-stop fares through Middle Eastern transit hubs can sometimes cost less than nonstop flights and serve far more UK airports. Fares vary by date, airline, departure airport and demand, so compare the total price, including baggage and connection time, rather than the headline fare.

TravelApp is a UK travel agency that helps travellers compare flights to Bangkok from the UK by airport, airline and date, and weigh flight-only fares against holiday packages.

Flights to Bangkok from the UK at a Glance

Bangkok is one of the best-connected long-haul destinations from the UK. Nonstop flights leave from London only, while one-stop flights connect most major UK airports to Suvarnabhumi Airport (BKK).

How to Secure the Cheapest Fares to Thailand

The best-value flights to Bangkok usually come from comparing nonstop and one-stop fares on the same dates, then checking the total price with baggage. No single airline or route is always the cheapest.

The main factors are:

• Nonstop vs one-stop. Indirect flight savings are possible via Gulf hubs, but the journey takes longer.

• Travel dates. High-season price spikes usually hit from December to February and during UK school holidays.

• Airport choice. Regional one-stop fares can beat the cost of travelling to London for a nonstop flight.

• Baggage. Most long-haul fares include checked bags, but allowances differ.

Which UK airport offers direct flights to Bangkok?

London Heathrow and London Gatwick are the only UK airports with direct flights to Bangkok. Thai Airways and EVA Air fly from Heathrow, and British Airways flies from Gatwick.

Heathrow has the most nonstop flights. Travellers outside London can compare flights from Manchester and flights from Birmingham, which connect once through a hub.

How far in advance should you book your flights to Thailand?

There is no guaranteed best time to book flights to Bangkok. As a general guide, booking around three to four months ahead gives good choice, and earlier is wise for Christmas, New Year and school holidays.

Keep in mind:

• Peak periods. December to February and UK school holidays sell quickly.

• Nonstop seats. Direct flights have fewer seats, so popular dates can fill early.

• Flexibility. Mid-week departures, such as Tuesdays and Wednesdays, are sometimes cheaper, but not always.

• Monitoring. Fares change as seats sell, so compare several dates.

Late deals do appear, but last-minute flight deals are less reliable during peak season.
