Return flights from London to Thailand typically cost between £577 and £701 in August, though fares move with demand, season and how early you book. The lowest fare our search found recently was £386 — a great price and well below the usual range, so a price near this is worth grabbing. Keeping your dates flexible and comparing nearby days is the easiest way to land at the cheaper end.
The cheapest day to depart to Thailand is usually Saturday, when fares start from around £456 — midweek departures tend to be quieter and cheaper. Thursday is typically the most expensive day to fly out (around £577), as weekend travel is popular with leisure and business travellers alike. Where your plans allow, moving your outbound to a cheaper weekday can noticeably lower the total fare.
Flights to Thailand are generally cheapest departing in midday, with fares from around £386. Departures in the afternoon tend to cost more (about £567), as those slots are more convenient and in higher demand. Picking an off-peak departure time is a simple way to trim the price without changing your dates.
The cheapest return flights to Thailand depart from London Heathrow (LHR), from around £514. London has several airports serving this route and fares can vary between them — Stansted (STN) is often the priciest at around £626. It's worth checking which London airport is both cheapest and most convenient for you before booking.
The cheapest month to fly from London to Thailand is typically November, with return economy fares from £386. Fares are usually highest in December (around £839). Figures are indicative, from sampled live fares, and change with demand.

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.
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.
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.
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.
Your allowance to Thailand depends on the airline and the fare you book. The table below shows typical long-haul allowances so you know roughly what to expect — always confirm the exact limits with your airline before you fly.
| Fare type | Hand baggage | Checked baggage |
|---|---|---|
| Basic / Light economy | 1 small under-seat bag | Usually none — add for a fee |
| Standard economy | 1 cabin bag + 1 personal item | Typically 1 × 23 kg |
| Premium economy | 1–2 cabin bags + personal item | Typically 2 × 23 kg |
| Business / First | 2 cabin bags + personal item | Typically 2 × 32 kg |
