Where your plans allow, moving your outbound to a cheaper weekday can noticeably lower the total fare.
What is the cheapest time of day to fly to Bangkok?
Flights to Bangkok 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.

About flights to Bangkok
Overview
Bangkok is Thailand's electric capital and the gateway to South-East Asia — a city of glittering temples, floating markets, street-food stalls and buzzing nightlife. It is one of the most popular long-haul escapes for UK travellers, whether as a destination in its own right or a springboard to Thailand's islands and beaches. Nearly all flights arrive into the vast Suvarnabhumi Airport (BKK). Comparing fares in one place makes finding the right flight to Bangkok quick and simple.
Best time to fly to Bangkok
Bangkok is hot all year round. The cool, dry season from November to February is the most comfortable time to visit and the busiest, so fares run higher. The hot season peaks in April, and the monsoon brings heavy afternoon showers between roughly June and October — often a quieter, better-value time to fly. Check the price charts on this page for the cheapest dates.
Airlines and routes
Thai Airways and EVA Air fly direct from London Heathrow to Bangkok in around 11–12 hours. For connecting options — often better value — Emirates (via Dubai), Qatar Airways (via Doha), Etihad Airways (via Abu Dhabi), Singapore Airlines (via Singapore) and Turkish Airlines (via Istanbul) all serve Bangkok from the UK. From Manchester and other regional airports, a one-stop routing via a Gulf hub is the usual choice. Compare carriers for your exact dates to secure the lowest fare.
Things to do in Bangkok
Bangkok rewards visitors with a heady mix of culture, food and colour:
- Grand Palace & Wat Phra Kaew: the dazzling former royal residence and home of the Emerald Buddha.
- Wat Arun: the striking riverside Temple of Dawn, beautiful at sunset.
- Chatuchak Weekend Market: one of the world's largest markets, with thousands of stalls.
- Khao San Road: the legendary backpacker street, lively with food and music.
- Chao Phraya River: hop on a longtail boat or express ferry to see the city from the water.
At Suvarnabhumi Airport (BKK)
Suvarnabhumi sits about 30 km east of central Bangkok, with extensive duty-free shopping, currency exchange, ATMs and dining. The Airport Rail Link connects to the city's metro in around 30 minutes, while metered taxis and ride-hailing apps are plentiful. Bangkok's older Don Mueang Airport mainly handles budget and regional flights.
Top tips for finding cheap flights to Bangkok
- Book roughly 2–4 months ahead — long-haul fares to Thailand rise close to departure.
- Avoid the December–January peak; the green season brings noticeably lower prices.
- Be flexible with dates — midweek departures often beat weekend prices.
- Compare direct and one-stop options; a single Gulf-hub connection can save a good deal.
Travel essentials
- UK passport holders do not need a visa for tourist stays in Thailand of up to 60 days.
- The local currency is the Thai baht (THB).
- Carry light, breathable clothing and cover shoulders and knees when visiting temples.
Baggage & hand-luggage allowance for flights to Bangkok
Your allowance to Bangkok 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 |
Indicative only. Allowances vary by airline, route and fare — always check your airline's baggage policy.
Packing & baggage tips
- Full-service carriers (e.g. British Airways, Turkish Airlines, KLM) usually include a checked bag on long-haul economy fares; basic/low-cost fares often don't.
- Cabin (hand) bag size is commonly around 56 × 45 × 25 cm — confirm your airline's limit before you pack.
- Liquids in hand luggage must be in containers of 100 ml or less, inside one clear resealable bag.
- Weigh your bags at home — airport excess-baggage fees are far higher than pre-booked allowances.
- Extra or heavier bags are almost always cheaper added online in advance than at the airport.
