About flights to Thailand
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.
Popular places to visit in Thailand
- Bangkok: the Grand Palace, temples and floating markets.
- Phuket & Krabi: beaches, islands and limestone cliffs.
- Chiang Mai: hilltop temples, night bazaars and jungle trekking.
- Koh Samui & Koh Phangan: palm-fringed island escapes.
- Ayutthaya: atmospheric ruins of an ancient capital.
Top tips for finding cheap flights to Thailand
- Book a few months ahead for the November–March high season.
- Avoid the Christmas and New Year peak for lower fares.
- Compare direct flights against one-stop routes via the Gulf or Asia.
- Be flexible with your dates — midweek departures are often cheaper.
Travel essentials
- Visa: UK travellers can enter Thailand visa-free for tourism for a set period; check the current allowance and any digital arrival card requirement before you fly.
- Currency: the Thai baht (THB).
Baggage & hand-luggage allowance for flights to Thailand
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 |
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.
