Getting to Thailand — Flights, Routes & Arrival
Thailand is one of the world's most accessible long-haul destinations, with excellent air links to virtually every continent. Bangkok's Suvarnabhumi Airport is Southeast Asia's busiest hub, and getting to Thailand from the UK is straightforward, competitive, and — if you plan well — surprisingly affordable.
From the United Kingdom
Direct Flights
British Airways and Thai Airways operate direct flights from London Heathrow (LHR) to Bangkok Suvarnabhumi (BKK). Flight time: approximately 11 hours 30 minutes outbound, 12 hours return.
- British Airways: Daily service, Boeing 777-300ER. Expect to pay £450–700 return in economy, £1,800–3,000 in business class.
- Thai Airways: Daily service, Boeing 787 Dreamliner or Airbus A350. Comparable pricing, with superior business-class soft product.
One-Stop Connections
The widest choice (and often the cheapest fares) comes from one-stop connections via Middle Eastern hubs:
- Emirates via Dubai (DXB): Extensive schedule, excellent product. 2–4 hour layover typical.
- Qatar Airways via Doha (DOH): Award-winning airline, Hamad Airport is superb. Often the cheapest premium-economy option.
- Etihad via Abu Dhabi (AUH): Competitive fares, good business class.
- Turkish Airlines via Istanbul (IST): Wide network connecting UK regional airports (Manchester, Edinburgh, Birmingham) to Bangkok.
- Singapore Airlines via Singapore (SIN): Premium product, convenient for onward travel to southern Thailand.
Budget Option: Scoot (Singapore Airlines' low-cost arm) operates London–Singapore, connecting to Bangkok for as little as £350 return in economy — no frills, but a genuine bargain.
Booking Tips
- Best prices: Book 6–10 weeks ahead for the cheapest fares. Use Skyscanner or Google Flights with flexible dates.
- Peak season premium: December–January and July–August flights cost 30–60% more. Shoulder months (May, June, September, October) offer the best deals.
- Bangkok flights vs. Phuket/Chiang Mai: Flying into Bangkok and taking a domestic connection is almost always cheaper than booking a through-ticket to Phuket or Chiang Mai, unless you can find a direct international flight.
Bangkok Airports
Suvarnabhumi Airport (BKK)
Bangkok's primary international airport, 30km east of the city centre. All major international airlines and most full-service domestic carriers use Suvarnabhumi. Terminal facilities are extensive: currency exchange, SIM card vendors (airside and landside), free Wi-Fi, food courts, and the spectacular 3km underground rail link to the city centre.
Transfer to City:
- Airport Rail Link (ARL): ฿45, 30 minutes to BTS Phaya Thai. Fast, clean, runs 6:00–midnight.
- Taxi: ฿200–400 to central Bangkok (40–90 minutes depending on traffic). Use the official taxi queue at Level 1 — always insist on the meter. Add ฿50 airport surcharge and all tolls (฿25–75).
- Grab: ฿250–500 depending on time and distance. Pickup at designated areas.
- Limo/Private Transfer: ฿1,000–2,500 pre-booked. Convenient, door-to-door.
Don Mueang Airport (DMK)
Bangkok's older airport, 24km north of the city. Used exclusively by budget carriers: AirAsia, Nok Air, Thai Lion Air, and some Thai VietJet services. If connecting between international (BKK) and domestic budget (DMK), free shuttle buses run between the airports (40–90 minutes depending on traffic) — allow at least 3 hours for the transfer.
Regional Airports
Thailand has an excellent domestic flight network. Key airports beyond Bangkok:
| Airport | Code | Serves | Flights from Bangkok |
|---|---|---|---|
| Phuket | HKT | Andaman coast | 1h20m, from ฿1,200 |
| Chiang Mai | CNX | Northern Thailand | 1h15m, from ฿1,000 |
| Koh Samui | USM | Gulf islands | 1h, from ฿3,000* |
| Krabi | KBV | Ao Nang, Railay, Ko Lanta | 1h20m, from ฿1,200 |
| Hat Yai | HDY | Deep south | 1h30m, from ฿1,000 |
| Chiang Rai | CEI | Golden Triangle | 1h30m, from ฿1,200 |

*Koh Samui airport is privately owned by Bangkok Airways, which holds a near-monopoly on flights. Prices are significantly higher than other domestic routes. Budget alternative: fly to Surat Thani and take a bus/ferry combo.
Overland Crossings
Thailand shares land borders with four countries, with numerous official crossing points:
- Malaysia → Thailand: The most-used crossing is by train or bus via Padang Besar (Perlis–Songkhla). The Eastern & Oriental Express luxury train runs this route. Also crossings at Betong, Sungai Kolok, and by ferry from Langkawi to Satun.
- Cambodia → Thailand: The Aranyaprathet/Poipet crossing (to/from Siem Reap) is the busiest. Also Cham Yeam/Hat Lek (to/from Koh Kong).
- Laos → Thailand: The Friendship Bridge (Nong Khai to Vientiane) is the main crossing. Also crossings at Chiang Khong/Huay Xai (popular for Mekong slow-boat connections) and Nakhon Phanom/Tha Khek.
- Myanmar → Thailand: Mae Sot/Myawaddy is the most accessible crossing, though border situations can change. Mae Sai/Tachileik (Golden Triangle) allows day visits.
Arrival Procedures
Immigration
| Nationality | Visa Required | Stay Allowed | Extension |
|---|---|---|---|
| UK citizens | No (visa exemption) | 60 days | 30 days (at immigration) |
| EU citizens | No (most countries) | 60 days | 30 days |
| US citizens | No | 60 days | 30 days |
| Australian | No | 60 days | 30 days |
A return or onward ticket may be required (though rarely checked at airports — more often at land borders). Passport must be valid for at least 6 months from arrival.
Customs
Duty-free allowances: 200 cigarettes or 250g tobacco; 1 litre of alcohol. Penalties for drug importation are severe — including the death penalty for trafficking. This is not an abstract threat.
SIM Cards
Available at all international airports, both airside (after immigration) and landside. The three major operators — AIS, DTAC, and TrueMove H — offer tourist SIMs at counters in the arrivals hall. A 30-day unlimited data SIM costs ฿300–600 (£7–14). Coverage across Thailand is excellent for all three.
