The official SRT website for booking train travel

For train journeys—especially the highly popular sleeper trains heading North (Chiang Mai), and to a slightly lesser extent heading South—it is recommended to use the official website of the State Railway of Thailand: dticket.railway.co.th

✅ You will often find the lowest prices there, completely commission-free.
✅ The platform allows you to purchase electronic tickets with a QR code that can be used directly at the station.
✅ It is also a good idea to download the D-Ticket app to easily pull up your tickets and scan them at the platform gates, particularly at Bangkok’s Krung Thep Aphiwat Central Terminal.

⚠️ Important note: tickets for sleeper trains can be booked up to 180 days in advance and sell out very quickly, especially during peak travel season. The more comfortable lower berths are always the first to sell out, so make sure to secure yours well ahead of time!

Booking domestic flights in Thailand

For domestic flights, it is usually better to book directly on the airline websites. This allows you to easily manage luggage options and lock in the best available rates.

Here are the main airlines operating in Thailand:
✈️ Air Asia
✈️ Thai Lion Air
✈️ Bangkok Airways
✈️ Thai Airways
✈️ Nok Air
✈️ Vietjet Air

Tip: outside of special promotional windows, the earlier you book, the cheaper it gets—especially with Air Asia.

Important rules to know before booking

Here are a few essential points to keep in mind when handling your transport bookings in Thailand:

• Sleeper trains are in very high demand: book as early as possible, especially if you want a lower berth.
• Certain bus routes only open up for booking 30 to 60 days before departure. If you cannot find a ticket yet, simply check back later.
• ✈️ For domestic flights, plan ahead: the best rates are almost always secured by booking well in advance.
• For local transport (short distances or less touristy areas), online booking might not be an option. In those cases, you can arrange it through your hotel, a local agency, or by going straight to the local bus terminal.
