Booking budget domestic flights in Thailand

Book your flights 3 to 6 weeks in advance directly through airline websites like AirAsia, Nok Air, or Thai Lion Air to get the lowest fares. Use a price aggregator like Google Flights to track routes, but always complete the final purchase on the airline's official site to avoid third-party service fees.

1. Compare prices first. Use Google Flights or Skyscanner to see which airlines fly your route. Enter your dates to identify the cheapest days to fly, but do not click 'book' through them.
2. Visit the airline website. Go directly to the airline’s official site (airasia.com, nokair.com, lionairthai.com). Prices are usually identical or cheaper here, and you avoid booking platform commissions.
3. Watch the baggage limits. Budget fares often include 0kg of checked baggage. If you have a suitcase, add your checked luggage weight during the booking process online; it is significantly cheaper than paying at the airport check-in counter.
4. Confirm payment method. Have your passport number and a credit card handy. Many Thai budget airlines offer a 'promptpay' or bank transfer option for locals, but as a tourist, stick to the credit/debit card payment portal.

Which airport in Bangkok should I use?

Bangkok has two airports: Suvarnabhumi (BKK) and Don Mueang (DMK). Most budget airlines operate out of Don Mueang, while international carriers usually use BKK. Double-check your ticket so you don't go to the wrong one.

Can I fly with a carry-on only?

Yes, but keep it under 7kg. They are very strict and will weigh your bag at the gate. If you are over, you will be forced to pay a heavy checked-baggage fee at the gate.
