Say goodbye to sub-B1,000 international flights as airport taxes rise for overseas travel on June 20

Anyone living for a dirt-cheap airfare deal might want to brace themselves. Airports of Thailand (AOT) has officially confirmed a hefty rise in the international passenger service charge, better known as airport tax, which means flying abroad from Thailand soon costs noticeably more.

Right now, travellers pay B730 per person for international departures. From June 20 2026, that jumps to B1,120 – an extra B390, or roughly a 53 percent increase. The charge already comes folded into ticket prices at checkout, so nobody escapes it at the payment screen. Domestic flights stay put at B130 per passenger, which at least spares local weekend getaways.

The revised fee applies across AOT's six major airports handling international routes:

• Suvarnabhumi Airport (BKK)
• Don Mueang International Airport (DMK)
• Chiang Mai International Airport (CNX)
• Mae Fah Luang Chiang Rai International Airport (CEI)
• Phuket International Airport (HKT)
• Hatyai International Airport (HDY)

So whether it's a quick Tokyo city break, a Seoul shopping weekend or a long-haul summer holiday, the added cost quietly tags along.

Even with the increase, Thailand still ranks among Southeast Asia's more affordable travel hubs. But for anyone already plotting post-2026 holidays, this is a good nudge to watch airfare prices before they creep up. Booking early, cashing in airline miles or locking in a promotional fare sooner rather than later suddenly sounds a lot more appealing.
