The Civil Aviation Board of Thailand has officially approved a 53 percent increase in passenger service charges for international flights, a request put forth by Airports of Thailand Plc (AOT). The decision, made during a meeting on December 3, 2025, led by Minister of Transportation Phiphat Ratchakitprakarn, will see the airport tax for international departures rise from 730 baht (approximately Rp382,000) to 1,120 baht (approximately Rp586,000). This adjustment means international travelers can expect an increase of around 309 baht (approximately Rp204,000) in their ticket prices, as these charges are typically included at the time of purchase.

Conversely, passenger service charges for domestic flights within Thailand will remain unchanged at 130 baht (Rp68,000). This ensures that internal travel to popular destinations like Phuket, Chiang Mai, or Krabi from Bangkok will not be directly impacted by the new international fee structure. AOT, which manages six key airports including Suvarnabhumi, Don Mueang, Phuket, Chiang Mai, Hat Yai, and Chiang Rai, will publish the new rates four months prior to their effective date.

AOT projects that the increased airport tax will generate an additional 10 billion baht (Rp5.2 billion) annually, based on an estimated 35 million international passengers using its airports each year. These substantial funds are earmarked for significant improvements to Thailand's airport infrastructure. The primary focus will be on expanding terminals and enhancing services to better accommodate the growing number of international travelers, particularly at Bangkok's Suvarnabhumi Airport, the nation's busiest aviation hub.
