Starting May 2026, flying out of Thailand will become more expensive, as departure fees at six of the country’s busiest international airports are set to rise by more than 50%. Airports of Thailand, the state-run operator, announced that the passenger service charge (PSC) for outbound international flights will increase from 730 baht (around US$23) to 1,120 baht (approximately US$35).
The new fee will apply to departures from Bangkok’s Suvarnabhumi and Don Mueang airports, as well as Phuket, Hat Yai, Chiang Mai, and Chiang Rai, while domestic flight charges will remain the same.
The 53% increase has already received preliminary approval from Thailand’s aviation authorities and is awaiting final confirmation from the transport minister. Authorities say the higher fee is unlikely to discourage travelers, as airfares and overall travel costs have a much bigger impact on demand than airport charges. Unlike many countries, Thailand does not charge similar fees for incoming or transit passengers.
Revenue from the increased PSC is expected to reach around 10 billion baht per year. This money will be used to improve airport security, upgrade facilities such as restrooms and air-conditioning, and ensure stable power supply. Some of the funds will also go toward future airport projects and help reduce debt-related expenses.
