Thailand’s aviation authorities have raised the passenger service charge (PSC) — commonly known as “airport tax” — for outbound travelers at six regional airports, effective 1 October 2025. The increase affects both domestic and international flights.

At the airports in Krabi, Surat Thani, Ubon Ratchathani, Khon Kaen, Nakhon Si Thammarat and Phitsanulok, the fee for international departures has risen from 400 baht to 425 baht per person.

Domestic travelers will now pay 75 baht instead of the previous 50 baht.

The charge is built into the ticket price.

The extra 25-baht fee is part of a broader plan linked to the rollout of advanced passenger-processing technology — including automated check-in, self-service kiosks and automated baggage drop systems — which the government says will modernize airport services and improve efficiency.

Meanwhile, the national airport operator Airports of Thailand (AOT) is studying a more substantial PSC increase for its six major airports, including the international gateway Suvarnabhumi Airport.

Under the proposal, PSC for international departures could rise from 730 baht to as much as 1,120 baht per person.

If approved, the higher rate may take effect in early 2026.

Transport officials say that the revenue generated from these fee hikes will be used to upgrade airport infrastructure, improve passenger services, and support ambitions to position Thailand as a regional aviation hub.

The modest increase at regional airports from October 2025 goes into effect immediately.

The larger PSC revision under AOT remains under review, pending formal approval and a future announcement.
