Airports of Thailand Increase Passenger Departure Tax To THB 1,120 From June 20, 2026

Why It Matters

The higher fee provides AOT with a substantial funding stream to modernize Thailand’s major airports, enhancing capacity and service quality at a time when tourism recovery is critical.

Key Takeaways

• International PSC rises to THB 1,120 effective June 2026
• AOT expects additional THB 10 billion annual revenue
• Domestic departure charge stays at THB 130 per passenger
• Funds earmarked for airport upgrades, including Suvarnabhumi SAT‑1
• AOT may extend PSC to transit passengers later

Pulse Analysis

Thailand’s airport departure surcharge has not been adjusted for two decades, making the June 2026 increase a landmark policy shift. The move reflects AOT’s assessment that the existing THB 730 fee no longer covers the true cost of operating six international hubs, from Suvarnabhumi to Hat Yai. By embedding the charge in ticket prices rather than cash collection, the airline industry can absorb the change with minimal disruption, while the government sidesteps direct tax debates. This strategic pricing aligns with global trends where airports fund capital projects through passenger‑linked fees rather than general taxation.

Financially, the extra THB 390 per passenger translates into an estimated THB 10 billion boost to AOT’s annual budget. Compared with departure taxes in Europe—where fees often exceed US$50—the Thai surcharge remains modest, positioning the country as a relatively low‑cost gateway. AOT argues that the modest increase will not deter travelers, especially as airlines can spread the cost across fare structures. Moreover, the predictable revenue stream enables long‑term planning for infrastructure, reducing reliance on volatile tourism receipts during economic downturns.

The revenue earmarked for upgrades promises tangible benefits: the Satellite Terminal 1 project at Suvarnabhumi, terminal expansions at Don Mueang, and enhanced immigration processing across all six airports. AOT also signals intent to levy the PSC on transit passengers, a practice common at over 90 % of global hubs, which could further diversify income. For investors and industry observers, the policy underscores a shift toward self‑financing airport models, where user fees directly fund capacity enhancements, thereby supporting Thailand’s broader goal of regaining its pre‑pandemic tourism momentum.
