Thailand to Increase International Flight Tax by 53% in 2026: What Travelers Must Know

Thailand has announced a major update for international travelers: the country will raise its Passenger Service Charge (PSC) for international departures by 53% starting in 2026. This change is expected to impact millions of passengers and could make flying out of Thailand more expensive in the coming year.

In this guide, we break down what the new fee means, which airports are affected, why the increase was approved, and how travelers can prepare.

What Is Changing in Thailand’s Airport Tax?

The Civil Aviation Authority of Thailand (CAAT) has officially approved a significant increase in the PSC—commonly known as the airport tax—for international flights.

Here’s the breakdown:

• Current PSC for international flights: 730 baht

• New PSC (from 2026): 1,120 baht

• Increase: +390 baht (approximately USD $11–12)

This 53% increase applies only to international flights.
Domestic PSC remains unchanged at 130 baht.

This means that anyone flying out of Thailand internationally in 2026 will automatically see a higher airport fee included in their ticket price.

When Will the New Airport Tax Be Implemented?

The new rate is expected to take effect in early 2026, likely within the first quarter (Q1).

Thailand’s aviation regulators must announce the implementation at least four months before the official start date, giving passengers and airlines time to adjust.

Travelers who book flights before the effective date may still pay the old PSC.

Which Airports Are Affected by the New PSC?

The increased airport tax will be applied at all major airports operated by Airports of Thailand (AOT). These include:

• Bangkok Suvarnabhumi Airport (BKK)

• Bangkok Don Mueang Airport (DMK)

• Chiang Mai Airport (CNX)

• Chiang Rai Airport (CEI)

• Phuket International Airport (HKT)

• Hat Yai Airport (HDY)

These airports serve the majority of Thailand’s international traffic, meaning most travelers will be affected by the hike.

Why Is Thailand Increasing the International Flight Tax?

According to AOT, the higher PSC will help fund major infrastructure improvements, such as:

Airport Upgrades

Thailand is focusing on modernizing existing terminals, increasing capacity, and reducing congestion.

New South Terminal at Suvarnabhumi Airport

One of the largest investments is the construction of a major new terminal that aims to transform Bangkok’s main airport into a more efficient travel hub.

Enhanced Safety and Security

Improved technology and upgraded security systems are also part of the expansion plan.

AOT expects the new PSC to generate around 10 billion baht per year, based on an estimated 35 million international passengers annually. 

How Will This Impact Travelers?

The airport tax increase will directly affect total ticket prices for international departures from Thailand. Here’s what travelers can expect:

1. Higher Airfare

The additional 390 baht fee will be added automatically to all international tickets.

2. More Impact on Budget Travelers

Those who rely on low-cost carriers or take frequent short trips will feel the increase more sharply.

3. Travel Agents and Airlines Must Update Systems

Booking platforms, travel agencies, and airline websites will adjust their pricing structures to include the new PSC.

4. Frequent Flyers Will Pay More Annually

While the amount may seem small, it adds up quickly for travelers who fly often.

How Travelers Can Plan Ahead

To avoid unexpected costs or to save on flight expenses, here are a few practical tips:

Book Before Early 2026

If your travel dates are flexible, booking before the new tax comes into effect can help you avoid the higher fee.

Compare Airlines

Some carriers may absorb small fee hikes during promotional periods. Always compare fares before booking.

Account for PSC in Your Travel Budget

When planning trips to Southeast Asia, factor in the airport tax as part of your total travel cost.

Watch for Airline Sales and Discounts

Promotions may help offset the increased PSC, especially for long-haul flights.
