2026 Thailand Airport Fees (AOT): What Travelers Need to Know

Thailand's major airports are getting a facelift — and travelers are helping foot the bill. Starting June 20, 2026, Airports of Thailand (AOT) is raising the international departure Passenger Service Charge (PSC) at its six busiest hubs.

This guide answers the top questions travelers are searching for — Thailand airport fee increase 2026 and Airports of Thailand AOT fee — with clear, quotable facts based on official AOT announcements and Civil Aviation Board approvals as of May 2026. For the news context behind the change, see our reporting on Thailand airports raising international departure fees 53%.

What is the Thailand airport fee increase in 2026?

The Passenger Service Charge for international outbound passengers at AOT airports jumps 53% — from 730 THB to 1,120 THB per person — effective June 20, 2026.

This is not a new tax but an adjustment to the existing airport development fee. The extra revenue (around 10 billion THB annually) will fund infrastructure upgrades, including the new South Terminal at Suvarnabhumi and capacity expansions across the network.

Which airports are affected by the AOT fee increase?

Only the six airports managed by Airports of Thailand (AOT) are raising the international PSC to 1,120 THB:

• Suvarnabhumi (BKK) — Bangkok
• Don Mueang (DMK) — Bangkok
• Phuket (HKT)
• Chiang Mai (CNX)
• Mae Fah Luang–Chiang Rai (CEI)
• Hat Yai (HDY)

Smaller airports not operated by AOT (e.g. Krabi, Surat Thani, or U-Tapao) are not affected by this specific increase.

Is the new AOT airport fee included in my ticket price?

Yes — the 1,120 THB fee is automatically added to your airfare when the ticket is booked or issued on or after June 20, 2026. You won't pay anything extra at the airport.

No need to queue at a separate counter or worry about cash at departure. Airlines and booking platforms collect it upfront, and it's listed on your e-ticket.

How much is the new Thailand airport fee in USD (and other currencies)?

1,120 THB is roughly USD 34, EUR 31, or GBP 26 at exchange rates as of May 2026. The previous fee of 730 THB was about USD 22, so the real increase per passenger is around USD 12.

What about domestic flights and other fees?

Domestic Passenger Service Charges stay unchanged at 130 THB per person to support local tourism. There are also no changes to arrival fees, visa-related charges, or any other AOT passenger fees. The hike applies only to international departures.

Quick comparison: old vs new AOT Passenger Service Charges (2026)

• International departure — previously 730 THB (until 19 June 2026), now 1,120 THB (from 20 June 2026) — an increase of +390 THB (+53%).
• Domestic departure — unchanged at 130 THB in both periods.

Will this affect my travel plans?

For most travelers, the impact is small — just about USD 12 more per person — but it's worth factoring into your budget if you're flying out of Phuket, Bangkok, or Chiang Mai after mid-June.

If you're booking a multi-city trip or have an open-jaw ticket, double-check the departure airport and date. Tickets issued before June 20 but with departures after may still use the old rate — always confirm with your airline.

Pro tips for avoiding airport fee surprises in Thailand

• Book early if you want to lock in pre-increase fares — tickets issued before June 20 may keep the old rate.
• Use low-cost carriers or promotions — the fee is the same across airlines, but base fares vary widely.
• Check your e-ticket breakdown for line items labeled "PSC", "Airport Fee", or "Passenger Service Charge".
• Frequent flyers: the fee applies per departure, so round-trip tickets include it on the outbound leg only.
• Watch AOT's official channels — fees can be reviewed again in future years on airportthai.co.th.
• No exemptions for children, infants, or transit passengers (unless your airline offers specific waivers).
• Save time at the gate: if you're flying out of Don Mueang, take advantage of the fast-track departure lanes for e-passport holders to cut wait times.

Thailand's airports are investing heavily in better facilities, faster processing, and expanded terminals — this modest fee hike is how they're funding it without raising ticket prices dramatically elsewhere. The change is straightforward, transparent, and fully baked into your booking.

For the absolute latest confirmation, visit the official AOT website or contact your airline directly. You can also check schedules and procedures via Suvarnabhumi Airport and Don Mueang International Airport.

Safe travels — whether you're heading to the beaches of Phuket or the mountains of Chiang Mai, Thailand is still one of the world's best-value destinations.
