AOT Reports 126 Million Passengers in FY2025: Thailand’s Tourism Recovery Hits Full Stride
Airports of Thailand (AOT) just released fiscal year 2025 numbers that tell a story of genuine recovery. The state airport operator served 126 million passengers across its six major airports during fiscal year 2025 (October 2024 through September 2025), marking an 11% increase year-on-year. While Q4 specifically saw a slight dip with 28.75 million passengers (down 1% year-on-year), the full-year growth and ambitious expansion plans signal that Thailand’s aviation sector is experiencing sustained momentum despite regional headwinds.
FY2025 Performance
AOT’s fiscal year 2025 performance demonstrates resilience even as quarterly numbers fluctuate. The 126 million total passengers represent steady progress toward pre-pandemic levels, though the Q4 softness (July-September 2025) reveals challenges that couldn’t be ignored. International passengers in Q4 dropped 5% year-on-year while domestic passengers rose 5%, suggesting that while Thai nationals continue traveling, foreign tourist numbers faced pressure during the summer months.
Revenue told a more positive story. Total aeronautical revenue for FY2025 reached 68.59 billion baht, up 1.12% from the previous year. The modest revenue growth despite an 11% passenger increase reflects ongoing price competition and shifts in passenger mix toward budget travelers who generate lower per-passenger revenue.
The Q4 core profit of 4.02 billion baht declined 8% year-on-year but beat analyst consensus by 13%, demonstrating that AOT managed costs effectively even as passenger numbers softened. The organization attributes Q4’s international passenger decline primarily to lower Chinese tourist numbers—a trend affecting all Southeast Asian destinations but hitting Thailand particularly hard given its historical dependence on that market.

What the Numbers Really Mean
The divergence between strong full-year performance and soft Q4 results reveals Thailand’s tourism sector navigating complex crosscurrents. The 11% annual growth proves Thailand remains competitive and attractive to international travelers. The Q4 decline shows that competition from Vietnam and Malaysia, combined with safety perceptions following incidents like the Wang Xing kidnapping in January 2025, created genuine headwinds during peak summer travel season.
Paweena Jariyathitipong, AOT’s acting president, emphasized that the full-year growth demonstrates the resilience of Thailand’s aviation sector despite challenges. The organization projects FY2026 (October 2025 through September 2026) will see passenger volumes exceed 135 million—a 7% increase that would bring Thailand closer to 2019’s 142 million passengers.
Flight operations data provides additional context. AOT handled 602,195 total flights in the first nine months of FY2025, a 9.79% increase. The addition of seven new airlines for the winter 2025-2026 schedule (including United Airlines, Air France, and Etihad Airways) plus 11 new routes suggests airlines remain confident in Thailand’s market potential despite Q4’s softness.
The confidence becomes clearer when examining long-term projections. AOT expects passenger volumes will reach 240 million annually by 2032—nearly double current levels. This forecast isn’t wishful thinking but rather informed by demographic trends, rising Asian middle-class travel, and Thailand’s strategic positioning as a regional hub.
Infrastructure Investment: The $10 Billion Bet
AOT isn’t just managing current capacity; it’s betting approximately $10 billion over the next five years that Thailand’s aviation growth will accelerate. This represents serious commitment beyond typical maintenance and minor upgrades. The organization is fundamentally transforming Thailand’s airport capacity based on projections that justify massive capital expenditure.
Suvarnabhumi Airport, Thailand’s busiest facility handling the bulk of international traffic, will see accelerated construction of its East Expansion project targeting completion by 2030. The development will increase capacity from 65 million passengers annually to 80 million. AOT recently paid 193.08 million baht to King Power to acquire land needed for the expansion, demonstrating concrete progress rather than mere planning.
Don Mueang International Airport, primarily serving low-cost carriers and domestic routes, plans construction of a new international terminal to increase capacity from 30 million to 50 million passengers annually. This expansion recognizes Don Mueang’s crucial role in Thailand’s aviation ecosystem, particularly for budget-conscious travelers who drive volume.
Phuket International Airport will expand to handle 18 million passengers yearly, up from 12.5 million. Given Phuket’s status as Thailand’s premier beach destination, this capacity increase acknowledges that island tourism will continue growing even as mainland destinations face stronger competition.
Chiang Mai International Airport targets increasing capacity from 8 million to 15 million passengers annually—a near-doubling that reflects northern Thailand’s rising appeal to both domestic and international travelers. Mae Fah Luang-Chiang Rai International Airport plans to double passenger handling capacity from three million to six million annually, with expansion work expected to finish by 2033.
These investments create capacity for growth that doesn’t yet exist. If projections prove overly optimistic, Thailand will have spent billions on underutilized infrastructure. If projections prove conservative, these expansions position Thailand to capture aviation market share as regional demand continues growing.

The Revenue Diversification Play
Beyond infrastructure, AOT is pursuing revenue diversification that could reshape how Thai airports generate income and reduce dependence on volatile passenger service charges. The organization held an AOT Property Showcase in April 2025, attracting significant interest from domestic and international investors. Twenty-eight project proposals were submitted, covering hotels, maintenance and repair facilities, private jet terminals, logistics hubs, training centers, EV repair facilities, car showrooms, EV charging stations, and terminal attraction projects.
This diversification matters because aeronautical revenue faces limitations based on passenger volume and regulated fees. The recent approval to increase Passenger Service Charges from 730 baht to 1,120 baht for international outbound passengers will generate an estimated 10 billion baht in additional annual revenue starting in 2026. AOT expects approximately 35 million international outbound passengers yearly, making this 390-baht increase per passenger a significant revenue boost specifically earmarked for infrastructure development.
However, the PSC increase creates its own complications. Thailand already competes with destinations offering lower costs to airlines and passengers. Raising fees while Malaysia extends visa-free entry through 2036 and Vietnam aggressively courts Chinese tourists creates pricing disadvantages. AOT must balance revenue needs against competitive positioning—a calculation that becomes more difficult as regional competition intensifies.
The King Power situation adds another layer of complexity. Trade accounts receivable relating to deferred concession payments from King Power stood at approximately 14 billion baht at end-FY25, up from 10 billion baht in June 2025. AOT is negotiating new duty-free concession contracts with King Power, with results expected to be proposed to AOT’s board in late November 2025. The outcome will significantly impact future non-aeronautical revenue, as duty-free operations historically generated high-margin income.
The Competitive Context: What Q4 Numbers Reveal
The Q4 passenger decline, particularly the 5% drop in international passengers, doesn’t happen in isolation. Vietnam welcomed 3.5 million Chinese tourists through August 2025, a 44% year-on-year increase. Malaysia surpassed Thailand to become Southeast Asia’s most-visited country in Q1 2025. Singapore’s Chinese arrivals reached 85% of 2019 levels with strong growth trends.
Thailand maintained the highest absolute number of Chinese visitors in Southeast Asia with 6.73 million in 2024, but the Q4 international passenger decline suggests this dominance is eroding. The 24% year-on-year drop in Chinese arrivals to Thailand in Q1 2025 created momentum that continued affecting Q4 numbers.
Safety perceptions play an undeniable role. The Wang Xing kidnapping in January 2025 raised security questions among Chinese travelers. Persistent issues with scam centers targeting Chinese nationals created ongoing reputational damage. “Chinese travelers who have never been to Thailand are still scared,” acknowledged Thienprasit Chaiyapatranun, president of the Thai Hotels Association.
Flight capacity constraints compound perception issues. Capacity between mainland China and Thailand remains 35% lower than 2019 levels, creating a structural bottleneck even when demand exists. Airlines make capacity decisions based on projected demand and profitability—the continued capacity gap suggests carriers don’t yet see conditions supporting restoration to pre-pandemic levels.

The India Factor: Strategic Diversification
While Chinese tourist numbers create headlines, India’s outbound travel surge provides Thailand with strategic diversification that could prove more valuable long-term. Outbound international flight capacity from India has exploded to 110% of 2019 levels, while China’s capacity remains stuck at 77%.
For Thailand, rising Indian tourism provides a hedge against Chinese market volatility. If China can deploy travel advisories against Japan over political disputes, it could theoretically target Thailand, Vietnam, or Malaysia next. Building strong Indian tourist flows reduces vulnerability to any single market’s political decisions.
Indian travelers also bring different spending patterns. They allocate more budget to shopping compared to Chinese tourists, who spend 9.5% on experiences and nightlife. Thailand’s established shopping infrastructure—from street markets to luxury malls—positions it well to capture Indian tourism spending.
The Q4 numbers showed domestic passenger growth of 5% offsetting some international decline. While this primarily reflects Thai nationals traveling, it also suggests Thailand’s domestic tourism market provides baseline demand that stabilizes airport operations even when international numbers fluctuate.
What This Means for Expats and Investors
For expats living in Thailand and investors considering the market, AOT’s numbers provide mixed signals requiring nuanced interpretation. The full-year 11% passenger growth demonstrates Thailand remains attractive and competitive. The Q4 softness shows that Vietnam and Malaysia are capturing market share, particularly from Chinese tourists who historically drove Thailand’s tourism economy.
The massive infrastructure investments signal government and corporate confidence in Thailand’s long-term aviation future. The $10 billion being deployed across airport expansions creates construction opportunities, jobs, and eventual capacity for growth. However, these investments also create financial obligations that must be serviced regardless of whether passenger projections materialize.
The PSC increase starting in 2026 will affect expat travel budgets. An additional 390 baht per international departure adds up for frequent travelers—those making six international trips annually will pay an extra 2,340 baht ($67) in fees. For retirees on fixed incomes or digital nomads traveling regularly, this incrementally increases Thailand’s cost of living.
The revenue diversification through property development around airports could create business opportunities for expats with relevant expertise in hospitality, logistics, EV infrastructure, or aviation services. The 28 project proposals submitted to AOT’s showcase in April 2025 suggest active interest from investors seeking to participate in Thailand’s aviation ecosystem expansion.
The Road to 240 Million: Realistic or Wishful?
AOT’s projection of 240 million annual passengers by 2032 requires sustaining approximately 9-10% annual growth from current levels—achievable but not guaranteed. Several factors will determine whether Thailand reaches this target or falls short.
Regional competition is intensifying, not easing. Vietnam’s 44% growth in Chinese tourists, Malaysia’s visa-free extension through 2036, and Singapore’s continued appeal to high-spending travelers all create headwinds. Thailand must not only grow but grow faster than competitors to maintain regional market share.
The Chinese tourist market’s evolution presents both risk and opportunity. While overall Chinese outbound travel is expanding, travelers are increasingly sophisticated, independent, and seeking authentic experiences rather than traditional package tours. Thailand must adapt its offerings to appeal to these evolved preferences while competing with Vietnam’s “fresh and authentic” appeal.
Indian tourism growth provides genuine upside that could exceed projections. If India’s economy continues growing at 6-7% annually and outbound travel spending reaches projected levels, Thailand is well-positioned to capture substantial Indian tourist flows. The combination of cultural affinity, established tourism infrastructure, and geographic proximity creates natural advantages.
Infrastructure improvements at competitors’ airports will affect Thailand’s relative positioning. Singapore continues upgrading Changi Airport, Vietnam is expanding Da Nang and other facilities, and Malaysia is investing in KLIA and regional airports. AOT’s $10 billion investment must be executed efficiently to maintain competitive service standards while managing costs.
The Bottom Line
AOT’s FY2025 performance tells a story of recovery with complications. The 126 million passengers and 11% annual growth demonstrate Thailand’s aviation sector is rebounding and expanding. The Q4 softness with 5% international passenger decline reveals that competition has intensified and Thailand cannot assume its historical dominance will automatically continue.
The massive infrastructure investments signal confidence but also create expectations that must be met. If passenger growth accelerates as projected, Thailand will have positioned itself perfectly for long-term success as a regional aviation hub. If growth stalls or competitors capture larger market shares, Thailand will face years of servicing debt on underutilized infrastructure.
For expats and travelers, these dynamics manifest as improved facilities, more flight options, and higher fees starting in 2026. The balance between infrastructure quality and cost competitiveness will determine whether Thailand maintains its appeal or gradually loses ground to neighbors offering similar experiences at lower prices with fewer hassles.
The next few years will be telling. AOT’s FY2026 projection of 135 million passengers represents 7% growth—solid but not spectacular. If Thailand can sustain this growth while completing infrastructure upgrades and diversifying tourist source markets, the 240 million passenger target for 2032 becomes achievable. If competition continues eroding market share and structural issues persist, Thailand may find itself managing overcapacity rather than celebrating growth.
The numbers are in. Thailand’s aviation sector is growing. The question is whether it’s growing fast enough to justify the billions being invested and sustain the country’s position as Southeast Asia’s premier aviation hub.
