Airports of Thailand (AOT) anticipates a 3-6% increase in passenger numbers in 2026, potentially reaching between 130 and 135 million travelers, building on a record 126 million passengers across its six airports in 2025. Paweena Jariyathitipong, AOT President, noted that the first quarter of the current fiscal year (October–December 2025) already saw a 4% rise in passengers compared to the same period last year.
This growth is largely driven by AOT’s targeted strategies, including a focus on premium travelers and an expansion of charter flight operations, particularly from China and Japan. In the opening three months of fiscal 2026, Thailand received 1,200 charter flights, up from 900–1,000 flights in 2025.
However, AOT cautioned that full-year revenue projections remain uncertain due to several factors, most notably the planned increase in the Passenger Service Charge (PSC). Currently, international passengers pay 730 baht, but this fee is set to rise to 1,120 baht to better reflect operational costs, potentially adding around 10 billion baht to AOT’s annual revenue.
“Revenue this year is quite uncertain because PSC revenue is not being collected for the full year. Although it has been approved, the official implementation has not yet been announced,” Paweena explained. She added that the PSC’s full impact on revenue is expected next year, creating a revised revenue structure that offsets the decline in Aero income. AOT is also considering applying the PSC to transit passengers, a practice common in over 90% of global airports, to further cover costs and enhance service.
Looking ahead, AOT plans to submit an investment proposal to the Cabinet to expand passenger capacity. This includes the East Expansion project at Suvarnabhumi Airport, valued at 12 billion baht, which will raise annual capacity from 65 million to 70 million passengers. Originally approved in 2016 but delayed due to investment adjustments, the project is expected to begin bidding within the next one to two months, with construction scheduled for four years.
Additionally, AOT is seeking Cabinet approval for a 200-billion-baht South Terminal development. The project will add new terminals, runways, and a Maintenance, Repair, and Overhaul (MRO) facility, increasing Suvarnabhumi’s capacity to 120 million passengers annually. The organization is also progressing with the development of new airports, including the 80-billion-baht Andaman Airport in Phang Nga and the 70-billion-baht Lanna Airport in Chiang Mai.
Both projects have completed preliminary studies and are being prepared for initial Cabinet approval, after which AOT will resume detailed planning and begin land acquisition for construction.
