Thai AirAsia will run up to 135 domestic flights a day in Oct-Dec 2026, up more than 50% from the Q3 peak of 88, and says domestic travel should pick up into early next year. It cut flights about 30% in Q2 because of higher fuel costs and slow mid-year travel. For a business that depends on domestic travellers, such as tour operators, hotels in Chiang Mai, Phuket, Krabi or Udon Thani, and transport, this points to more seat capacity into the high season. Plan staffing and stock around it, and check whether your routes are among those added.
