OAG's August data shows Thailand's total seat capacity down 1.7% year-on-year to 7.19 million, with Vietnam ranked No.2 for a second month. Don Mueang capacity fell 7.5%, driven by Thai AirAsia cutting 23.4%, after it cut 30% of capacity in May and June due to fuel prices linked to Middle East conflicts. Low-cost seats in the region fell 4.9%. For a business serving tourists, expect fewer budget-flight options into Bangkok's Don Mueang and fewer routes to other provinces, so check your inbound booking assumptions and consider direct-flight destinations such as Da Nang and Phu Quoc as competition.
