Thai Airways to cut May flight frequencies across domestic and international routes

Thai Airways International (THAI) will reduce flight frequencies across its network in May 2026, covering domestic services as well as routes in ASEAN, North Asia, South Asia, and Europe, citing rising fuel costs and weaker passenger demand during the off-peak travel season.

The adjustments reportedly reflect continued pressure from high operating costs alongside a seasonal slowdown in travel demand. Domestically, flights on several routes will be reduced, including Bangkok–Khon Kaen, Bangkok–Udon Thani, and Bangkok–Ubon Ratchathani.

In ASEAN, services such as Bangkok–Phnom Penh and Bangkok–Singapore will also be cut. In North Asia, reductions include key routes to Tokyo, Beijing, Shanghai, Seoul, Taipei, and Hong Kong, while the Bangkok–Kaohsiung route will be suspended during the period.

In South Asia, Bangkok–Hyderabad, Bangkok–Delhi, and Bangkok–Mumbai services will be scaled back. European routes, including Istanbul, Frankfurt, Munich, Copenhagen, Oslo, and Stockholm, will also see reduced frequencies throughout May.
