- Thai Lion Air launched operations between Bangkok Don Mueang (DMK) and Osaka Kansai (KIX) on 28 March. The carrier will operate the 4,152-kilometre sector five times weekly. Originally scheduled to be flown using 737 MAX 9s, the airline is currently serving the airport pair using its A330-300s due to the temporary grounding of the Boeing aircraft type. Thai Lion Air becomes the fourth carrier to serve this airport pair, with Thai AirAsia X serving the sector twice-daily, while NokScoot offers six weekly flights and Scoot three. With Thai Lion Air joining the airport pair, it means that there are 28 weekly flights between the two points. Indirect competition is also provided on the city pair, with Thai Airways (twice-daily) and Japan Airlines (daily) operating between the Japanese airport and Bangkok Suvarnabhumi, with both airlines using wide-body aircraft on the route, with Thai Airways even operating one of its daily flights using A380s according to OAG schedules.
