The Japan Civil Aviation Bureau (JCAB) recently announced that it would not permit Thai-based airlines to operate charter flights, add any new flights, apply for further flight frequencies, or allow the change of any aircraft types as of March 29. This prompted AirAsia X to work closely with JCAB and the Thai government to resolve the situation as soon as possible to ensure flights continue.
For the month of May, JCAB has given AirAsia X permission to operate rescue flights between Bangkok and Sapporo. This will allow the airline to accommodate any AirAsia X passengers who have been affected by the change. The airline will use the same Airbus A330-300 aircraft with a code D7. Passengers who have already booked flights between Bangkok and Sapporo from June 1 will have to switch their flight date to sometime in May, change their travel destination, cancel their flight for credit, or receive a refund.
