Well done, Thai AirAsia X. They are filing for bankruptcy but can refund their customers. I have been waiting for 26 months for a refund from a so called, 'national-flag' airline, namely KLM, with NO success. They don't answer emails, even to the CEO. It would appear that they have NO customer service dept. and are an absolute disgrace. They should have their passenger operating licence withdrawn.
KLM = the worst airline in the world.
