AirAsia screwed me by cancelling my HKG-BKI flight while I was in the air incoming on QR ARN-DOH-HKG. I ended up buying a $1300 business class Malaysia flight via KUL as replacement, and will just contact American Express to charge back the Air Asia flight rather than suffering through whatever refund process Air Asia does. Happy to pursue legal action against AirAsia if it will help but I assume there is no economically viable way to do this. (I'm a US citizen, the flight is HK to Malaysia, they're a Malaysian airline, so unless there's US jurisdiction I assume this is essentially impossible.)
