Well you would be wrong.. Nok is a very nice little low cost carrier. I have been flying with them for 10 years plus. Not any perks other than customer service that works, friendly ground staff and flight crews, and easy check in each and every time.
AA is a pain in the ass and I dont fly them for a simple reason. I get tired of having to tick away better seat extra luggage, and insurance. But they are the big player here in Asia. You will get some refund, but when and how much nobody knows. Most airlines take months to refund flights. This will be the same.
Good luck though, I would take it easy for a while and let this mess die down a bit. I hope!!
