My flight from Kathmandu to Dubai was delayed for 6 hours (first 4 hours, then 2 hours, ...) on March 12th due to the "bad weather condition". The weather was perfectly fine, and as you stated, all the other companies had apparently no problem whatsoever landing or taking off from the same airport... A word you wrote really echoed as far as my own customer experience with Fly Dubai is concerned: "compassion". It is indeed something that is cruelly missing from part of the staff of this company (their Phone Call Center ranging as my worst nightmarish customer service ever).
