Don t fly with them!!! We had a flight from krabi to Chiang mai on November 9th. Nok air didn’t had all the documents allowing them to fly. As a consequence our flight got delayed more than 4 hours! We missed our conection in Bangkok and they , instead of putting us on another flight to Chiang mai, sent is to Chiang Raí!!!!!
They are not serious, don t give information and ignores all complaints!!!
And the flight was not cheap!!
