Issuing boarding pass takes too long. Either not enough people to help or the process is just way too slow or long. I tried many times to contact a representative on the phone, no one is available to take your call. Our last flight was cancelled and we were given another flight the next day and Starlux would not guarantee a free hotel accommodation to help my family.
