I purchased an Orbitz.com flight package which included a Honolulu to Kona flight aboard Mesa subsidiary GO! airlines. the GO! flight was cancelled because the pilots had "timed out", forcing me to purchase a full fare Hawaiian Airlines ticket to Kona. Despite numerous E-mails and phone calls to Orbitz, Mesa and GO! "customer service", I have yet to be reimbursed for the Hawaiian Airlines ticket. Several months ago a GO! flight from Honolulu to Hilo overshot the Hilo airport as both pilots had dozed off and had to be awakened by Hilo control tower. I will never again deal with Orbitz, Mesa or GO!.
