Why do they make it so hard to give them extra money! --So when you book wrong dates and call/mail them to change ticket, there is no fee? I know the CGK office won't take cards over the phone, but if I call TG in Thailand, and try to book CGK-BKK, will they do they allow that over the phone? I know MH will with there KUL call center, but ONLY if the call center in CGK is closed....
