I booked my Sept flight direct with Garuda (Perth). I received an email confirming my flights and also provided with the booking reference number. Attached to the email was a form for me to authorise Garuda to debit my CC, I filled this out and faxed back. To-date my CC has not been debited. I rang Garuda a week later and they advised, that the tickets are issued numerically (don't know how to read that). Now the "kicker" on the email is the following "Please note that this fare is subject to change until paid in full.' Does this mean that if the fares/taxes change I have to pay the latest price (are they holding on the payment to cover there back)? Thoughts?
