Wow, I have been placed in a MEGA pickle by this. I was advised over the phone (after 1 December) that my pre-December 1 flexi bookings with this program would be fine to split and change with minimal if any cost as long as the destinations/names were the same, if I needed to do it. Called up for flights coming up, as due to personal issues I have had to change/split the booking... advised that the change fee would be approx $165 one way, approx $220 the other way. This is only BNE-MEL and MEL-BNE too, mind you. There's no actual fare difference (in fact the return flight is cheaper...) I really hope it gets resolved by a call back in the morning, otherwise I'm in the hole financially over new year. Fingers crossed.
