I have the $450 amex qantas travel credit set to expire on the 6th June. It says I can only use it for qantas flights - mine was issued after they did extensions so I don't think I can use it for a hotel etc. I don't have any travel plans coming up that I can use it for. Is the best strategy still to book a fully refundable fare and then apply for a refund in a few weeks time? Any tips for ensuring that the fare is fully refundable? Having a quick look on a dummy booking I can't see where all the fare rules come up.
