I tried to book an award ticket with Lifemiles but I got an error message (possibly related to credit card authorization) and the transaction was not completed. I tried to book the same award again on the same flight, but the award inventory is gone (probably because of my initial attempt to book). Lifemiles is now showing "sold out" for the date I want to book. Does anybody know how long it will take for the seats in question to be reinstated as award inventory?
