Trying to book HND to the US West Coast flights with P2. We have similar mileage balances, so we planned to book separately and also use the Aspire card to hit the reimbursement. But right after P2 finished booking, when I got to the payment step on my end, it errored out and only cash tickets were available. The award inventory clearly showed >1 when I was booking.
Left with no choice, I cancelled P2's booking, and the award seat didn't return to inventory until several hours later. Not willing to give up, I tried again—booking two tickets directly from my account—and it went through successfully. What kind of magical feature is this..? No matter how many seats are in inventory, once any one person books one, they all get blacked out?
Just a heads-up: when tickets are issued separately and you run into this kind of last-minute seat lock, any later changes or refunds may no longer be on the same booking, so the steps and fees are handled separately for each. Especially with award tickets close to departure, don't make your itinerary too tight just to use up your reimbursement—and think ahead about the backup cost of a cash ticket.
