Ugh anyone with experience finding and booking TN awards, please chime in. I'm looking for PPTLAX next June. The date I wanted was available yesterday, but suddenly disappeared today. Is this something that happens quite often? One peculiar thing that's happened is there's now a ton of blocked seats on the seat map that weren't there previously. I've got an EF alert set, but I'm wondering if I should book an alternate date. I just don't want to get hit with a change fee if my preferred date opens up. So frustrating.
