OK guys. I haven't been posting in a while but its nice to be back and see a lot of people being able to fly out of the States with AP, congrats to all of you.

I'm considering flying to my home country for Humanitarian reasons but it's really expensive to get flight tickets last minute, so my question is: Do they give you an specific amount of time to use your AP, for example do they give you 2-3 months to use it then after that if you don't get to use it, does it expire? Should I pay for my flight ticket now and pray that my AP gets accepted a couple of weeks before my flight?
