My 64 credits were also reduced to 32. I called A+ Rewards this morning and was given the discount code and cert numbers for the upgrades over the phone. Like everyone else I was told to book the airfare and then call within 24 hours of the flight to use the upgrade certs (if space is available). I'll have to be careful and only book flights with lots of FC seats as these typically sell out really fast on Airtran because how cheap a2b upgrades are on Airtran. It's a bit of a roll of the dice that would have been good to know going into this but 2 free tickets is still a bargain!
