I was not even aware of this promotion, and was pleasantly flabbergasted when the 2 points from the (AirTran) sky posted in my account.
Did book 2 flights right on my birthday Aug 23: One completed Sept 25, the other Oct 9, and got the 2A+ yesterday Nov 8. It could have been the 10 weeks.
...... Ah! Just checked my email, did get a promotion happy birthday email, still unopened till now, from Airtran. Now I am going to be greedy, and wonder if that promotion is per flight, and I am going to receive another 2A+. Too bad my birthday was not between Sep 13 and Nov 14, otherwise I would have received 6 A+ for booking and completing one roundtrip economy during that time of double A+ promotion... he!he!
