The websites still has the old new requirements.
How do I become an Elite member?
A+ Rewards members who earn 10 or more A+ flight credits within any 90-day period or earn 25 A+ flight credits in any 365-day period will now be qualified for A+ Rewards Elite membership*
*Reduced Elite qualification levels effective 4/22/09. A+ flight credits are earned when traveling on paid reservations. Flight credits are not awarded for reward travel.
I think the message may have been an old one from the days before they reduced the requirements in 2009. It seems odd that they would increase the requirements for a program that is going to be phased out.
