So far (unless I missed something) AA has made NONE of the following "precise":
(1)credit card usage (or non-usage) to count toward EQD
(2)premium economy: (a)when will it start, (b)what amenities do you get
(3)"super discount" Y: all its "features"
(4)using (miles, SWU) to upgrade AWARD tickets to the next "class of service", (a)implementation date, (b)what is the next COS, Y to PE, Y to J*(?)
(5)J (used to be called F)--rumored (via JonNYC), but not yet stated (by AA)
(6)No more "hold" only "24 hour cancellation"--yet both of these are still in place(?)
I try to keep up-to-date on AA stuff (via FT), the "average" flyer would most likely be VERY confused by the NEW AA.
Maybe FT should have a WIKI for info we DON'T know.
