I wouldn't be surprised. There's rumours on this board of aegean crediting miles on fares where none were due. However, I wish they would have added a "on tickets booked after [date]" disclaimer. It seems it would be more fair that way.
We will have to wait and see, I suppose. It seems someone is wrong here, either AC or aegean. I suspect it probably has something to do with the recent move to place Tango on all international fares.
