You did read my post correctly. While I am certain, that this case provided very little input (I didn't mean to discourage anyone from contributing any data inputs, I just don't think that this particular case made us any wiser, since this was certainly the expected outcome and anything different would have been a very big surprise), I do still maintain that anyone who booked (or even re-booked) within the 2x miles promotional period and gets rebooked involuntarily (due to strikes, flight cancelations etc.) should still be entitled to 2x miles.
I know what information was communicated by some Aegean representatives, but there have still not been any such cases actually reported (unless I missed one, which I don't think I did). Whether Aegean credits 2x miles automatically in such cases or the passenger has to file a claim, is also something we still need to wait to find out for sure (as well as how Aegean will handle such claims, should any be made).
I have some data input that isn't exactly relevant, but it gives you some idea. I had 2 flights that I rebooked back during the lockdown. Both were cheapo P class economy tickets. The first got re-issued in Y, after which I didn't change anything again until I flew and I got the miles for the re-issued fare class. The second got rebooked into Q or J (again, for some, J is an economy fare), but I later successfully placed an upgrade bid and flew in business class. For this ticket I didn't get the miles for the re-booked Q fare (even though I made this re-booking myself online) but for the originally booked P fare!
So to me that is one indication, that the miles crediting system will, according to the circumstances, either utilize the original booking, or the very last re-booking, but not any "in-between" re-bookings. This is the reason why I can imagine it being "easier" for a ticket booked for the first time within the promotional period to get the 2x miles, than any ticket booked before that and re-booked within the promotional period (if both were to be re-booked again later).
