Well, I read your post as if you were saying there is a difference if the original booking date is within the promo-period or not. To me there is not.

For this promo, a ticket with either original booking date within the promo period (let's call this ticket A) or a ticket with a rebooking within the promo period (ticket B) both are valid.
If ticket B is rebooked after the promo-period and it is self-evident that it leads to losing the promo, I claim that is is just as self-evident that ticket A would lose the promo, if rebooked after promo-period.

My opinion is that both A and B will lose the promo if they are rebooked now. But I also believe nothing is self evident, and therefore all posts reporting actual earnings are of interest.

The reason why I am bringing this up is that your post can be read as you are discouraging member Resolution to post, by disqualifying his/hers contribution. I, on the other hand, think it is a valuable contribution and that the community ought to embolden posters with very few posts.
