If the above is true, it seems that the problem with making changes/redeposits is not that PMs have been abusing the system by tweaking their intineraries, but that DL IT is unable to replace the award seat back into award inventory. If DL IT was able to replace the award seat back into the proper inventory, the same amount of seats would be available despite making little (or large) changes to your itinerary. So the question really is: Why can't DL fix their IT issues??? I am sick of "the merger" being the reason for DL's IT problems.....
