I had a problem in the early March. I booked 2 BE award tix in December to Europe. Same flights (except one leg) but 2 different tix. One for me and one for a friend.

The tix I booked for the other passenger got cancelled and instantly reissued at less than half the mileage of the original booking somehow. It went from 150,000 miles to 60,000.

The next day my tix got cancelled all together. When I called delta they said that my tix was only on hold and that the time allowed for holding a tix had expired. This was not correct because I had an eticket number and it was over 3 months since the reservation was made. The call center was very helpful and got the ticket rebooked without a problem.
