I have the same issue and am due to be in the US in July.
Does anyone know how I can use my miles? I can't even give them to a friend without paying more than the points are worth!
I have spoken with Delta and Delta Vacations and neither of them will help, in fact they both refuse to help.
I am on hold with them right now for the fourth time this week.
Does anyone know anything I can do?
I guess I will just have to forget they exist
