I can confirm that my ticket (purchased in Jan) for DXB-BOS was upgraded 20 minutes ago (at OCLI) for 57,500 from Y saver to J. That is the "old" rate.
I wish I realized this before depositing an additional 25000 miles into my account. Oh well, live and learn. Now I'll end up with 42,000 miles left in my account....not much I can do with that, but I guess I have 3 years left to figure it out before they expire.
