Frugal Travel Guy says that Delta is waiving the processing fee on mileage transfers in December. You pay just the 1 cent a point to transfer miles between accounts, without the extra charge. Discounts are great, transferring 30,000 miles usually costs $330 but would cost $300 with this offer instead.

Those for whom Delta is honoring the up to 150% bonus on partner transactions (the original terms of which included transferring miles) may have an outstanding opportunity here.

I still don’t trust Delta enough to believe I won’t have to fight for my 150% partner bonus, so I’ll probably take a pass on this. I may have to fight for the points I transferred into Delta from Diners Club as it is. But if you registered for the partner bonus in time, before the offer was pulled (and if you have a steel constitution), this one could be huge.
