BTW, the more HHonors points you transfer to an airline, the (slightly) better the exchange rate gets, so if you transfer 25,000 MMR to DL then to HHonors for 50,000 points, that will then be worth 10,000 UAL miles, meaning that for your total of 150,000 miles you could get 60,000 UAL miles total as long as you transfer in 25,000 mile increments.
