This is a question directed to any in the know about mileage plus award travel booking. I am planning to book award travel soon, but not sure if I can do a multiple destination type booking. I would depart HNL-BIL and return MSO-HNL both via DEN. I can opt for a r/t HNL-BIL-HNL but returning from MSO will save me about 300 miles of driving! So what's the verdict, can I book that with miles? If not, is there maybe a way I can trade the same miles for a nice discount? Thanks very much!
