I've managed to pile up about 300k UA award miles for a trip for two on Business Saver awards to Europe. I don't really care which city we fly into or out of, as we plan to see most of the continent over the course of a month. What I do care about is quickly finding Business or First saver award availability on convenient dates without having to search flights to a dozen cities for the trip over and flights from a dozen cities for the trip back.
