Don’t get mad — get online. United has launched a dedicated page on its Web site listing routes which are more likely to have seats available for award use at saver levels. The site, http://www.united.com/milesaway, lists 50 or so routes on which seats remain available for the following month, as well as a few for the current month. As might be expected, most routes tend to be less popular with award travelers, but a few traditionally high-demand routes are listed, including a few to Hawaii (Kona, not Honolulu).
