Round trip
Frontier is flying San Diego to Denver nonstop for $113 right now, well under the usual $255 this route runs. Ski season is ramping up in the Rockies, so it is an easy way to reach the mountains without a layover. At this price it works just as well for a quick weekend trip as a longer stay.
