As CT hikers know, flights from Durango to Denver are notoriously expensive - often $270 for a one-way ticket. But a friendly former Durango resident who overheard me in a Cincinnati brewery discussing with my sister which town in Colorado I may be moving to next year had great news - nonstop flights from Cortez to Denver are only $59. The Cortez airport is about 60 miles west of Durango; when I hiked the CT two years ago the long, roundabout bus route from Durango to Grand Junction had Cortez as its first stop.
Note that on Kayak, Cortez does not appear if you are searching for Durango flights even if you click on "nearby airports" - you have to specify Cortez.
As always, it pays to drink good beer. And now beautiful but isolated Durango is moving up in my rankings ...
