DENVER (AP) - You've heard of ski passes. How about airline commuter passes?


As Frontier Airlines expands its service within Colorado, it is offering packs of one-way tickets to fly from Denver or Colorado Springs to its new destinations of Aspen, Colorado Springs, Durango and Grand Junction.

All travel must be done by June 30.

Travelers can buy six one-way passes for $594 or 10 one-way passes for $890. There are no blackout dates, and passes are transferable to another passenger before ticketing.

The passes work for flights operated by Frontier's Lynx Aviation subsidiary but not those operated by Great Lakes Aviation.
