DENVER - Frontier Airlines is waiving change fees and allowing passengers to change travel plans ahead of a winter storm impacting the Rockies, Plains and eventually the East over the next few days.

The airline is allowing customers to make one itinerary change for travel to, from or through Chicago Midway, Des Moines, Indianapolis, Kansas City, Milwaukee, Minneapolis, Omaha, and St. Louis from February 21 - 22 as long as origin and destination cities remain the same.

The waiver is only for tickets purchased on or before February 19. Changes must by midnight February 22 and travelers must complete their travel by March 1. Customers who reschedule travel after March 1 will have to pay any differences in fares.
