Some Great Promotions for Denver Fliers

If you're a Denver traveler, you've been lucky for the past few years - tough competition between Frontier, Southwest, and United has brought fares down as the three airlines duke it out. So, not surprisingly, when Southwest launched a new promotion targeted for Denver fliers, Frontier and United matched very quickly.

Southwest is offering a free roundtrip ticket after the purchase of a Business Select ticket, which is the airline's fully-refundable fare with perks such as a free alcoholic beverage, early boarding, and access to a faster security line. Frontier is offering 25,000 bonus miles (which is enough for some free tickets) for the purchase of its Classic Plus fare, which is similar to Business Select but offers some perk unique to Frontier such as free DirecTV service, and access to Frontier's new STRETCH seating that offers a few extra inches of legroom. Like Southwest's Business Select, Classic Plus is Frontier's most expensive nonrefundable fare.

United's is a bit more confusing. While Southwest and Frontier have attractive product names that they are promoting, United is showing off...fare classes Y,B,M,E,U,H,Q! These are the coach fares that aren't heavily discounted. For every purchase in those categories, United is offering a free roundtrip and is offering upgrades for the first purchase as well.

While all of these promotions are focusing on Denver (Southwest's only Colorado destination), the promotions from Frontier and United are available for any of those airlines' Colorado cities.
