You really no nothing about Frontier's situation in Denver.
And what's up with bringing up United Shuttle? They only had 5 routes from Denver! Boise, Las Vegas, Phoenix, Salt Lake City, and Colorado Springs.
Frontier was one of only 3 airlines to show a profit during the first quarter. Not only that, but in the month of September, Frontier made a profit while United and other airlines lost BIG time.
Frontier's profits continue to sour every month. Thanks to Frontier, United fares at DEN are not as bad as they could be.
United has ignored Frontier over the years and simply monitored there growth, that is all. They have not done any drastic moves to take away passengers from Frontier. They let it be, and let Frontier passengers go to Frontier, and loyal United passengers to stick with United.
Yes, United does compete with Frontier. But tell me.......since when did competition pose a problem for Frontier? Never.......
By the way, some FYI for you. Most business travelers who are loyal UA customers and gave Frontier a try simply went back to United. The fact is Frontier attracts leisure travelers while United is the opposite. United's fares are obviously higher than Frontier's, but United provides many many many services that Frontier doesn't such as more connections, more amenities, etc. Fronter has low-fares and little service and definately not nearly as many connections as United.
They target different niches. By the way, Frontier has filed a law suit against United Airlines twice already for anti-competitive actions. United tried to kill Frontier but during the past 3 years, they've backed off and learned to accept Frontier.
As a result, United is not a problem for Frontier.
Frontier has other problems to worry about such as new low-fare carriers moving in such as Spirit Airlines which starts service from DTW and FLL this Thursday.
