With the notable expansion in Orlando and the decreased number of aircraft, there have been questions about where the expansion capacity is coming from. So I did some comparisons between the planned early March 2013 schedule and the March 2012 schedule. Some of the capacity comes from pullbacks at Milwaukee and Kansas City, although both MKE and MCI were down to a handful of aircraft by then. A fair amount of frequencies is coming out of Denver as well.

The comparisons I ran were all domesitc and were for the first week in March 2013 compared to the average week in March 2012. Here are the changes in weekly frequency in Denver domestic flights.

Net change is 164/week fewer domesitc departures, decreasing from 919 to 755 per week. That's 97 fewer Airbus flights, 5 fewer E190 flights, and 62 fewer Q400 flights.

The total capacity is not off quite as sharply because I didn't go as far as factoring in capacity of each flight. There are more A320's than last year, and all the 74-seat Q400's are out, of course.

Total nonstop domestic destinations in the March schedule increase from 58 to 59, but more of them are non-daily. For further comparison, I included 2011.

Although the rest of the Frontier network has obviously seen great change in the past few years, the Denver system has seen big upheaval as well.
