The site has a new template that has been coded to provide a continually updating comparison of most of the Regional CodeShare Industry. User's can see the current total market share of each Regional, as well as the percent of total market share each CodeShare network, and specific aircraft type occupy. You will notice something interesting with the CodeShare Network percentages, which may help support a case for the US Airways, American merge.
The template also breaks the analysis down by fleet type to see which Regional's have the strongest position respective to fleets, which won't be a surprise to most. It is interesting to see the positions in the numbers.
