That's why I think this SWA move has absolutely nothing to do with the state of Missouri other than it's another chink in the WA. I think they will load up the route for awhile and then cut back at STL like they did before because the loads just won't justify the frequency.
Hell, I've been surprised that some of our DFW-STL flights haven't been eliminated. Except at holidays, almost none of the flights are ever totally full.
I think the main reason AA still has the number of flights between ORD an DFW that they currently run, is due to the clauses in the pilot contract agreements alloting so many Captain jobs in STL. Those pilots are paid a pretty penny and to just have them sit reserve all month because of the limited flight schedule out of STL would be a total waste of money. At least by running revenue flights from STL-ORD/DFW they can then flow the pilots there to work flights that are full.
