The rent on the SOC building in DFW is 1500 dollars a month. It is currently undergoing renovation and will be a up to date, state of the art facility.
Over 30 years ago airlines had more then one dispatch offices, that just didn't work and I don't believe it will work today.
I do believe there will be more then one simulator training center as the current facilities can't handle it all.
If there was an accident or incident, in DFW, Parker could walk across the street and be on the scene in the ops center. A plane ride to PIT does not make sense.
