I have actually talked to one of the managers for the concessions at the Airport, and the airlines refuse to move over to the concourse where the club is, because they charge close to double the amount to be in the US Airways concourse. The airlines are complaining, and are trying to move to the other concourse. The only reason CO would move is when they are forced to, because they do not want to pay for the increase in rent that would come with a move. Also, if the airport was going to consolidate to one concourse (which granted they could very easily from a gate space perspective, especially once US stops flying GSO-LGA) they would have to redo the ticket counters to move all airlines close without having to trek across the upper level.
