I flew out of the Piedmont Triad airport in Greensboro recently to IAH on CO and a guy I was sitting with commented that CO Express was completely taking over and mainline was leaving soon. He was One Pass and likes the upgrades on the longer flights down to IAH. I checked travelocity and it appears that he was correct. The flight I was on was full but perhaps that isn't always the case and then of course there is always the question of yield. If CO can make more money putting the big jets somewhere else, that's what they are in existence for, to make money. It's just a bit sad for us aviation enthusiasts. I remember the CO Lite days when GSO was teeming with many CO mainline flights. I also noticed on this board and by press release that AA is pulling their two mainline flights to DFW also.
