Maybe I'm too fussy, however in the past year, I have sat in 15+ long lines of mainly CO planes lining up to take off from IAH's two SE/NE runways, on days when the weather is pristine. This after opening a new E/W runway on the north side of the airport, and repaving another. I get the whole wind thing, etc., however has it occurred to the planners at CO that their connection banks are overwhelming the IAH system. I feel sorry for the lone AA or US flight that gets caught in those lines.
And for the poor connecting passengers who offload a COEX flight in one of terminal B's western banjos, and have to dash with 30 minutes to their flight in the eastern concourse of terminal E, that's a pain and heart pounding dash. It is starting to remind me of Atlanta, which I go out of my way to avoid connecting through.
I love CO, I'm just starting to wonder about the efficiency and ease of IAH.
