At one time CLT might not have had issues with deicing, I don't remember this happening a lot during my early days, but it seems like the past few years it's an issue. If CLT wants to be a major hub and has had snow/deicing issues the past two or three years, they need to come up with a better plan. Maybe it's time for a regular deicing pad/area to better flow with the traffic getting out and off? Also, I've seen the FAA OIS website say that ground stops are airline specific due to ramp constraints. Maybe US needs to have a better plan in place to put this in effect when this happens next time if CLT can't come up with a better deicing plan?
