You mean reschedule, not reconfigure. Changing the arrangement of seats on an aircraft isn't going to help. Also, I think you're being overly optimistic about IE. It's not a task for an afternoon for a typical IE (although there would be some specialists with graduate-level degrees or lots of experience who might do well). Perhaps more importantly, the key is to do this in real time in a dynamic environment. Solving the problem in several hours doesn't do much good.
