1. The subway system signage in NY should be replaced by LCD or projected displays. At one point, we got off a J train because the J train said "all passengers must get off". There was a sign to take another train, on the weekends, down to where we were going. So we got to that platform, only to learn that this other train wasn't the right way to get there on the weekends.
2. How hard is it to do the plane reassignments in storms? I could imagine it's all done by computers, and I could also imagine it's all done by hand. Our plane has been diverted to Baltimore, instead of landing here - does a human say which people get which planes in a situation like this? Does a computer suggest alternatives? There are hundreds of flights to keep track of, but how much planning is automated?
