I appreciate Punki's viewpoint. There was a time that I flew more than the airline crews, and my schedule was less well known in advance. There is an obvious need here to allow exceptions, such as First Class, High Status, VIP.
This is based on my assumption that the goal of the carry-on limitation is to allow more time for the security checks. I am hoping that in about xx days (maybe 60?) they will have decided on what the new screening requirements really will be, and they will have trained enough screeners to open more screening locations, and they can return to allowing the airlines to decide how much carry-on they want. (AA, for example, was in the process of investing millions of dollars in putting larger overhead bins into their planes for a competative advantage.)
