Transportation Security Admin.

Problem: The wait time in lines, and the contingency of flight departure times.
Possible solution: The administration should look at the amount of luggage a passenger brings, and break down from "Carry On", to "Check In". Let's begin with the time spent in line. Everyone is funneled into single lines regardless of carry on or check in. Why does this matter? Time efficiency at the Electronic Article detection systems stage. People who have items with them should be segregated and placed into a line of their own. People who come prepared i.e. no belts slip off shoes etc. should not have to wait for the lazy ill prepared passenger. Hence fast or "ready line", "medium or elderly, disabled line", and then the lazy american line. Now will this simple, seemed solution to said problem divert the ignorant person away from the ready line? No, probably not. Can TSA make these persons aware and misuse of the ready lines yes, send them away to the mid level lines and back. Signs should be posted if you are ready, "Come on in Berlin", if not there are other lines to choose from. From my experience in travel, I do not have the patcience for the unprepared traveler and wish that TSA would get on the ball, step up to the plate and say, "Hey if you are ready to come through detection, step on up. The idea of showing up 1 to 2 hours in advance is rediculous. We may as well have chimps running the operation. Is it me or do TSA low level employees seem a few happy meal toys short of a happy meal?
As far as flight contingency. The idea of having specified lines only makes the process much easier on non busy flight departures.
