Great suggestion at the end, please look to Europe or Australia for the model. CNBC: Airline Executives Urge Airport Security Overhaul Airport security needs to undergo a radical overhaul or else passengers will become further disgruntled, lines will grow and terminals will be overwhelmed, airline executives said Tuesday at a global aviation conference. "We simply can't cope with the expected volume of passengers with the way things are today," said Tony Tyler, director general and CEO of the International Air Transport Association, the airlines' trade group. ...James E. Bennett, who used to head the Washington Airport Authority and is now CEO of the Abu Dhabi Airports Co., said that if the current immigration and security procedures remain in place as more and more passengers take to the skies, airports will run out of terminal space to hold all the lines. Many airports have already undergone multi-million dollar retrofits to house additional security and there isn't additional room left. The ultimate challenge may not be developing the technology but having multiple nations agree on uniform procedures.
