Who is planning to ban all carryon and computers? I noticed that PanAm -- the small airline that laughingly calls itself PanAm -- has done this. But anything else is idle speculation and fear mongering. I have flown on six flights and two airlines in the past two weeks. And while I have been subjected to varying degrees of additional scrutiny and visual search of my carry-on bags, I have not yet been denied access to the terminal airside areas with a large shoulder bag, and a second smaller catch-all bag or duty-free shopping bag. I have seen other travellers rolling their somewhat larger carry-ons, and with them either a briefcase or large shoulder bag, plus purse if female. These people have had no problems at ORD, SJC, TPE or YYZ, the four airports where I base my experiences from.
I don't mind the extra scrutiny, though thought the removal of a plastic disposable razor was as silly as those who have had to surrender nail cutters and the like. Only in TPE was I required to turn on my computer, though I had expected this at all check points, so kept it on "sleep" for that possibility.
I agree with the notion of responsibility. In the past I have also opposed some of the excesses displayed by those abusing the carry-on rules, either by bringing an excessively large amount onto an airplane and expecting it to fit somewhere in a cramped coach cabin, or by those who stuff their bags in the First Class storage areas and then tromp off to the coach section.
So, please. Until you can prove that all carry-on will indeed be stopped, don't foment idle gossip and panic.
As for the assignment of Passenger User Fees for security, Congress mandated this as the responsibility of individual airlines, not airport authorities. The airports themselves have a large responsibility to ensure the buildings and land are secure airside, so I suppose you can say some of those fees are going to a side of security we don't see much of.
