My guess is that people will become accustomed to this new process, just as they have to liquid limitations, removing shoes, etc. etc.
But, I was visiting William & Mary yesterday, having been invited to deliver a distinguished lecture, and at dinner with several other faculty members, the conversation turned to leisure travel. We all travel a good chunk for business, and we all remarked on the fact that we had increasingly been planning more drive-to vacations, and fewer fly-to trips, because air travel is just getting to be so unpleasant.
If enough people really *do* start cutting back on air travel for such reasons, the pressure that the airline industry will bring to bear will be significant.
