I don't know of any heavy business travelers who get paid by the hour, so it's a moot point to most. If it takes me three hours door to door or eight hours, I get paid the same, so any delay or additional time requirements takes away from personal time.
What I'm doing is a lot less travel in general (more Webex and con calls) and if I have to get on a plane, I try and make it a day trip.
Unless the airlines start complaining about water bans and such, it will be much more difficult to get TSA under control. Chertoff and company could care less if you have to spend an extra half-hour on the front end and another on the back end to take care of your toothpaste and check bags, and they could care even less if you are comfortable on a flight.
I doubt if the airlines will get too out of line, since half are in bankruptcy and the other half is paying off government loans and whatnot. It's pathetic but it is what it is.
