Nervous sheep? Well yes I guess some are, but on the other hand, fares have not come down very much yet and the increased security at airports with the unwashed pawing through your hand luggage is not a pleasant experience.
Wonder when airlines will get their collective act together, and start treating passengers with RESPECT?
The so-called service from airline staff at nearly all levels is very poor IMHO, and has been for quite some time, in the USA anyway.
