But it's not clear from the mergers I've been through in this industry that there is much synergy you can achieve. It is extraordinarily difficult to put airlines together. I was on a conference call with Continental Airlines Chairman Gordon Bethune recently, and he was saying this might be a golden opportunity for the folks who aren't merging. The airlines that are merging are going to be very busy just trying to keep their airplanes in the air. It is havoc.
Airplanes look the same on the outside, but they are completely different inside.
Maintenance programs differ. The procedures pilots use differ. People have different computer systems. They have different flight-dispatch systems. They have different pricing systems.
