Over the years, I've felt like Southwest taxied faster than other airlines. Maybe it's just that I'm on WN flights out of airports where you *can* taxi fast and get cleared for takeoff in advance, whereas nobody's taxiing anywhere fast at the legacy hub airports.

My dad flew in the Navy early in his career, got out and flew commercial for a while, and then went back in to the Air Force. He claimed to be able to tell whether a commercial pilot was Air Force or Navy, but it's also possible he was just pulling my leg.
