Our plane didn't get to Dallas until after we were supposed to leave on it, so we had a late start to begin with. Then, thunderstorms in northeast Texas prompted them to reroute us on a different jet route, for which we had to sit on the tarmac waiting for a while.
My third flight of the day, from Newark to Syracuse, was late, too, but not late enough. I landed around when it left, so I didn't have a chance of getting there.
