Have to vote for the M80. The F100 is the only plane that I have actually refused an ou on. I had an exit row and it's definitely a better seat than any F seat on an F100. Sad to say, it's also the only one I've ever been offered an upgrade on. Why do I fly on it? It's the only thing out of my local airport (SWF)and I do like the convenience of a ten minute ride as opposed to an hour or more to one of the other airports. I also can usually get a ride so I save on parking fees which I pay out of my own pocket .
