Okay, so even though I would be flying the same flight/route from Frankfurt-NYC, I would have to cancel the part of the route from London-Frankfurt and thus pay cancellation/route change fees? I was just hoping that if I let them know ahead of time, it would just be as if my flight started in Frankfurt instead of London--I figured it wouldn't be a problem and there wouldn't be any fees just because I would still be using the same number of award travel miles either way and I would also be opening up an additional seat for United for the London-Frankfurt flight (I'm sure theres more to it but that was my thought process). Just out of curiousity, would my ticket be cancelled as soon as I missed the flight out of Frankfurt? What would happen if I just tried to board in Frankfurt?
