I'm 6'8 and 285 and have found it all comes down to leg length and how flexable one can be with crossing your legs and how far you can shift down into the seat.. A lot also comes down to if you can get the lap bar down far enough to click and lock so the attendents will clear you for the ride. Funny how many times a support group in the line cheers you on saying come on man you can do it, squeeze down more,pull your chest in.
