I have a really early stop (always the first one off in the morning) on a very crowded morning bus (usually we have to stop letting people on, which annoys the crowd at the place I exit the bus, because even letting one person off does not make room for anyone new to get on) so I often will say, rather than ask, I'll be getting off soon, why don't I let you get in first so you won't have to get up to let me out.

Although most of the time once we start to fill up I go and stand by the door. Otherwise even if I can get out of my seat I would still have to crawl over under and through a bunch of people to get to the door. Given it is mostly students with backpacks that makes it even harder to maneuver my way out.

I guess I find a quick statement with the why I'm asking seems better than just staring off with questions/negotiations. But that is me. So maybe just I get off at the _________ stop, do you want to swap seats would work rather than what stop are you getting off at.
