Thread: Need help with C. Unsure what to do next.

Generally speaking, eight consecutive closing braces means you're doing something badly. It seems rather bizarre to have this sort of structure going on, and in fact it prevents you from what you want to do, since there's no way of getting to the code for the economy section from the code for the business section should that section be full. It's not as though you're really doing so many different things here -- no matter what menuselection2 comes out to be, for instance, you always then give menuselection3.

All in all, this seems like a job for flags -- rather than having separate blocks of code for each possible set of choices, just set selected_class = business; or something similar, and then you can easily adjust if full.
