Why do airlines seem to overbook flights so often, especially when they end up having to pay extra in rewards to passengers who give up their seats?

Question

It just seems like it happens so often, and airlines will sometimes offer you three times the price of the ticket just to stay a few extra hours. Seems like it’d be easy to just…stop selling tickets once the plane is full??

It’s cheaper to give out a voucher which will expire and also forces the user to buy more of your services than it is to let a seat go empty.
