This, plus the fact that the premium seats are sold on 5 year licenses. In effect it's a five year season ticket.
You could either buy them for 5 years or for life. But the point I am making is that if you stop paying the monthly fee, you are breaking the terms of the contract so they can pass your seat on to someone else. I'm not 100% sure, but I hope that is how it works!
