Help! How to fly cheap from madrid to logroño??? what are some cheap spanish charters? thanks a million!

I've done that route by plane a lot of times and there are not really cheap alterantives,...but if you book right now ( I mean now) for october you can get something for September -October for less than 100€. By the way only Iberia flights to Logroño from Madrid.

Nevertheless, bus is a popular alternative and if you take the supra class one is pretty good (4hours though).
