as to how much it costs. Because you have to pay the difference. Jetflex is dearer than jetsaver, therefore the price to upgrade will be less.
I don't have a clue about FF though, sorry. I aren't in FF because all the flights i ever get to anywhere are the cheapy ones. You generally can't get points on them, so not worth it.
