Now, before you all jump on me, please let me explain

I'm currently working away from home with no access to a game computer during the evenings. So I have only time to fly during the weekends and you can imagine that my wife wants her part, too.
Currently I'm flying WB at an average of 2 hours per weekend (overdid it a bit yesterday but hey, it was the first time since two weeks

).
I did participate in the AH open beta and am very interested in opening an account here. But for my usage, the flat rate (as much as I love flat rates) is to high.
So my question is is it possible to have the iEN pricing scheme over here as
alternative to the flat rate? Or some reduced "weekend-only" flat rate account (I think in the direction of $15)? If not, that's fine with me, I'm not whining - just asking questions

Dancer out.
