My interpretation of the removal of the bonus ex-CH is that e>ticket/checkin/booking/everything has "worked" in the "home" market CH. If the numbers of e>"flyers" is not increasing dramatically any more and there must be some point at which e>services are "saturated", why offer a extra incentive to people for doing something they would do anyway? I also feel the "legal reasons" are an excuse but whether this is the case or not, handing out miles is at Qualiflyers/LX's discretion and I personally would not bother taking the matter much further for the limited gains. Personally, I prefer paper tickets (easier to endorse) and Qualiflyer Newsletters (nicer to read) and only take the e>options for the miles (saving QF/LX money too, I suppose). I would change back to paper if they were no longer offered.

I find the Qualiflyer programme quite generous/flexible compared to several others and generally try not to bite the hand that "feeds" me. I was once by ground staff many years ago, after witnessing "a scene" at the transfer desks in ZRH that there is a "place in the computer system" which can be used to describe customers as being "easy" of "difficult" (maybe proportional to the number / type of "complaints"??) I have no idea whether it's true, but as a "story" it may be worth bearing in mind.
