I re-read all the posts in this thread, and also in the thread of the same name, that I started on Flyertalk. Firstly, my sincere thanks to all who contributed. Even though this was an emotional and controversial roller coaster, I hope this thread has also triggered new perspectives.
In summary, spanning this and the FT thread, we've seen several people confirm large and unspecified size companies in the USA and Germany own the miles in order to reduce travel costs, and that in Germany, the law appears to explicitly support this approach. We've had multiple input that confirmed that the number of such companies doing so has reduced over the last years, probably because of pressure to offer additional benefits in the then very competitive, good economic times.
We've also seen contributions in this thread that company owned (rights to use of) miles can have a positive side, if we're willing to think about the subject from a different angle.
Specifically, in post #63 of the same named thread in FlyerTalk, Flying Lawyer wrote "If you have the choice between jobs or miles (either for you or for you colleague next door) what would your decision be?". I personally think that that's a very powerful and interesting question, and I respectfully ask, including those who have been very critical of me in this forum, to ask yourself that question once again. It's a fair question, and the answer is simply either "job" or "miles".
For those that haven't read his full posting, I suggest you do, as he's a very credible, long standing member of FT, and he explained company ownership of miles in terms of saving jobs. You might not agree with it, but it's still interesting reading. Before anyone asks, no I don't know him personally.
In addition to the above, several people posted that their management looked at the possibility of company owned miles, and decided against it because of the huge task of managing this mass pool of miles, and because of the related controversial/emotional connotations. Yet, as we know from the postings of others, some companies are doing it, and statistically, and also based on my personal knowledge, (message #54 of the FT thread), it's more than the number of companies identified in this forum.
So, my point is, they figured out how to manage the sea of miles/points, and how to find ways to make the matter acceptable to their employees. .. probably different solutions for different companies. So, by definition, there are solutions, encompassing several different approaches. What the solutions are is a different discussion.
I thank the mods of this forum for allowing this sometimes heated thread to continue. I certainly hope that others have gained new information and perspectives from it.
My thanks to you all for your valuable time and input.
Best regards
Stuart
