A good deal but not always accepted by airlines
I had a chat with Tamir about his proposal. I didn't experience the offer to the end but it looks serious. The only issue is that it goes against most, if not all, airlines policies and user agreement. In my case, the user agreement for Air France/KLM Flying Blue clearly states that resselling traveler miles is forbidden. Seems like a trustworthy business, but you could be exposed to consequences from your airline.
