Good arguments guys, but the fact is that a Middle-Eastern airline has been doing this very thing for some time.
We can get on here and give our very learned opinions backed bu years of experience, but we are in a unique position to talk to a company that has done this very thing an marketed it actively as a selling point.
What has been their experience?
Has anyone flown with this carrier and what were their experiences using this self-help basis in Business/First Class?
