Hardly relevant in this instance. For starters, NWA was in far better financial condition than Delta was just prior to the merger, and secondly....the World Clubs were not what was causing NWA to lose any money. On the contrary, they were making money for NWA like most clubs do for airlines, which leads me to my point...if NWA was able to have self-serve bars, it makes absolutely no sense that Delta is trying to move away from them as the benefits for DL are barely tangible.
