Finman, what a spin meister you are. You must have worked at Enron or was it MCI-Worldcom. NWA was losing billions the same time as all the other legacies(along with some LCC's) and yet NWA management refused to go along with necessary fare increases. NWA management is a bunch of knuckleheads,like you, who need to be replaced with managers with some common sense. The management at NWA flew the airline industry right into the ground.
I don't want to spend too much time on it, since you seem to have it drilled into your head that your anectdotal memory of NWA not matching selected fare increases is the reason for the demise of the entire airline industry. I don't want to go back and reconcile the reasoning behind every decision, as I've explained how pricing decision are made, in general, in previous posts.
If you really wanted a bogeyman as it relates to pricing, it would be the Simplifares initiated by Delta in early 2004 that on their own have cost NWA between 100-150 million in annual revenue. Those fares put caps on one-way business fares and removed the saturday night stay requirement for discount fares.
I'm not sure what I'm spinning. I'm just trying to bring a fresh perspective on some areas of airline finance that may add some clarity to the discussion.
