Right. DL knew the capabilities of the MEM hub before I was alive? Are you certain about that? Please. Let's actually discuss what MEM was before the 1960's... They had a couple of mail routes which crossed at MEM, like the tags to LIT and KCI. If you actually analyse the patterns of service (feel free -- there are timetables available online), you'll see pretty quickly it was no more of a hub than Dallas Love was with its tag service to Fort Worth Meacham & Amon Carter. MEM was nothing more than a glorified train junction where a north-south line happened to cross an east-west line. Even DL felt that they were operating a railroad -- their timetables were still printed in train schedule format... That's the typical WT response we've all grown to love: Don't actually address what's been pointed out in his own flawed arguments like the DC9's from NW somehow giving DL magic insights into the profitability of the MEM hub, or how flying tag flights thru MEM gave DL an idea of how a real hub would perform. Instead, turn the discussion to something about what challenges AA faces, even though this is the DL forum. When you can actually discuss the topic *and* the airline who this forum serves, let us know, OK?
