Wow - interesting link - sounds like a very fine tuned and economical logistics network. Real key is minimizing mode changes and intramode transfers. I'm willing to bet that Boeing is shipping those fuselages for a small percentage of what Airbus pays to ship their A380 wings. (Which are probably bigger and a more outsize shape than a 737 fuselage anyways so not really a fair comparison) Mind you they have had time to work this out and more importantly volume to work out the bugs and spread the fixed costs.
