The plans all sound good, but you aren't operating in a vacuum. With the Open Skies agreement to Europe, everybody and his brother is going to be flying transatlantic. A decade ago, US carriers were stronger than their European counterparts, that situation is now reversed. (Note how the agreement wasn't done until now.) With European carriers covering the high end of market, and new service from truly low-cost carriers covering the low end, there won't be much market left for the US legacy carriers.
