OK...I would have hubs in the U.S. in the cities of Chicago, Newyork, Miami, Atlanta, Detroit, San Francisco, Los Angeles, Seattle, and Boston. I would have flights from each of these hubs to fly to every city over 100,000 in population. I would fly with all Boeing aircraft. If an aircraft has 100% load factors on every flight, then I would switch to a larger plane so that there would always be room for expansion. For International flights I would use the A3XX from Los Angeles to all of the Major cities around the world within the A3XX's range. All of the seats would be First class (With the same fares as a coach class fare.) All of the seats would be next to either a window or an aisle with lots of legroom. For international flights, The seats wouls also fold back 180 Degrees to fold into a bed. Whew!
