738s, more pax capacity, more range, ETOPS certified, we can fit a good 20 more pax on to a 738, than a 320.
It is not that necessary, but it could help.
With the trips from SFO-LAX, trips operate every 20 minutes, by adding a 757, we can do 757 flights at the top of the hour, and at 30 past the hour, a 737, less flights, less planes wainting to take off, move almost the same number of pax, and do it with fewer flights, thus less money is spent operating it, and more revenue can be earned.
East Coast Shuttle, heck thats what they want to do with the US Airways merger, so why not make the flights that fly on 737s out of IAD shuttle flights.
Make good deals like $400 round trip from JFK-LHR for about 10 seats per flight, fill them, more pax thinks of deal, thus there is more business, more revenue.
The 763 seats about 205, the 777 seats 278, UAL could put them in with 245 seats and fill them. The flight to Tokyo, would be the conclusion of the round the world flight. BTW I changed it so it would go LAX, JFK,LHR, Delhi, HKG,NRT, 777 trip... LAX.
With the de-planing through two doors, I'm aware that Shuttle does that, but I want ot do it on flights other than shuttle. The de-planning is a pain if your in the back of a DC-10, and you wait for 20 minutes to get out, this allows for faster turn arounds, and the plane can be in the air faster.
