I agree with javaboy's math - it is a good hypothetical of how short haul flights can be much more lucrative than low-yield long-haul flights.
But Busdrvr makes an excellent point also - shouldn't a very efficient airline be able to do both? Fly up and down the East Coast for 10 hours or so (roughly between 6am and 6pm) and then fit in an evening West Coast turn? Keep that airplane in the air something like 20 hours a day?
Airplanes are huge capital investments yet many airlines are content to fly them an average of 10 or 11 or 12 hours a day. Doesn't make sense to me. If you double the utilization, you only have to buy half as many of them.
Granted, the more expensive the aircraft, the longer they tend to stay in the air each day. 777s flying to Asia, Europe and S Amarica don't typically fly only 10-12 hours out of each 24. And cheap RJs don't usually fly redeyes (except at CO), so their utilization is probably closer to 8-10 hours each day.
