The simulation is not that far off.  Yes flying at a lower altitude will
allow the A/C to fly a bit faster but not enough to make much difference
trips made per day.  The turbines are even less efficient at higher
altitudes, but fuel consumption is much lower.  The higher the flight, the
less drag and that is the biggest factor with fuel consumption.  I knew a
former Braniff pilot who told me that on flights between DFW and HOU they
would get as high as possible and then start into an immediate descent.
