Oh, and then we don't even talk about ferry flights. Evildoers.
BTW, what costindex do you guys fly most of the time?
We have apolicy of 16 for the 737-500 and 12 for the -700.
Econ climb, cruise and descent. Cost savings over index 30 appeared to be €15 per 1500 NM. Those savings tok also into account the added mainenance cost of longer flighttimes. Go figure.
