vc10 said:You're looking at historical data? Given the recent entry into service of the E170 and the delay in production of Form 41, I suspect you're seeing data that reflects ramp up costs. Which isn't to say that you're wrong, just that you may be wrong to rely on the Form 41 data released thus far.

You're right, I'm using 3rd quarter data which is the latest available from BTS. Presumably there is still some "ramp up" affect, although less than the 2nd quarter where the Emb-170 data was somewhat "off the chart".
Since deliveries stopped abruptly late in the 3rd quarter, the crew staffing level is high compared to mainline, which affects the personnel cost per flight hour (the Emb-170 is the highest we have on a per seat hour basis).
One oddity is that the daily utilization of the Emb-170 actually went down from the 2nd quarter to the 3rd. It had the lowest utilization of any aircraft type, which obviously affects things like "ownership" cost per hour (and per seat hour).
Still, there are things like fuel that aren't subject to any "ramp up" effect. There the Emb-170 is higher per seat hour than all but the 767 and over $1 higher than the 737's.
The only area where the Emb-170 enjoys an advantage on a per seat hour basis is maintenance, but even there it is not the lowest - the A320 series is.
