These are just part of the 38 total to be operated under US Airways, correct?

Yes and No. 11+32=43 so where are the other 5 going?

All growth, or to replace 170s moving to the Frontier operation?

Aug 07...
37 E-Jets for USairways...58 by 4Q 2008
5 E-Jets for Frontier....17 by 4Q 2008

Total of 119 E-jets and 230 total aircraft in RAH fleet by end of 2008.

Okay...that didn't answer my question.

Are 170s being pulled from Airways for Frontier and being replaced with these 175s, or are these 13 additional growth airplanes?

I know that at least some off the 170s are going from USX to F9 and being replaced with 175s

The problem is that the 175's we're adding to USX are also supposed to be replacing 145's we're already flying for them. Those 145's are then moving on to the CAL operation. I think the rumor mill is kicking up that these 13 175's are going to be replacing the 135's we're pulling off the line in '08 for Delta.

buddy of mine works over there at chautauqua and the rumor he's heard is that the airline won't be operating anything but 170's sometime in the future (maybe next two years)...just wonder what that'll do for the american flying.

Hopefully, go to Eagle so those folks don't have anything else to complain about.
