Sort of an abstract issue, but relevant for Madison, particularly with the growth of 50 to 100 seat aircraft in and out of Madison
: Interesting look
Northwest’s scope clause is, in fact, particularly onerous relative to scope clauses at other major airlines. United, Delta, American & US Airways can outsource (to regional airlines) aircraft up to at least 70 seats (US Airways can even outsource some aircraft of 86 seats). Continental’s limit is 59 seats, but can do a virtually unlimited number of those.
The issue at Northwest is particularly acute because Northwest flies smaller mainline aircraft than any other major airline. Northwest itself flies over 100 DC-9s (photo above). These geriatric aircraft (many of them over 30 years old or more) have just over 100 seats. Click here for further DC-9 data.
