Ideally, if these mergers do occur, KLM will drop NW and BA will drop AA. Otherwise, no government will
allow either merger to go through. The combination
of AA/BA (oneworld) with KLM/Northwest is too big.
My opinion is that none of these mergers will occur.
The DoJ and the EU just won't allow them and the
airlines' respective employees will put up a big fight.
Frankly, AA stands to gain little from owning NWA.
Apart from the lucrative Asia (pax and cargo routes)
AA would be getting a second rate airline, albeit w/
strong hubs in MSP and DTW (the MEM hub is not
of any importance really to AA, given DFW and
MIA), a fleet of a). junk jets that AA would not
want to operate, such as the DC9's, DC10's, the
727's, and 747-200's and b). newer planes that,
except for the 757's, don't fit into AA's fleet at
Northwest has made huge improvements in its
operating performance and has gone to highly
exceptional lenghts to clean up its balance
sheet. But, IMHO, it remains an airline that
has an image problem, flying geriatric planes
that will take 3-7 years to replace, and has
the least desireable hubs.
US Airways (alone), TWA, Continental, are
all doing something unique with their product.
NW has yet to differentiate.
