I am for a NW/AA merger. Of course, the Pacific routes are very lucrative, but I think also the Memphis hub, and even the Detroit hub. I think MSP will go. The aircraft don't bother me that much since Boeing would gladly trade some 737's for the Airbus and DC-9's. Also, NW is rumored to be interested in the 777-100X for the DC-10, which would fit into the fleet nicely. The 747's will also be eventually phased out and replace with 777-300ER, etc. I bet Boeing wants to see this happen since the last time AA merged, they got 20 757's out of it.
The KLM tie-up is also nice and since BA and KLM are rumored to be in talks, it could be very intruiging (sp?) globally.
Also, if this does happen, I forcast a new livery for AA.
P.S. Welcome to the forum!
