While looking at the NWA fleet, one can't help noticing the fact that they are the only major US carrier who don't operate the 767 in any of its variants.
UA, DL, USair, CO, AA all have 767s.
Why did NWA never order the 767? Was it because they were formerly concentrating on Asian routes (as Northwest Orient), and the 767 wasn't suitable for transpacific ops? Or is there some other reason ?
