Fair enough. I'm just a little disappointed in Boeing for building the 767-400 and 757-300 in the first place, it's the kind of thing McDD would have done in their last days (MD90, MD11). I think it's also known as flogging a dead horse. Sales for these new stretches are kind of bearing this out, esp the 757-300 (thank god for Arkia and Condor, eh?).
If Delta are having industrial relations problems with the introduction of the 777, they should probably sit on their hands and wait it out (or solve the dispute) rather than commit to old but expensive technology to solve short term capacity problems. Surely they could find a few more TriStars on short-term leases then buy 777s?
