Shadow.. the payscale did have something to do with the orders being delayed
http://www.flyertalk.com/forum/Forum21/HTML/000407.html , but the strike is the main reason, or so says the local agents at the CTO in downtown SEA who are pretty well connected with the Boeing guys.
I'm going into SEA tomorrow for meetings and I'll be sure to look for any 767-400's. I did see one last week. During the strike, I saw as many as 7 jets backlogged for DL.
