why aren't airlines buying 767-400's there's only been two airlines that have ordered it delta and continental,I think it's a great plane and will provide excellent proforamce for any airline,I know things are shaky right now and airlines can't buy new planes beause of the economic conditions but even before all this the 767-400 sales weren't great,if no new orders come in boeing might stop production,so why aren't airlines buying this great aircraft it dosen't make any sense?
