There have been discussions on a longer range 767-400 for quite a while. It would help on an L.A. to Europe market. I don't recall where I have read the discussions but I do stay up on Aviation Week & Space Technology and Flight International (as well as about 10 other aviation periodicals). It is felt that while the 767-400ER is good for Delta and Continental, others have found the range to be a little less than they would have liked. Specifically, I have read comments that if the -400 has the range of the 300ER, then there will be more buyers. Lufthansa by the way, said it was the 767-300ERX (a longer range derivative of the -300ER under study) would be the great transpacific aircraft. I misquoted the article in my earlier comments.
