DL has a very good J cabin, and based on all reviews on the seats, a winner. I think as DL slowly integrates NW, I think you'll see a focus on expansion. Look only at Brasillia, Angola, etc. DL has a major presence in Europe, Asia (esp with NW), now Sydney also. DL continues to expand into Africa. That expansion seems to be where DL's focus is now, and I think a wise one. Since the economy is down, if they can pounce on new routes, they might well strike some good bargins.
DL HOPEFULLY will start to expand cabin service again in both F and Y.
Unlike others, I don't have issues with DL folding the fuel charges into the price of the ticket. I think it is more honest pricing. Now, lets dump these other fees, bring channel 9, keep up the DISH network roll out...it's good!
