Ugh, I don't know if I can republish any announcement on Deltanet.
So let me rephrase it - despite what the Dow Jones Newsire said, there are no plans to retire the MD-88 or MD-90. They are the "workhorses of our domestic fleet."
The 100 new 739s are to replace domestic 752s, 763s and A320s that were to be retired over the next 7 years.
