From another blog:

Looking at DL's current schedules, it looks like they have uploaded the new MD-88 configuration into their schedules. It looks like the row numbers now match up by looking at the overwing exits. The rear galley has been removed, and two seats were added in the F cabin. The new configuration is 16/133.

Two routes that I have found them on include ORF-ATL beginning on November 3, and PHF-ATL beginning on November 15. I am sure there are also several others.

That PHF-ATL by the way is a route I'm very familiar with and in a way, its moving in the right direction. Originally we had 757s and 727s flying ATL-ORF, AirTran ATL-PHF, and of course we had ATL-RIC. I want to say all airlines combined there was possibly 26-28 flights a day between that part of VA and ATL.

Then ASA was sent into PHF with CRJ200s. That grew to 700s, then 88s in the summer season, then 900s and no more 200s and now 3 flights on Sundays are 88s and 737s with 2 weekday 88s in November. Right now in October there are Now, truth be told some of that is siphoning off ORF but for a while there there wasn't any mainline at ORF either but now its back to 7 MD88 flights per day.

All in all, just counting Nov 5 as a random day, there are 22 Delta flights alone from ATL to middle and southeastern VA (RIC-PHF-ORF) and of those only 5 are RJs (3 700s and 2 900s) and there are 3 757s and 1 320 in the mix in RIC but otherwise all 88. And by the way, non-reving in and out of those 3 cities is a pain with PHF being your best hope.

Its a step in the right direction and I don't like typing on iphone.... fwiw.
