I'm doing some virtual spring cleaning and came across an electronic copy of the itin for my vacation last year... Including a DL 767 segment from SAN-ATL which I remember quite well (and if the A.Net member from France who sat next to me reads this, feel free to drop me an email, sorry I didn't get your name!)... But there was also an MD-88 segment from ATL-DTW, which I honesltly can't remember anything except the gate we boarded from.
To try to jog my memory, I pulled up the seat map for Delta's MD-88s on Seat Guru, and wait...hmm... my seat (17A) was the 3-seat (A/B/C) side of the aisle. I thought it was A/B then D/E/F on the DC-9 derivitives.
I Pulled the seat maps for AA's MD-80s and NW's DC-9-30s (both of which I have had the pleasure of flying) and both are as I remember them.
Is this an airline choice or does it have something to do with the newer versions of the DC-9 series A/C?
Either way, what is the reasoning behind the difference (If any )?
By the way-- and I haven't searched for this answer yet, so please ignore it if it's already been discussed, but: Why doesn't NW operate MD-80s? They seem to be happy enough with their DC-9 fleet that on the surface it seems like it may have been a logical jump at one point in time (Isn't the "true" MD-80 even on the same certificate as the DC-9 as a DC-9-80?)
