Question for those of you who've been here a while. Why do our MD-88s have a 3x2 configuration rather than the 3x2 in the DC9s, MD90s and everywhere else?

I'm trying to find if anyhwere they've posted a seating chart so I can see what our 88 will look like with 150 seats. I see other airline charts and the current 150 seat MD90 chart. I can't imagine what we'll find back there once we remove the aft galleys and shed light on the disco area.

But why? I know someone will say its for voyuer reasons when scoping the gear but as one who has scoped the gear I didn't have that luxury. And the people after of me we're not happy with their view either. It was an all around lose lose situation.

Speaking of the 88, here is Delta's first 88 after the cockpit was circumsized and I guess moved to a safe location until being put in a museum.
