I like the DC-9s as well. 16 F seats for a plane that seats 90.. Great chances for an upgrade, plus the overhead bins will actuall fit carry-ons. Even better than the A319/320s. I attempt to fly them and avoid the crampped CRJs at any cost. Also, I flew DTW-ORD weekly for 6 months and most of my delays were ORD air traffic. I have had more issues with 757 and A320 when it comes to mechanical problems.
