I like not having a middle seat though. Everytime I've gotten the middle seat, its usually been between two people who hog the arm rests and cramp my personal space. I'll take a window or isle any day, and the 170/190 offers only those options. So I can see why a frequent traveler would enjoy the seating.
Midwest ran MD80s and 717s. The seating was A-C and D-E-F. Frequent Fliers on YX probably could always get the A-C side, so the 2-2 seating of a 170/190 isn't anything new to them.
