75N v. 755 First Class Seating
 

I am confused with NW's designations for their 757 fleet. My DTW-SEA flight tomorrow is supposed to be a 755 with 22 F seats. When I clicked on the flight status button on the NW website, it indicates a 75N with only 14 F seats (which means I'm in the last row of F rather than 3rd from last). Anyone know which aircraft is flying the route? Also, the 75N with the smaller F cabin is not among those aircraft pictured/listed on the Seat Maps page of the website. What's the story. Thanks.

75N and 75R were the designations before NW expanded the F cabins to 22 seats. 75N became 756, and 75R became 755. For a few months, all four types were flying, but the conversion was pretty quick, and the 14 seat cabins should be long gone (good riddance!).

The difference between the types is the door configuration--the 756 has 3 doors and 2 overwing exits on each side, and the 755 has 4 doors on each side. so the exit rows in coach are different, but in F, they're interchangeable.

i've run into the 75N designation a couple of times since the switch, but haven't seen the 14-seat cabin on any of those flights. You should just get the 756.

so yes, in the early days of the CO alliance, it was often easier to upgrade on CO. :-)
