I think PAX will love the "C". The middle seat is 1" wider than the others. Non-metal fuselage, so the humidity is higher, like the 787, so more comfortable. A lot of nice features for the PAX.

I fly a lot on DAL...I don't like the 737s, or the MD80s...I think I would like the "C" a lot better. The Compass 175s are very nice, especially the business class seats and the large bins...larger than the DAL 757 I was just on.
