For my holiday travel: SYR to ORD - in e+, e+ full. ORD to SEA - in E+ in a window, middle empty, aisle another elite.
on the way home was a segment run. booked e+ from SEA to ORD, but opuped to C. ORD - PIT in e+ and it was full. PIT - IAD - no e+ (CRJ 700 config w/ f and e-). IAD - SYR in e+ and it was full.
On 2 of my segments it seemed like being a lowly 2P mattered, the rest it was all the same. Kids behind me were talking about the roomyness...I felt like turning around and saying "these seats are supposed to mean something."
The rest of the year they've been pretty good though. It seemed like the people around me in e+ weren't even MP members!
