I flew my on my first (I think) CRJ900 today (flown by PSA) and was upgraded from 8A to First. While not complaining about the upgrade, when looking back a few rows I can see now I would have had more legroom had I remained in 8A. For my return flight I am booked in the second exit row (16D), and I'm now wondering if I would get more legroom there than in First, so am considering canceling my "requested upgrade." Is anyone able to compare the two? It's just a two-hour flight, so the putative service enhancements I would receive in F don't mean much to me, I care more about the seat.
