I was on a regular -800 with old seats but new configuration last week DEN-CLT. I had A03 and went to my usual exit row aisle seat for a flight of this length (and had one of two empty middles next to me) but texting with a friend at WN and she told me it was a reconfigured one... looked at the 2-seaters behind me at the second exit row and they had as much legroom as I had. So did the row in front of the exit rows. I didn't take a look at the ones in the front as all the aisles were full with pre-boarders by the time I got on.
