Sat in 13F 3 weeks ago ATL-DCA, and it was a great seat. Regular window, tons of leg room. The FA sits in the awkward aisle seat and he/she will have to 'invade your space' to arm/disarm the door, but that's it. It's way better than 12 A/F which are some of the narrowest seats I've ever sat in due to the exit door protrusion.
