Just curious as there's always a risk of being reseated due to the moving divider when selecting an eco seat very much near the front of the cabin...
It happened to me a few days ago on a CRJ1000. I was seated originally in 2A and got pushed back to 3A, which is now showing as the first row of Y. it seems to mess up the seating system somewhat, by the way. When I try to change from the 3A that I have been pushed back to another one (say 3C), the 3A seat shows as unavailable. I have not tried to see whether it corrects itself overnight as I am happy with the window seat so I would not want to change it at this point.
