I called UA and they moved me to the seat I wanted on the second leg. However, the website is still showing me in the original seat.
Oddly enough, after I called and they moved me to the seat I requested it is no longer showing as available on the seat map. And if I look in ExpertFlyer seat map, the seat I wanted is now occupied and the seat I was originally assigned and still shows in my reservation is showing as available.
I guess I actually have the seat I want but the web site isn't showing it for some reason. We'll see what happens when I check-in on Friday.
