On a slightly different situation. Had chosen a window seat in the exit row for ATL-UIO. I was "upgraded" to EC. But I wanted the exit row window not an EC window. Could I have done anything to keep my exit row seat? I didn't know I had been given EC until the GA scanned my OLCI boarding pass and gave me a new one. I'm concerened it will also happen on the return and want to prevent it if I can. THX.
