I got swept out. When I realized, only seat left was very last row next to bathroom. I complained and got 4,000 miles for the inconvenience. Given that I have no status and this is an award ticket booked through Continental, I felt this was very reasonable.

Few days later, a window seat opened up toward the front, so I snagged that. Interesting that right now the system will let me select an E+ middle seat. However, I am going to stay with E- window.
