Flew home on UA 563 ORD YVR Thursday night. Was on the upgrade list, name one had cleared so that left 11 names on the list. Door closed and we pushed back. Since I was sitting in E+ I could see all the seats in BF and also those seats in BF that no one sitting in them. Guess it was due to the laziness of the gate agents that they did fill those seats with those of us waiting on the upgrade list.
