Cons: "We landed over half an hour late. Flight attendants needed to move passengers to balance the weight on the small plane, and asked for "volunteers." When there were none, the FA stood in the aisle and said we just weren't going to take off if nobody volunteered. They should have just MOVED people."

Pros: "Charging at every seat is great."
