Me too same airline, same response ! showed my rapid reward card , told them I fly every week . The agent actually looked up my number to verify.it happened to be my 3rd flight that week.The good thing about southwest is that there is no assigned seating.it's open seating. so I actually try to make my self " spread across" the seat or put my bag in the seat next to me and avoid eye contact from people looking for " permission " to take the seat ! It's only hard if the plane is full and every seat is taken or I don't get the pre board ticket or am running late and there are only middle seats left.
