Everytime I get an exit row, I get "Sky Priority" on the boarding pass, and zone 1. Works for me at the Sky Priority lane when I don't get an upgrade prior to check in. Silver exit row is almost like being Gold Medallion, without the milage bonus, and still a shot at gate upgrade. Silver may be not as good as Gold, but I'm digging it. Only 16 more segments to Gold for me. Not going to be a problem.
