I ran into SemiElite on the shuttle for the Tampa Airport Doubletree in October. We were discussing Continental's upgrade policies on the ride and he mentioned HoKeY fares, which ONLY a flyertalker would know about.
Most recently I ran into Spiff at the Atrium Crown Room Club in Atlanta on Friday. I had pre-arranged a meeting with Tolarian Wind and we were chatting when Spiff suddenly walks by our table.
N866DA has checked me in for my Delta flight at SFO on multiple occasions. He used to be the only person manning the Medallion checkin counters in the afternoons. I also run into Russ21ATL at various Crown Rooms in ATL all the time.
