DJK7: How did you know the pax next to you was a marshal - typically, they don't announce it. And the one you saw boarding a flight, same question - holster bulge, air marshal badge? I'd be interested to know...[/QUOTE]
The first one ( not the one I sat next to), I'm not positive about, but pretty sure. He was at the FC ticket counter while I was in line, he opened his wallet to show the agent and I could see a badge. There was also an airport cop standing there chatting with him. He and the cop headed towards security, I was about 2 minutes behind and I didn't see the guy there, I think the cop bypassed him around security. When I got to the gate, about 50-60 min before flight time, the gate agent was letting him on the plane. I couldn't tell where his gun was, but he was wearing loose "commando" pants with about 10 pockets scattered all over. I didn't see him after that.

On the next occasion, it was an originating flight, I was the first passenger to board, no one had gotten on the plane for at least 20 minutes prior to this. When I got on, there were two guys standing in the aisle talking, when they saw boarding had started, one took a seat in coach, the other one took the seat next to me in first. He was dressed pretty casually, but with a blue sportcoat that looked out of place. Big bulge on the hip under the coat, both times he got up during the flight, he caught the gun on the corner of the bulkhead. Once when he was returning to his seat, I got a clear look at it. I didn't see the other guy again, about all I remember of him was that he wasn't wearing a coat or jacket.
