Saw a flag at the Denver airport that wasn't in the arrivals hall map, and the guy I asked about it went quiet
I was at Denver International last Thursday waiting on a delayed flight to Austin, so I had about 3 hours to just wander around. I noticed a flag near a service door by gate B42 that was not on the airport map or the directory boards anywhere. I asked a janitor about it and he said he had worked there 11 years and never noticed it before. When I asked a gate agent, she kind of laughed and said I should not worry about it. Then I looked it up later and found a whole thread of people claiming DIA has tunnels and rooms that do not show up on the blueprints. Is this just normal stuff in old airports that I am reading too much into, or has anyone else seen something at DIA that was not on the maps?
