I recently boarded flight AA61, a 777 bound for FRA from DFW. Check-in was fine with no hassle, but once I reached the gate for boarding, there were police and security everywhere, and all down the jetway. They were pulling over EVERYONE and asking them questions. They said it was a currency check. They asked me how much money I was carrying, and what forms I had it in. I told the officer I wasn't carrying any cash or travelers checks, just credit cards. She looked at me funny, and pulled me into a room that was connected to the upper part of the jetway. She then began to ask my why I wasn't carrying any money, and what exactly was I going to be doing in FRA. She asked me if I was coming back to the US, and when. She wanted to know where I was staying and who I was staying with. It seemed to be more than just a currency check.
Well, we boarded the flight, and I had a seat in 12A. Then some officers came on board and escorted a man off for questioning. The man travelling next to me showed up in his seat 12B and we started talking about the currency check. He said that he passed by the same room I was in and saw a man. He said he paused for a moment and glanced inside and the officer told him that he needed to move on because he "didn't want to hear this..." (referring to the man inside the room).
Then we were delayed for quite some time, but after everything, we took off for Frankfurt, without the man they escorted off the plane.
What the hell was going on? Seems a little much for a currency check. I mean, really...asking everyone about their money?
