Just got of the MSP to AMS flight and saw a new tactic to get an upgrade. I was in 16G and a couple were in 16 H and J. An hour into the flight, the guy in 16H had his seat reclined and the guy behind in 17H pushed his seat a bit forward. I guess it may have been a hint for 16H to put his seat up. A few seconds later, 17H slammed 16H's seat forward. I thought, are you kidding me, what a jerk. Why didn't he ask? There were some words exchanged and the "pink dress" flight attendant came to investigate and took Mr 16H away. A couple minutes later, Mr and Mrs 16 are moved to BE. Evidently, Mr 17G didn't like this and stomped to the galley. A few minutes later he too was moved to BE. At least I got to move to 16H and had the two seat row to myself
