Curious to know if my experience is alone in this. Last year, I flew Delta from ATL to FCO and sat in the first row of the middle section of Premium Economy, behind the bulkhead. There were four seats in the row, and many of us just kept our bags on the floor in front of us after takeoff and until they had to be stowed. The strange part, I thought, was that several people used that space to cross over from one aisle to the other during the flight. I didn't comment, nor was I rude to anyone, but I wondered to myself and my wife if this is considered normal? Is that space intended for passengers to cross from one aisle to the other? Curious about your thoughts. I am 6;5" tall, so my legs stretched to the wall, so I had to move them to let people pass.
