This morning on a shuttle from BWI to MHT, the FA announced a new rule that no items would be allowed in the seatback pocket during takeoff and landing. She also told a woman in the bulkhead that she had to put her book in the overhead.

It sounds like just a case of an FA making up rules as they go along, but I wanted to check with FT to see if this is in fact something new. I don't take SW often, but no one mentioned this on my trip to TPA last month or on my return from MHT.
