If you want to make the case for adding additional safety procedures (no distractions during take-offs and landings) then you have to actually make the case. It's not enough to just assert that they seem minor if the benefit would also be minor. How much do you think this policy would reduce deaths?
Taking simple steps to be more aware of your surroundings when something dangerous is happening seems self-evident to me. Please let me know what flights are you taking and when so that I can make sure I'm not on the same plane.
My next flights are B6 1191 on 2024-01-25 and B6 1192 on 2024-01-28.
Most people don’t read the safety card or pay attention to the safety briefing either.
My rule of thumb is "know where the exits are", and "know where the life jackets are" if flying over water. Those are the bits that differ the most plane to plane -- seatbelts are consistent, clear paths during takeoff and landing are consistent, oxygen masks are consistent, but I want to know where the exits are and how to float.
