The old Business Class seats had gaps which were black holes for anything you dropped (airpods, cell phone, etc.). Not as bad with the new seats, but just be careful. Follow the above advice about avoiding anything heavier than a newspaper in the shelf in front of you, at the risk of it shooting out like a projectile right at you. Also +1 on requesting pajamas and a mattress pad when the FA first greets you, in case there is a limited supply. Remember the pre-screening for this flight, so show up at the gate a little earlier than you would otherwise.
