i sovled the armrest problem
last few flights i was on in cattle class (besides mooing as i got on), i simply raised up the armrests and held them in place with my elbow until the other contestants got the picture. we all had a nice comfy ride. not so much for the sprog kicking my seat when i leaned over and spoke nicely to the parental unit telling them "that needs to stop". also longer and wider than many i try to make room for my fellow cattle, but on one flight my knees were right in the back of the seat in front of me and when they tried to lean back there was nowhere to go. sorry.
