Trying to beat everyone to the plane and have everything done before anyone shows up isnt a plus in my book as a captain. It could be a signal to the others that I dont trust them to do anything. We used to have some wacko here that when youd show up, hed be strapped in already and sit there and watch your preflight flow. Wacko! Terrible tone right from the beginning. (He took an early out during COVID, and I am almost sure all of covid was worth it to rid outselves of this guy a couple years early
). I try to show up sometime before boarding starts so I have time to talk to all the FAs. I assume by this time the FO has arrived and done the walk around and the preflighting the inside. If they havent, It isnt a big deal. If they are going to be late Ill do all the preflighting duties time permitting.
