I agree with flying1500!! If you can't commute same day on both ends which is a luxury. Preference an early show and commute the day before. It's less stressful. Be very nice and introduce yourself to the whole crew. Show up early to gate and be nice to agents. Treats and chocolate are always nice. If you are at the gate when the pilots show up try to meet them. Some airlines require listing before you show up. AA and WN and maybe others. Get Flight track app for your phone. Have a plan B and back up plan C.

If you ever have to bump someone because you have a higher priority, tell them face to face and apologize. Do it sooner than later so the bumpee can execute their plan B. I was bumped from a DL j/s once by young connection guy. He was standing 5 feet from me talking on the phone for 20 minutes then boarded. The agent told me that he bumped me and he knew it. I have no issues with the priority system, I just think it's effen rude not to let someone know as soon as possible.

When you are the working pilot do your very best to accommodate all commuters. Find room for their bags , get them a drink. If you meet them early let them know there will be a seat for them somewhere on the plane. Tell the agent "Please don't leave anyone behind and fill every seat" I try to make time to check gate area when boarding is almost done to make sure the agent is not denying a j/S or NRs for lack of time. This all enhances my own J/S and commuter karma. Things I love to hear.... "I commuted / Jumpseated on xyz airline ( and my own airline) and they treated me very well, they are really nice there" etc.

Commuting is stressful ,try to make it less stressful for others. What goes around comes around. Good luck!
