I think he was saying, let them know BEFORE boarding (if possible). It’s not a bad idea. I usually try to keep an eye out and have a quick talk to the agent so we can avoid someone getting left off for a weight restriction. Obviously not every problem can be avoided, but it’s a lot easier to work some magic 40 mins prior to departure than 10 mins when everyone is trying to close.

I agree though, that if you are just non-reving, then no need to check in with the cockpit. Glad you’re on, but as a D2, unless you have some good rumors or a joke to share... go take a seat.
