I don't mind people getting things out the overhead before they get off, BUT:
-if you are staying on the flight, please do NOT get things out of the overhead or block the aisle until the passengers that need to get off do so.
-"Young children" does not include teenagers. Please don't argue with the attendants about boarding early because you are traveling with teenagers. (Yes, I've seen this happen.
-LISTEN to the instructions about overhead bins. If the flight attendant tells you to put your coats with your person because the flight is full, do NOT stuff it in the overhead bin. In addition, do not get riled up when someone (usually a flight attendant) pulls out your jacket and asks whose it is so that other people can put their carry-on in the overhead compartment.
