I've been FO/GM a few years prior and PM for the past year or so, and I really haven't really ever been hassled because of my age before. I've found DL agents and crewmembers to basically treat people the way they are treated. So I think Im usually pretty friendly and am treated that way in return. Of course there have been a few bad agents and all, but that can be expected. In a few rare instances I was carded at a CRC bar, but thats about all really. If anyone has been upset that Im a young PM, its has to be all the people passing through First on their way to Coach, wanting my seat.
