Crew have their own bin space in the closets, the issue is that crew bring a ton of bags. There was a crew member on a flight recently that had 5 items, more than 3 rollers in volume. I'm not explicitly blaming them, I know reserve is a tough spot where you don't know if you're going to Canada or Cabo, but it seems to have gotten a bit out of hand recently.
Wow! I have never seen that before. That seems like way too much baggage and would take up a lot of space. I am surprised that is allowed. The bag I saw someone try to move on United would have been hard to tell that is a crew bag and it was right above their space in business class. I am just surprised the American crew escalated the issue to a point where someone needed to be removed. It sounds like their needs to be some training.
