You needy people asking for free upgrades
When I smile sweetly and tell you that I will have to check if there is space in Premium or First, what I am really thinking is, “Have fun in Coach, bissssh.” I know this is a telltale sign of a needy person, and the LAST thing any cabin crew ever wants to do is create more work for themselves, or their coworkers. It is actually against the policy of many airlines to upgrade passengers for free. As always though, the inflight team leader has jurisdiction after the aircraft doors close. So, it can happen, but upgrades will never happen if requested as a complimentary addition.
