People don’t seem to know how to use the overhead bins or take too many carryons. I’ve had to rearrange people’s suitcases for them, or put mine several seats away, or have the flight attendant take mine. It’s really annoying.

There’s also impatience. The later I board the more likely I am to be standing there a long time behind people futzing around taking their time to get situated regardless of how many of us are waiting.
