I know we have at least one SCP on the theme of airline flights where anomalous things happen in midair, but I don't think any of them have focused on the alienation in the boarding/disembarking process, and this one does a decent job of alluding to that. Nice implementation of my idea, too.
One small nitpick: when I suggested that the conditions would read better phrased differently, I meant that they should all be reworded that way, not just the example I used. Now they look even more inconsistent.
