We sometimes did that back before the rule. But it was more to be ready to go rather than make money. Now that I'm in charge, I don't keep them trapped more than I have to, but the game is the ground stops with an update in another hour. Then at the top of the hour, we might get a wheels up time an hour later. Meanwhile the passengers disperse. Then ATC decides much earlier that we are released, so now we have to round everyone up, board and go.
