Does this really need any explanation? Who likes inefficient airlines that put you off schedule and potentially cause you to miss connections? The answer is no one, and least of all me. I am currently waiting for a flight and every ~25 minutes they make an announcement that the flight is delayed another half hour (we're up to 1:30 now). Luckily we're on vacation with no further connections, and we're passing time at the bar. But really, I'd prefer to be at my final destination so I can drink a beer there.
