1. Be the last on the plane.
You’re not going to get anywhere any quicker by being on the plane first. And if you get on last, you might be able to sneak into a better seat than the one you were assigned — when was the last time someone checked to see if you were in the right seat?
2. Avoid lines for cabs by going over to the departures area.
Plenty of people take cabs to the airport instead of from it. Why not leave through the departure area and snag a cab up there rather than waiting in line down in the arrivals area?
