I typically try and get front row on flights, or at least the row next to an actual exit and I only take hand luggage. If I can get my hand luggage and get off first I get to passport control and get out much quicker than people who wait and end up at the back of the passport queue, and even further ahead of those that do baggage claim.

I can easy save 30 minutes if not more doing this. Obviously its not going to work every flight but it works more often than not. It's particularly worthwhile if you catching a taxi at the other end as you can short cut the queue at smaller airports.

However I don't see the point if you have way down the plane and/or have checked bags, other than leg cramps.
