You just have to meet the courier rep and you may or may not get an evelope of papers to deliver at the other end. That's it. Oh yes, take your seat on the plane. You might be disappointed that you are getting that plane ticket and have VERY little to do, other then fly.

The only waste is the early checkin they request making you wait for the rep to show up at either end. Not nice when it is at 3 AM for a 6 AM flight to the Orient.
