These "retirement" flights have had more than their share of incidents over the years. A while back a Northwest 744 captain got in hot water for having a friend in a WWII bomber form up on a final revenue flight going into MSP. A retiring American Airlines captain got violated for making a pass over Spruce Creek airport in Florida with a 777 on a ferry flight. A UPS captain in Alaska thought he was Bob Hoover on his last flight and did an "arrival demonstration". The feds, understandably, were not amused.
And, a retiring Deltoid had some extra paperwork to fill out after landing:
