Skirtinstorms,
Before all the other airline folks jump down your throat and this thread goes totally downhill, I'll add my two cents, since there are some positions where business cards are appropriate.
FWIW, I carry cards in my current job as a corporate pilot, mainly to give to my passengers so that they can coordinate the return flight and any changes in the itinerary. I also carried cards at my former employer (IDE) since they provided a good way to encourage people to buy tickets during the startup marketing of the airline. I've also come across plenty of other pilots that have legitimate reasons to carry business cards.
Here are some of the titles that I've seen on various cards:
Pilot
Captain
Corporate Pilot
Senior Captain
Flight Officer
Chief Pilot
Director of Aviation
First Officer
Flight Instructor
Airline Transport Pilot
Here are a few "creative" ones that I've seen over the course the past few years:
Aerodynamic Systems Controller
National Air Transport Supreme Aircraft Commander (NUTSAC)
Flight Control Manipulator
Ramen Noodle Survivor
