Commercial aviation (SWA, Alaska Airlines, etc) deaths per 100 million passenger miles traveled (2009): 0.0077
Total motor vehicle (Mercedes, BMW, Porsche, Audi, etc) crash deaths per 100 million vehicle miles traveled (2010): 1.1
Pedestrian (Belleville, Bates, Nike, etc) deaths per 100 million miles walked (2008): 1.43
Bicyclist (Specialized, Schwinn, Huffy, etc) deaths per 100 million vehicle miles traveled (2001 estimate) between 3.7 and 12.6
General aviation (Cessna, Piper, Gulfstream, etc) deaths per 100 million vehicle miles traveled (2004 estimate): 13.1
Motorcyclist (Suzuki, Kawasaki, Ducati, Harley, etc) crash deaths per 100 million vehicle miles traveled (2010): 24.4
So flying commercial is the safest way to travel. Driving is vastly more dangerous, but still second best. Walking is a little worse. Cycling is considerably worse. General aviation is worse still, and a motorcycle is the most dangerous popular way to get around. Still, at 24.4 deaths per 100 million miles traveled, riding 15,000 miles a year for 60 years would still only give you a 22% chance of getting killed on your bike.
