[1][2] A $100 hamburger trip typically involves flying a short distance (less than two hours), eating at an airport restaurant, and then flying home.
"$100" originally referred to the approximate cost of renting or operating a light general aviation aircraft, such as a Cessna 172, for the time it took to fly round-trip to a nearby airport.
However, increasing fuel prices have since caused an increase in hourly operating costs for most airplanes, and a Cessna 172 now costs US$95–180[3] per Hobbs hour to rent, including fuel.
[4] In Perth, Western Australia, a similar mentality resulted in the 'Rotto Bun Run'.
A group of pilots who had run out of hot cross buns on Good Friday decided to fly to the closest open bakery on Rottnest Island.
