Kulula-air.com is a low-fare 737 carrier based in South Africa. The airline started in 2001 and recently took delivery of a new 737-800 with an unusual paint scheme.
Dubbed "Flying 101" it isn't the typical Kulula logo-jet.
Someone there clearly has a sense of humor. The entire airplane is covered with details about the plane, including arrows pointing to the more interesting parts.
"The big cheese" describes the captain's window. An arrow points to the aircraft's registration, calling it the "Secret code."
Even the lav is pointed out, with the description, "Loo (or mile-high initiation chamber)."
The black box, seats, stabilizer and rudder are also pointed out and include a bit of clever commentary as well. I think we can all appreciate a marketing scheme that doesn't take itself too seriously.
