When Thomas Cook Airlines Belgium turned 5 in 2007, it celebrated by commissioning Belgian comedian Kamagurka to redesign one of its planes. The result? A plane adorned with a long-haired superhero beneath the logo "Kamagurka Hairlines."
Warming to the theme, in 2009 Thomas Cook's Belgian branch unveiled its Mega Mindy livery -- inspired by a popular children's cartoon character created by the animation company Studio 100. The livery was created to advertise Studio 100's theme parks in Belgium and Germany.
This elaborate Swiss International Airlines livery depicting farmers herding cows through an alpine meadow was unveiled in 2006. Following it in 2010 was a flower power livery, adorning planes on the Zurich-San Francisco route. Flower power? Surely a few decades late.
Qantas has some of the most colorful liveries around. Back in 1994 it commissioned the aboriginal-themed Wunala Dreaming design for the side of a Boeing 747. Another livery was Yananyi Dreaming, inspired by Uluru (Ayers Rock) and the stories of the indigenous Anangu people.
Among the South African budget airline Kulula's quirky liveries is the Flying 101, with arrows pointing out the plane's various parts, and a mustache-adorned plane rolled out to mark the Movember charity fundraising drive.
In 2009, Korean Air created a livery celebrating its sponsorship of London's British Museum. The livery depicted an Egyptian golden coffin mask and an Anglo-Saxon helmet, among other items from the museum's exhibits. A helmet -- winged or otherwise -- yes. But can the coffin theme have helped the more nervous flyers onboard?
Taiwan-based EVA Air launched its first long-range jet -- flying between Taipei and Los Angeles -- emblazoned with everyone's favorite mouthless cat. Everything on the EVA Air feline flying machines is Kitty-themed, from crew members' uniforms to the coffee cups, head rests, toilet rolls and food.
Condor's crazy-looking Rizzi-bird livery was created by the late American artist James Rizzi to commemorate the German airline's 40th anniversary in the mid-1990s.

ANA's panda-themed livery, created to celebrate 20 years of the airline's flights between Japan and China, was unveiled in 2007. The image took 350 people 80 hours to transfer to the plane.

Berlin's coat of arms -- a brown bear wearing a crown -- inspired Germanwings' Bearbus livery, created to celebrate the launch of the airline's operations out of the German capital's Schönefeld Airport. Best not to think of the ditty about bears and woods when this big baby passes overhead.
Bangkok Air has adorned its aircraft with everything from flowers and umbrellas to cartoon characters. Some of its latest liveries feature the airline's mascots -- colorful planes with names such as Sky, Sunshine, Rocky and Daisy.
Known officially as the Salmon-Thirty-Salmon (it's a Boeing 737, get it?), the inspiration behind this livery was an incident in 1987 when an Alaska Airlines plane was hit by a fish as it was taking off in Juneau, Alaska. It's believed the fish was dropped by a passing bald eagle.
In 2011, an Air New Zealand craft got a rugby-themed makeover to mark the airline's sponsorship of the All Blacks rugby team. Painting the aircraft took more than than a week, with 14 painters working in shifts 24 hours a day. More than 700 liters of chrome-free primer and paint were used.
The world's largest plane decal, taking more than 400 hours to complete, was unveiled in 2012. A Hobbit-themed safety video, featuring characters from Middle Earth, was shown on the Air New Zealand plane, and cabin crew even donned pointy ears for the first flight.
