Airline: Germanwings (take two)
Theme: Park Inn partnership
Germanwings emblazoned the words "Sleep well" on an aeroplane painted to mark the airline's collaboration with the Park Inn budget hotel chain, although the checkered design seems bright enough to keep you awake from 30,000ft away.
Whatever you think of its suitability, the livery is certainly not one you'd forget in a hurry. The design became an instant hit with plane spotters, partly because anyone lucky enough to spot the plane could win a free hotel stay and flight simply by snapping a picture of the aircraft and emailing it to Park Inn. Whether a pastime such as plane spotting should be encouraged in such a way is a debate we'll leave for another day.
