•Does an airline in your country use decoration on its planes?
I don't know exactly but I remember some plane with strong colors when I have been travelling in the past. I can remember that colors of IBERIA, the main airplanes company in Spain, are whole white with three strips granat, red and yellow
•What decoration does it use? What does it represent?
I think that decoration of planes of Iberia represent the colors of the flag of Spain.
•Do you like it? Think of an alternative to it.
Yes, I like it but I would like it more if planes had more vivid colors because if you ride on a happy color plane you are not afraid do it so if you ride in a black airplane for example.
