All airlines with origin in Catalonia or Spain use their own identification. Iberia, the oldest airline from Spain, uses a logo that consists in the letters I in red and B in yellow together, and the square dot above I has a crown.
Vueling has a Catalan origin, but anything of its image shows it. Its distinctive colours are grey and yellow. Their airplanes tail is dotted in grey.
Clickair has different type of blue for its corporative image. Its logo is an inclined airplane-shaped S. It seems to be formed by broken pieces of ceramic like Gaudi’s trencadís.
There is no one airline decorated with a Catalan symbol or motif.
