Barcelona-based Vueling, which was only launched in February 2004 but is making a name for itself in Spain, is another quirky low-cost player on the publicity front.
Its latest efforts have seen it running a contest to name its new Airbus A320s. A remarkable 20,000 people sent in their suggestions, says Vueling. The full list is on the carrier's website, but our favourites are: "The Vueling Stones" and "Ain't no Vueling high enough".
Another of the carrier's A320s is now named Connie Baraja. What makes her so important? She's the carrier's two millionth passenger.
