Volaris names its aircraft after contest winners. In 2010 the airline announced its “Put your name on a Volaris’ plane and get free flights for a year" contest.
Contestants had to answer the question: What would you do if you had a Volaris’ plane for a year? According to the airline, "Our jury will choose the twenty one (21) most original, creative and fun answers as winners. The prize will include the right to to put your name on a Volaris’ plane and a Volaris’ Pass to get free flights for yourself and one travel companion during a year to any of our destinations."
The pictured Airbus A320-232 XA-VOV (msn 3524) arriving at Las Vegas is named "Valerie".
