It is a simple contest. Just book your tickets ( I assume virtual booking, not real) and win a trip to the US.
Book now for the chance to win seats on their inaugural flight to Gotham City (includes attending the Batman v Superman worldwide premiere).
If you win, you and a friend will require eligibility to enter the US, the ability to travel around 19 March 2016, and an open mind.
