In 2016, coinciding with the launch of the second daily service of the Emirates A380 in Barcelona, we created a raffle on the airline's Facebook to celebrate. The idea was to design a treasure hunt experience, and we made it happen by hiding two A380 aircraft scale models in two emblematic places in the city. During the day of the competition, we published clues so that fans could progress and find them and win a trip for two to any Emirates destination of their choice. The result, a high level of engagement and involvement in networks that translated into hundreds of comments, likes and shares.
