Air France is hosting an "Upgrade Challenge Campaign" featuring its original mobile game app, "Cloud Slicer." The campaign runs from January 19th to February 28th.

"Cloud Slicer" is an action game in which you swipe to cut clouds as they fly by. Each month, one person who achieves the highest score during the campaign will have the chance to upgrade to business class.

To commemorate the introduction of the new business class, Air France held an "Upgrade Challenge" event at Kansai International Airport and other locations late last year. Many passengers competed for the highest score, with the chance of a seat upgrade. The event is currently available on YouTube, where you can also watch footage of the redesigned seats.
