The Sustainable Flight Challenge (TSFC) aims to challenge the avia- tion industry by encouraging and accelerating innovation in the quest for a more sustainable future. TSFC is an initiative of Sky- Team, a leading airline alliance comprising airlines from around the world. In its 2023 edition, it takes the form of a challenge scheduled in the second quarter of the year in which 22 participating airlines implement the most sustainable solutions competing for an award in 33 different categories. This challenge represents a new step in the aviation industry’s journey towards a more sustainable future. .Green fuel: we will use SAF, an advanced biofuel produced from renewable materials. .Online check-in: more than ever, we are encouraging passengers to check in online. . Equality: we believe in an egalitarian future. Which is why the em- ployees on this flight have been assigned equally. .Efficient route: we have studied the most efficient and, therefore, most sustainable route with the competent authorities, and the tra- jectory will be MAD-AMS-MAD. .Local catering: fresh, certified products served in reusable con- tainers in order to minimise their environmental footprint. .Free of plastics: we have reduced the use of plastics on board. On this flight, the glasses, cutlery and food containers are biodegradable. 70
