As indicated in recital 39 of this decision and acknowledged by Belgium [130], SOWAER is the vehicle created by the Region and placed under its exclusive control to develop Wallonia's airport infrastructure and place this infrastructure at the disposal of the airport management companies in question.
Dès lors, la Commission ne peut exclure, en application de l'arrêt Altmark, que la subvention de la Région pour des services liés à l'activité aéroportuaire constitue un avantage.
