Il convient d'abord de noter à cet égard qu'aucun élément du dossier ne suggère que, lors de la conclusion du contrat de services de marketing, le gestionnaire de l'aéroport ou le Land aient envisagés et a fortiori quantifiés d'éventuels effets positifs des contrats de services de marketing allant au-delà des seules liaisons aériennes visées par ce contrat, ou d'un point de vue temporel, allant au-delà de l'expiration de ce contrat.
It should first be noted that there is nothing to suggest that, when the marketing services agreement was entered into, the airport operator or the Land ever considered, still less quantified, the marketing services agreement's possible beneficial effects on air routes additional to those covered by the agreement, or the possibility of such effects continuing after the agreement had expired.
