Despite the intentions described above and the effort made by Genève Aéroport, the airlines ultimately make the decision and take the economic responsibility for an air link.
Opening a new route involves many stages and many criteria, for instance: market demand, client profiles, availability of aircraft, traffic rights, the role of alliances, operational costs, technical constraints, slots, etc.
The decision-making process can take some time. Genève Aéroport has contacts with all the airlines already operating at the airport as well as potential airlines that may operate in the future, and seeks to play a part in the process.
