Aena sincerely considers it a matter of good fortune that Ryanair, given its operational quality and efficiency, is one of the major airlines at Spanish airports. Contrary to what Ryanair's public statements imply, the airline is not obliged to use Aena airports: it uses them at its own will, and above all, because, in accordance with its emphatic objective of profit maximisation, it is in its interest to do so. No supernatural demonic force compels Ryanair to be one of Aena's biggest customers and to sell its tickets to more than 60 million people travelling to and from Spain.
