More clarity is needed on the mechanisms that determine the price of airline tickets, particularly for routes to and from Sicily and Sardinia. This is the view of the Italian Competition Authority (AGCM), which has announced the launch of a discussion with the European Commission to further investigate the issue, also in light of comments received from airlines after the publication of the Preliminary Report. The aim is to promote the comparability of fares and improve competition in the affected markets, providing consumers with greater transparency. As the Antitrust Authority points out, the air transport sector is comprehensively regulated at the European level, including with regard to price information. However, a critical picture emerges from the Authority's fact-finding survey: the lack of transparency in prices and ancillary services makes it difficult for passengers to find their way around the various offers, increasing so-called “search costs” and reducing awareness in purchasing decisions. One of the main issues concerns additional services - such as seat selection or baggage transport-  which are now a major revenue item for airlines. According to data, nearly half of travelers purchase at least one extra service over the basic fare, and it is precisely these costs that can raise the final ticket price by as much as 400 percent. Antitrust stresses the urgency of introducing tools that allow users to clearly and immediately compare all price components, including optional ones. Greater transparency, in fact, would stimulate demand mobility and push companies to compete more effectively on price. This is an issue that is particularly keenly felt with the arrival of summer. According to an analysis by Codacons, in June alone, the cost of domestic flights in Italy increased by 38.1 percent compared to last year, with a 32.1 percent surge compared to May. An increase that, combined with ancillary costs, makes regulatory action to protect consumer rights and ensure fair conditions for all passengers even more urgent.
