Honestly, these flight search engines focus on a single aspect: the ticket price, and it's a misconception to think they reflect the real impact of local events. How can a flight site show the logistical hassles of a festival, like massive traffic jams in Cannes? To truly anticipate, specific information about the event is needed, not just a fare; talking to locals is much more relevant. The cost to the local community is never displayed, and that's what matters most to small merchants.
