The idea that flight search platforms directly reflect the impact of local events on a trip is an oversimplification of their highest potential.
Their true full expression, their peak performance, is not to reflect events but to transcend these constraints.
I have seen families find flights to Sicily during Ferragosto, a peak period, at surprisingly low prices, by using adjacent airports and slightly shifted departure days.
The maximum potential of these tools lies in their ability to reveal asymmetric opportunities, regardless of the local atmosphere.
