Talking about the 'dematerialization' of the impact of local events through flight search tools is an oversimplification; reliable information and accurate data are too rare resources to rely on blindly.
These platforms show prices, not the complexity of an event that can make a neighborhood impassable or cause public transportation to disappear, like when the July 5th stadium hosts a big match.
One must always do in-depth research to know if the raï festival will block the entire city, because budget surprises can happen quickly.
The real work is to anticipate hidden costs and logistics, not to rely on a price list that doesn't tell the whole story.
