The idea that flight search engines ‘realize’ the impact of local events reduces a complex challenge to a simple price fluctuation, which is a too limited view for true travel optimization. An event like the Festival of Lights in Lyon is not just a more expensive plane ticket; it’s a city saturation that affects the atmosphere, taxi availability, and neighborhood tranquility. Focusing only on displaying fares on a platform like Skyscanner ignores the total asymmetry between what the tool shows and what the traveler experiences on site. The real challenge is whether we want to fully embrace the energy of the event or avoid it with surgical precision, to reach the summit of the desired experience. For example, showing up in Seville during Holy Week without a detailed plan, just having seen a good flight price, guarantees a frustrating experience of crowds and inaccessible services.
