A confirmed booking for air travel is a mandatory requirement for most Schengen Visa applications. This documentation serves as proof of intended travel dates and itinerary within the Schengen Area. An itinerary typically includes entry and exit points, demonstrating a clear plan for the duration of the stay. For example, a round-trip booking showing arrival in Paris and departure from Rome, with internal travel arrangements, would satisfy this requirement for a multi-country trip.
Providing this documentation increases the likelihood of a successful visa application. It assures consular authorities that applicants have concrete travel plans and intend to adhere to the stipulated travel dates. Historically, this requirement has been implemented to mitigate risks associated with undocumented travelers overstaying their visas. This documentation helps ensure efficient border control and maintains the integrity of the Schengen system.
