A "dummy" or temporary flight reservation, which is a document proving a confirmed ticket reservation without actual payment, is a legitimate way to illustrate your travel arrangements while applying for a Schengen visa. Dummy tickets provide all the details required to apply for a visa, such as the date, the route of travel, the passenger's contact and personal details, and an active PNR. Consequently, you can apply for a visa using one of these tickets for the lowest possible cost of just 800 or $10.
