Risk is. I recommend or buy tickets with a tariff that allows you to change the departure date (with a penalty), or insure a trip from not leaving at any insurance company, and risk with the submission of documents for a visa.

Officially, the availability of booked or already purchased airplane tickets is not the only reason for the Consulate to uniquely issue or not issue a Schengen visa. You can refuse to issue the document for any reason, and the Consular employee does not have to cover them.

In general, Spain is a friendly country for foreigners, therefore the reservation of air tickets is enough to confirm their tourist intentions. You will also need to provide a passport with a copy of all pages, an internal passport, two photos, a certificate from the place of work, a copy of the work record book, a certificate from the bank on the status of the account, a copy of credit cards, a personal receipt for the purchase of currency, marriage certificate and the birth of children. $
