This question already has an answer here:
I'm an international student currently living near Chicago. Tomorrow I have an appointment to get a French visa, and I have a question about one of the requirements.
According to them (http://www.consulfrance-chicago.org/spip.php?article657), I'm required to have a travel itinerary: "2. travel itinerary: we recommend you to make a flight reservation and not purchase your airline ticket until you get your visa."
Does this phrase mean that I'm supposed to book a ticket before I show up at the Consulate General, or that it's just a recommendation and all I need is to know my route?
I would call the Consulate General, but they are closed today.
