Applying for a visa?
Need a flight reservation for a visa, not a ticket?
Many consulates ask for a flight itinerary before they decide on a visa, and buying a full ticket you might not use is expensive. Flicket offers flight reservations with an airline booking code (PNR) from $14, but ordering is paused while we connect live airline inventory. The page explains how it works and what to check.
