All passes will become available to the general public at the time of the Full On-Sale, February 6 at 10am PST, and tend to sell out immediately. If the ticket site shows passes as “unavailable” that means they have already been assigned to someone else’s cart, and the transaction is in progress.  Sometimes these transactions time out or don’t go through, and the tickets become available again.  The tickets are not sold out until it says, “sold out”.
