I spoke to couple of ticket reps yesterday in person at an event at Centurylink field. The latest the tickets should arrive is tomorrow. I also have not received them nor gotten an email that they were shipped.
The told me that the reason they were late is because their vendor in the midwest ,that makes the tickets, shipped it out late to their vendor in Seattle that then mails the tickets to the Season Ticket holders. It has been discussed among the ticket reps of having some sort of ticket pickup party at Centurylink Field so we don't have to deal with this stuff. Hopefully that happens in the future.
