Bagels is talking about the customer first policy. It allows at least 24 hours. If you purchased the tickets anytime on Thursday they may not be ticketed yet. Call reservations and either a.)ask them to switch the names (they might have to cancel and re-book the tickets, but within 24 hours there is no fee) or b.) cancel and re-book. There should still be W availability, but you need to check that before you cancel.
