My boss is a season ticket holder (2 seats).
He said he prepaid a while back for playoff tickets and got 2 seats, not his normal seats automatically allocated to him with no choice on what they were, but they ended up being better seats than his normal seats (more expensive). Then on Wednesday, he was allowed to buy up to four more seats wherever he wanted so he did that. Said he was then going to put the allocated from tickets from earlier on stubhub and actually sit in the seats that he got to select.
I imagine this is the way most season ticket holders are working it. So, two season tickets, parlayed into 6 tickets for each game.
