I bought 4 season tickets this year ($999 per ticket, 200s). I got them pretty close to start of season so they have to be about as bad as any season ticket holder that pays that price could have. I figured I'd go to half the games, sell the rest, and see if it turned out to be a good deal or not by end of the year. I just sold the last of my tickets for regular season, so here are the results:
Spent $999 on tickets, so that is average cost of $22.70 per ticket. The actual 'face value' of each ticket varied from $10 (first pre-season) to $43 (heat/lakers) and added up to $999. I used the tickets for 20 games, and sold tickets to 24 games. The games I went to had a total face value of $437, and to just buy those same tickets from reseller market online would have cost me $567. The games I sold had a total face value of $567, and I sold those tickets online (combination of online 3rd party resellers and direct sales to people) for net (after taking out all the fees and just counting cash I got) for $756. So, in total I ended up paying $244 for the 20 games I went to, which is $12.44 per ticket, compared to what it would have cost me to go buy those tickets online would have been $29.08 per ticket.
Of the 44 games, 25 of them you could probably attend for less than what season ticket holders are paying face value for tickets, but then theres about 12 that its a wash, and another 7 that were worth a substantial amount more than face value that offset all the ones you are taking a loss on.
Overall, Hawks season tickets turn out to be a pretty good deal, although dealing with the selling of all the extras make it more hassle than its worth unless you are having fun with it or attending well more than half the games.
I looked at the Hawks "Flex Plan" as well. If you only got a flex plan for Heat, Lakers, Celtics, & Knicks games, then I think that could turn out for you slightly better than buying any other way, but its still overpriced for every other game where you can buy from a season ticket holder taking a loss on the 25 games going for under face value, and for the other dozen games since the flex cost is still double to triple the season ticket holder cost, you can still end up getting tickets for those games from 3rd party sellers cheaper than direct from hawks.
And I don't comprehend why anyone would buy tickets for hardly any single games ever for Hawks from Ticketmaster/box office direct.
I have a lot more data, but thought maybe that might be interesting to someone...
