Here are the maintenance fees...and they depend a little on how many seats you hold...
Seats in Sec 1 & 13, the best sections right at midcourt are $450-500 ea
Seats in Sec 2, 12, 14, 24 (the other secitons between the end lines) are $300-350 ea
Seats in the rest of the lower bowl and a few prime seats at mid-court upper bowl are $130-150 ea
Seats in the first few rows of the other upper bowl sections that are between the baselines are $100 ea
and all other seats (literally 1/4 to 1/3 of the arena) have NO maintenence...
So....if you are buying season tix now, it is highly unlikely you are going to even be able to land season tix in any of the sections that have a maintenence that's more than about $11 per ticket - so you are fairly fortunate.
I have very nice seats and give each year to support my alma mater so the "maintenence" is no big deal to me since I am giving that much already...
In the 15 years or so they've been doing the current plan for maintenence I have actually heard very few complaints.
Schools like U of I, UK, Duke, etc...require the guys who have the best seats to give upwards of $250K per year!!! The BU fans really don't know how good they have it!!
