Just got my invoice for next season. My price increased from $92 to $100 average per seat per game for row 2 center court balcony. (8.7% increase)
Price increased from $84 to $92 last offseason (9.4% increase).
The two seasons prior, prices went from $60 to $72 to $84, but I've also landed better seats each time so can't compare directly. I recall it would have been an increase no matter what each season, but can't nail down the exact percent.
I keep saying I don't know how much longer I can keep this up, but one thing I'm starting to really appreciate is how the benefits have really improved over the past 12 years, which has made it worth it for me. The on court shoot-around, road watch party, etc. are pretty cool events. I took a friend to the post-game shoot-around this year who had never done it before and he loved it. These cool extra benefits were nonexistent a decade ago back when ticket prices were in the $30-$60 range. I'm also still not losing any money overall when reselling my tickets, although my resell prices have definitely dropped in recent months.
