Can you explain why it's that useful? I'm honestly trying to understand the problem this might solve. (I'm not in anyway saying this doesn't solve any problem!)
Let's say you want to see a particular event that happens multiple times (like a play) in your area.
This allows you to search for the best seats in every instance of that event so you can make the best single selection.
Oh, that's a good example, thanks! I followed the article but it had an example with sports and, unlike a play, I believe not every game is exactly the same. So, yes, it does indeed sound like something that solves a problem, I've had it before myself a couple of times with plays with short runs.
It also works well with sports, imagine a family trying to catch a Nets game. They probably don't care who the Nets are playing, they just want to get in the door as inexpensively as possible.
Full disclosure, I work at SeatGeek.
The same thing happens in baseball where the team might play 4 consecutive games against the same team.
I also didn't know about this, my lack of knowledge of American sports is showing. :)
