A nice breakdown of ticket fees from Hardball Times.
Or look at that Mets fee, for instance. A $23 convenience fee for a ticket! That’s insane, right? Well, the ticket costs $455. That $23 add-on is just five percent of the ticket cost. Meanwhile, a cheap CitiField seat might have a comparatively meager add-on cost of $2.75, but that’s an increase of over 10 percent to its $20 ticket. (That said, it is pretty insane that the convenience fee there is more than the seat plus convenience fee in the nosebleeds).
