I'm pretty sure the host team has to cover away travel in the playoffs still.
I thought so to at least if it was over certain mileage this is from but this from .. the 2021-25 handbook under playoffs....
So basically looks like they only get a little more of the gate because the host school has to bad the officials directly instead from the gate if visiting school travels over 100 miles...
Team Expenses: The NCHSAA receives 15% of the gross gate from first, second, third and fourth
round games. In all rounds prior to the regional championship, participating schools will divide the
remainder equally after applying the following expense formula:
(1) Where the distance between the competing schools is 100 miles or less, the visiting school
will pay its own transportation and meals and the host school will provide the playing facility,
ticket takers, security and balls at no charge. The officials are to be paid from gate receipts.
(2) Where the distance is more than 100 miles, the same plan should be followed except that the
officials are paid by the host school, rather than from gate receipts.
(3) All concession rights belong to the host school.
(4) Participating schools are responsible for dividing any deficit or net.
(5) The principal of the host school, or appointed game manager, must forward the financial re-
port and ticket accountability form to the NCHSAA within 10 days after the contest.
