If you’re selling two tickets, they’ll always be sold as a pair.
Here are your options for selling more than two:
3 tickets – sell as 1 or 3
4 tickets – sell as 2 or 4
5 tickets – sell as 1, 2, 3, or 5
6 tickets – sell as 2, 4, or 6
7 tickets – sell as 1, 2, 3, 4, 5, or 7
8 tickets – sell as 2, 4, 6, or 8
When listing nine or more tickets, they can be sold in any quantity.
This only applies to reserved seating. If you have General Admission (GA) or lawn seats, these can be sold in any quantity.
