So I was saying this yesterday but I think a LOT of tickets have already been sold.
For example, this is the presale for New Orleans and from what I can tell it is one of the worst selling dates so far
As you can see there is a lot of dark blue and LOADS of seats available.
But the good news is on the same presale for lots of other dates there are only single seats and light blue sections
Winnipeg:
Houston:
LA:
And literally every other date with an interactive map. So either they've put more tickets available for NOLA presales than anywhere else, or everywhere else is selling like crazy
