If you live in Cairns then you’re going to get the best deal. You can fly directly from Cairns for $269 return. If you’re flying from Melbourne, you’re looking at paying $458 return which is still pretty damn good.
The flights have to be from March 2020 until March 2021, and you’ll need to select the $0 return option when booking. Super Nintendo World doesn’t have an exact opening date yet, but it’s going t be opened before the Olympics in July. You an head here for the deal.
You’ve got until Monday, 3rd of February at 11:59 AEDT to book your flights (they could sell out quicker).
