The success of the Columbus Blue Jackets in 2016-2017 has led to a record number of season ticket renewals and new folks buying packages. All of that goes a long way to making sure Jarmo and John Davidson can run an NHL franchise.
Friday August 18th is the opening window for sales of single game tickets which go even further to ensuring the financial stability of the team. All games including face offs with the Penguins, Capitals and newly created Vegas Golden Knights will open up to the public on Friday.
I would imagine that the divisional games as well as Chicago and Detroit games sell quickly.
