I’ve compiled the Attendance records of all games through the end of February. The league remands flat year over year. (Note: that no outdoor games are included in any of this visuals.)
The league got a bump from the Columbus Blue Jackets tear through the league earlier this season as well as the Oilers opening a new bar in Edmonton. Those gains were offset by big drops in Ottawa and Colorado.
Here is the interactive dashboard where you can look at individual teams detailed performance.
