The ten teams played two double rounds of 18 games each. This was followed by a single round (nine games) and the best eight teams determined the Swiss champions in playoff style. Quarter-finals , semi-finals and the final were each played according to the Best of Seven mode .
The last two teams determined in the play-outs (in the Best of Seven mode) the team that had to play against the champions of National League B to stay relegated.
In the quarter-finals, only EV Zug had serious problems with their opponent, the Kloten Flyers. Three of the seven games in the series were only decided in extra time.
After the end of the season, the league management decided to add two teams to the NLA. Therefore, the two finalists of the National League B , the EHC Chur and the HC La Chaux-de-Fonds , received a promotion right, which they exercised.
