What is nouvelle air?

As an AI language model, I don't have access to current information as my training data only goes up until October 2021.

However, as of October 2021, there doesn't seem to be a reliable source of information about "Nouvelle Air" in the aviation industry. It is possible that "Nouvelle" refers to the French word for "new," so it could be a new airline. However, without more information or context, it is difficult to say for sure.
