See, this is actually a good argument.

Aren't NOTAMs specific per-flight? I've heard the term from two pilots in my life, but I'm not personally familiar with them. I was under the impression that they do not function as standing orders, meaning the specific 2022 incident was, well, specific to that incident. If there's a continuous no-fly rule for all Russian aircraft in effect, that'd have been a much more useful point than calling the one specific event.

And, for the record, I'd love to see the policy regarding Israel's flights in Canadian airspace changed. I just fail to see the hypocrisy in one event 4 years ago under a different government. If there has been a standing no-fly order since, well, that does in fact change things.
