Not as scheduled. The aircraft was diverted because of unacceptable weather at its primary destination -- https://www.bbc.com/news/articles/cjwl1e6895qo : "The plane was en route to Grozny in Russia but it was diverted due to fog, the airline told the BBC."

Just saying, not excusing a hostile takedown, if that's what happened.

Diversion due to weather is a possibility anticipated by pilots, who normally carry extra fuel to accommodate the possibility of a diversion.

Ironically, because of the advent of drone attacks, a small aircraft like the Embraer 190 is more likely to be mistaken for hostile, compared to a full-size airliner.
