Find a route from Asia to Europe that DOESN'T cross a war zone, they virtually all fly across Pakistan / Afghanistan for a start. And yes I know the baddies in those regions "allegedly" don't have high altitude capable SAMs. According to "current intelligence estimates". Yet.
Not for all of Asia: to/from Hong Kong and points further north it's usually a much northerly route passing north of Moscow.
Now why did KLM and AF decide differently even if they are the same company? Because they have retained separate risk management teams or because their pain level was different, as a results of their routes?
Is it because they're separate carriers owned by the same holding company, similar to BA/IB in IAG?
