"Appears" is doing some heavy lifting in my comment, and was there for a reason. If you know of a more representational route I'd appreciate your sharing it.

My previous link was based on a search for London-Singapore air routes. Hrm ... I suppose FlightAware or FlightRadar24 might show this, and yes, it does. BA21 seems to fly over Russia per FlightAware: <https://www.flightaware.com/live/flight/BAW21 https://www.flightaware.com/live/flight/BAW21> SIA308 flies a more southerly route, crossing the Black Sea and Turkey rather than overlying Ukraine, and conspicuously avoiding Afghan airspace: <https://www.flightaware.com/live/flight/SIA308 https://www.flightaware.com/live/flight/SIA308>
