Hmmm, not really, most flights HKG-EU did great circle pass roughly over or north of Moscow, pretty far outside the direct conflict area (except the MAD/MXP flights). Even flying a little further north would increase the distance far less than the current complicated southern routes. That said, an airline that flies (me) over Russia/Belarus or an airline from those countries, won't get my money. The moment China goes (military) after Taiwan, the same applies for China. That said, I don't have any issues to pay more for my ticket, just to avoid Russia/Belarus.
