Regardless of influencers etc the fact is regardless of how quickly the initial stages clear up there will be an ongoing risk for a while.

I wonder if BA could do a deal for fifth freedom flights/refueling stops in India (where they've expanded a lot) to serve onward travel to the far east/Oceania. I doubt they could do so in SIN as the local carrier may have ambitions to fill the gap.

The big issue for BA is QR from a codeshare point of view may be most affected due to the proximity of the US/RAF base to DOH.
