If the same crew took the plane to ATH their FDP would be quite formidable at 15+ hours.
It would be politicians' duty to take action and close Belarus airspace for EU planes. Sadly this is not going to happen as the EU unlike the US can't even be bothered to close airspace where live fighting is going on and leaves it to airlines to decide whether to fly there. This is not really surprising as the EU has decided it doesn't need one aviation safety authority for one level of safety but 27 national authorities torn between flight safety and promotion of aviation interpreting the same rules with wildly varying outcomes.
As pointed out airlines are not really interested as state hijackings don't rate high on the danger scale and re-routings are expensive which hurts even more in meagre times like these.
