Many did. And no they can't "just do it". The hijacking was yesterday, the Ryanair flight took off from Pathos today. They can file a flightpath avoiding Belarus. Maybe it would be 100 miles longer rather than 50, adding 15 minutes to the journey, and a few extra dollars to the gas bill. Very poor judgement.
