MSPEconomist, we're flying from London to Zagreb and later from Dubrovnik to Prague. I've never been to Eastern Europe. I did have a Russian trip cancelled this spring.

Most of my travel is to Europe, but I fly to to Asia (Singapore, KL, HKG are typical for work but was in Vietnam, Thailand, Cambodia on a recent holiday), South America (Bogota and Santiago coming up), and North America (NY, SF, Houston, DC, Toronto, Calgary and Mexico City for work and sometimes Calgary, Denver and Akumal/Tulum or Baja California Sur for holiday). I assume airlines will avoid places like Ukraine and Mali pretty assiduously at this point.
