I know a couple of families (parents and children under 10) who are split up at the moment in different countries and trying to work out how they will get back together.
In both cases they were visiting parents in another country to where they live, and for different reasons, they weren't in a position to be able to just jump on a flight to get back to their families when flights were being cancelled and boarders closed.
One of them is hoping BA will be able to bring them back to their partner and kids who they haven't seen for three weeks.
