Mr Mac
I keep reading that various European carriers are starting, or plan to restart services between UK airports and France and Germany, but since as you have pointed out the criteria for being able to travel are quite strict it kind of begs the question what is the point. Flights are going to be largely empty, and yields abysmal. As and when countries begin to loosen the rules, allowing non-essential business travel then it might make some sense, but from what I read on ARD teletext this morning, although there are glimmers of movement in the rules from some countries, mostly in eastern Europe there appears to be no real willingness by France or Germany to row back on cross border traffic at the moment, and the Germans really seem to have ruled that out until early June.
