Goodbye Danube, I think

It's a 3 hour 20 minutes flight, so a lot longer than I was expecting. I suppose I've lost track of where we are in Europe, how far east we've travelled. Down below and looking on the small screen overhead showing our location on a map, it would appear we're flying once again over the Danube. We've barely escaped it on this holiday. At least it's been an important feature of all four countries, even if for Romania and Bulgaria it represents their border.
