Travel decisions

So, as everyone knows, most of Europe is closed to air travel and the ground-based travel options are overflowing trying to compensate. As it happens, my flight is broken into two pieces; Lisbon and Munich. Right now flights to Lisbon are still going, but Lisbon is understandably a zoo since it's one of the few mainland European cities that you can still fly to from the Americas.
So, what to do - take the flight to Lisbon then go through what is sure to be a very unpleasant experience getting from there to Munich? Or just wait it out?
Since I'm in Rio I think I'll be going with the second option. Really, really wish I'd brought my laptop to Brazil with me, though...
