My trip was safe and comfortable.  I even had an empty seat beside me on both flights.  The only hiccup was in Frankfurt.  Someone flew an unauthorized drone over the airport.  That completely shut things down for a while, but thankfully my flight was only delayed a few hours.  Others were cancelled.  I did get settled in early enough to be able to talk to some folks and finalize study plans for the week.  All in all, it was a good day.
