Certainly a good decision to choose Swiss International for the trip to Berlin. The airline’s service is outstanding, its punctuality notorious, and its prices (sometimes) not much higher than what its rivals charge. Besides, you get a piece of Swiss chocolate on each flight.
Here is a bunch of pictures I took on my way back to Zurich:

Your area of the world is very beautiful. I’ve been there a few times. Austria, Northern Italy down to Rome, Greece. All my favorites.
