I think the question is which option is safer. Sure, being on one plane close to others is problematic, but it's important to consider the comparative level of safety in the United States and Germany.
For example, in the United States, at least 3,921 people have died (about 12 per million), while in Germany there are 732 (about 9 per million). However, these numbers change daily and are not the best indicator of where we are going. In the same sources, however, you will find these charts:
This implies that the tipping point between exponential growth and saturation is already in the past in Germany (it can, however, return to exponential growth, for example, if people resume their pre-crown habits), but not in the USA USA
A frequently used metric is also hospital beds per capita. Wikipedia lists a higher number for Germany, however ICU beds are less per capita in Germany than in the US. USA Also, I couldn't find reliable data on the fans, which may be another important metric.
