The answer to this question depends entirely on where you are flying from. For example from the UK to Germany takes around 1 hour and 15 minutes on average.
For the United States, because it is such a big country it would depend on which part you are flying from. Taking New York as an example the time woule be around 8 hours, but from Houston you would probably need to allow around 10 hours and Washington around 9 hours. There will be variations because of wind direction and speed but in general these times would be a reasonable approximation.
It depends on where in Germany you want to fly to.
