> They don't have night flights in Europe? Only very few. Part of it is because of night time flight restrictions at any airport near a population center (which are generally the airports that could support flights at odd hours). For example, Heathrow is severely restricted between 23:30 and 6:00. Frankfurt is restricted between 23:00 and 5:00. The other part of it is that the distances involve are relatively short. London to Paris is 1.5h. London to Berlin 2h. Even London to Moscow is less than 4.5h. It’s almost impossible to have an actual overnight journey like you can have flying from New York to San Francisco.
