This summer, I'm flying from Kunming to Copenhagen through Beijing with a 2.5 hour layover. The problem is the first leg of the trip has a 54% on time rating... And I'm going during the rainy season. There's another flight going through Moscow with an 8.5 hour layover that's on time 94% of the time, but I don't feel very comfortable spending that much time in an airport (I'm only 16 so going into the city for an hour or two, which my parents are adamantly against, isn't really an option). Which flight would you recommend?
