I am planning to go to zhangjiajie before joining Yangtze river tour from Chongqing. I see that there is a direct flight from Zhangjiajie to Chongqing by sichuan airline (I think). Does anyone know how reliable the flight is, i.e. it gets cancelled often? Because there is only one flight per day at night, and if I miss that, I will miss the river tour.

Thanks a lot
