Its possible be transported in the morning from Dazhai (Longji) to airport Guilin departure 11:30?

Well, there is no direct long-distance bus that run between Dazhai and Liangjiang Airport. First of all, you need to arrive at the airport at least 2 hours before the departure. I remember that the buses from Dazhai to GL depart at 08:00 and 13:00. It takes nearly 3 hours on the way. Thus the time is not enough. According to this condition, you need to arrive at GL downtown one day in advance.
