Can I get on the plane at 7:40t 1 in the morning at China Southern Airlines Hotel and take the first airport bus on the 1 line?

The early bus is at half past five! 1 Terminal check-in is half an hour earlier. In other words, you must go to the airport to go through the formalities half an hour before the plane takes off. It is difficult to predict what will happen on the road. But it's no problem to catch the first bus without traffic jam! If you really miss it, you can take the fast track at the K22 counter of HNA!
