Is there any express bus to take from Baiyun Airport to City after Midnight (2am in the morning)

You can take the airport express line 1 to reach Aviation Ticket Office where you can find Southern Airlines Pearl Business Hotel and Baiyun City Hotel.

Hi,
Thanks for the prompt revert, but at that timing are all the express lines still available? I thought I saw from the schedule on the express line which are until certain timing. If the express line is still available at 2.30am in morning, is it only one line is available? And which bus stop should I go to, there are bus stop 1, 2, 3 & 4.
Can the hotels which you have recommended check-in anytime? Do you have some more choices? Thanks.

Of course not, but express line 1 will not stop operating until the arival of the last flight. So you can still catch taht upon your arrival at 02:00 am as Jimmy suggested.

Generally, the hotels in the city are in service for 24h, so it is relatively easy to check in even at dawn. Except the hotel he mentioned, I also know one named Guangdong Baiyun City Hotel, which is next to the local Railway Station, which can be reached by taking the express bus line 1.
