Will you make a transfer between two international flights or including a domestic section? In the former situation, you have to wait for the connecting flight in the transit area, no hotel has been set. For the second condition, you could stay one night at the hotel outside the airport terminal, located in walking-distance.

my flight is with the same airline. china southern airline. it only have the 23hrs lay over. and because this the first time i travel not with a direct flight, when i reach the first stop, what are usually the process to go to the other flight. should i go directly to the departure area/gate or do i still need to pass through the departure process. passing through the check in area and security check? thank you for the response.
