Which airlines can't check in at the transfer counter?

China Southern Airlines, China Eastern Airlines and other airlines are not allowed to check in at the transit counter. Take China Southern Airlines as an example. Passengers who transfer from international to domestic can enjoy Li Tongcheng's hands-free service if they have already obtained boarding passes and luggage tags for their connecting flights. Please contact the transit staff to "reconfirm the checked baggage" after going through the immigration formalities. So you can't.
