Self-transfer & Airline change at Guangzhou
Hello,
Flight route: Osaka-Guangzhou-Bangkok
I am flying from Osaka to Guangzhou by Spring Airlines, have a 3-hour long layover at Guangzhou, and then will fly from Guangzhou to Bangkok by AirAsia. I need to perform an airline change in Guangzhou. I will need to go out of the immigration area and check-in with the new airline.
Both my flights are on the same Terminal.
I am an Indian citizen and I know that the 24-hour free transit rule is applicable to my passport.
My question is:
What is the exact procedure to follow after I land at Guangzhou- for taking the free transit permit and move out of the immigration area to the check-in counters?
Where and how should I apply for the transit permit? After landing, should I go towards the exit or towards the international transfers?
Do you think 3 hours is enough for the same, provided I do not have any check-in luggage?
Also, I have no intention of getting out of the airport. I just want to reach the check-in counters.
I am not very clear from what I found in the airline or the airport website. Any answers would be really helpful!
Thanks a lot!
