Will my luggage go through if i would like to get down in Shanghai just for few hours?

Will you travel with China Eastern Airlines all the way? If yes, you needn't claim your luggage, and it will delivered to the final destination. If not, you are advised to confirm this issue with the airline companies.

You transfer from International to International, right? Here are the procedures for China Eastern Airlines passengers: Flight Arrival- Confirm onward boarding pass- check in- quarantine- immigration- security check- international concourse- boarding. :)

Hello, This is Olga. Thank you very much for your reply. Yes. it's a code sharing China Eastern Airlines flight Kuala Lumpur - PVG - Saint-Petersburg (Russia). So, i just "leave my luggage thing" to the airlines?! and i can proceed to check out. But then on the check out they will ask where is my luggage... ? i am a bit confused here.

Yes, your luggage will be delivered to the final destination. You needn't claim it at PVG. Upon landing, just proceed to check out. When they ask where your luggage is, you can show them the luggage tag. Don't worry! Have a nice trip! :)

thank you very much, Olivia! :)
