Do you think we can make it to our next connecting flight if I bring baggages? from International Terminal to Domestic Terminal How and How Long Does It take? When we land in the international terminal, how and where should I claim my baggage? what other procedures should I do when I reach PVG?
If my first flight delays for 2 hours, do you think I can make it to my next flight after claiming baggage? is it true that all of China eastern airlines flights delay? and how long does it delay usually? Thank you.

How long before the flight should I check in for my domestic flight? Thanks
