PVG international-international connection
I'm wondering how international connections work at the PVG airport in Shanghai. I will be flying ICN-PVG on either China Eastern or China Southern, and will fly PVG-SIN on Singapore Airlines (SQ) on a separate ticket. I arrive into PVG around 8pm and depart a little after midnight.
Can I stay airside or do I have to clear immigration/customs and then check-in again on the onwards flight?
Also, (maybe I should ask on the SQ board) but anyone know if I can check baggage through to SIN?
