Try to explain why PVG-PEK-SFO ticket is CHEAPER than PEK-SFO ticket. Same airline and even same flight code.
No, I am so silly to fly back to PVG (Shanghai) only to take a PVG-PEK-SFO cheaper ticket.
Anyway, back in SFO yet again. 3rd time this month. The guy at the immigration was puzzled. Me too.
