Thanks for all the info. Given that PVG is not a OW hub and the JL/knowledgeable OW people aren't likely to be there as it's way past their last flight, I'm thinking that maybe I should endure the 8 hours transit in PVG, although it would probably be very painful with the bad lounge and everything. Although, looking at Expertflyer seems like the outbound UL flight has horrendous on time track record with only 23% on time and average 35 min delay.....
