1) 2 separate tickets
2) 2-hrs. 10-mins connection

But still, on the one ticket, REP-PVG-NRT, all on MU, luggage couldn't be thru checked to NRT.

And there was a later flight on MU from PVG-BKK. However, when I arrived (an hour late) in PVG, i cleared customs & walked from T-2 -> T-1 because my luggage was tagged thru to BKK. I had no idea I had to collect luggage in customs -- which I found out upon arrival at MU desk! So, I traipsed back to T-2, got back into customs, collected luggage, walked back to T-1 and missed the last flight to BKK. This was after already about 20 hours of travel -- I was exhausted.

So, why bother with PVG? NRT transit so much simpler...
