Am Oneworld Sapphire, flying BA First into PVG, then an 8hr wait (allowing me to pop into Shanghai), then JL Business to HND.
1. Do I need to collect my checked luggage in PVG? (think I read somewhere that PVG don't perform I:I interlining?)
2. If necessary, can I check my luggage in early (like 7 hrs early) at PVG for my onward JL flight?
3. Am paying 15k avios for my JL PVG-HND flight in 767/SS6. Worth it? (7500 avios economy is available)
Thanks!
