Q: I bought a United Business Class ticket round trip from TPE - EWR - TPE. However, on the return trip I wanted to go to PVG (so it's EWR-TPE-PVG). If I buy a separate ticket now, with another Star-Alliance airline (EVA), Business Class, would I be able to check the luggage all the way from EWR to PVG from EWR? Also, I will most likely be taking 3 luggage at 32kg each (United elite member), will that work?
Thank you.
