Air China -Really a Part of the Star Alliance?
I flew ORD-PVG-SZX and return last week. The connection between Shanghai and Shezhen was on Air China. As is sometimes the case with connections outside UA, seats to the connection are not assigned until check in, which is always a source of anxiety. But the situation regarding check in and baggage on a connection from/to UA is rally bad with Air China. On the outbound, after clearing immigration in PVG, I actually had to hand carry my luggage over to the Air China check in counter, even though it had been checked through to SZX at ORD. Then, on the return Air China would not interline the checked luggage, so I had to first check it to PVG, then claim it and recheck it to ORD at UA. If Air China is really part of the Star Alliance, it seems to operate fairly independently with little cooperation with UA.
