Online Check-in for Domestic Leg of Intl Itinerary
Travelling LAX-PVG next month. I've requested a sticker upgrade on the ORD-LAX leg of the return. If I don't get it in advance, can I check in online to maximize my chances of getting the upgrade at the gate? I'm guessing the answer is no, but I thought I'd verify with the experts here. Is the answer the same if it were for the outbound LAX-ORD leg? Thanks.
