ORD BA to AA connection / check in
I have a connection in ORD between a BA flight and an AA domestic. My BA flight arrives Terminal 5 at about 2pm and the onward domestic is not until about 10pm.
When I arrive at Terminal 5 I assume I need to collect luggage and go through immigration, but then can I go directly to Terminal 3 and check my luggage in for my domestic flight even though it is around five hours before departure?
