Minimum Connection Time and Interlining at ORD
I have an award ticket NRT-ORD-YYZ-GRU, in which the NRT-ORD segment is on NH and ORD-YYZ-GRU on AC. All segments in business class.
The flight ORD-YYZ has changed its departure time and the connection time is now only 1 hour and 20 min, below the MCT at ORD of 1 hour and 30 min.
Will I need to clear immigration and check bags once again or bags go throw from NH to AC?
Is 1 hour and 20 min at ORD, arriving from NRT on NH and connecting to YYZ on AC, feasible? Do I have to change terminals?
