I have a connection with united and lufthansa is my final flight. Whose baggage policies will be enforced??
Any ideas??
Simple answer:
Whichever airline you are beginning with at each end.
Harder answer:
The Most Significant Carrier (IATA 302 and the DOT regulation)
I would imagine LHR to MAA is less lengthy than SFO-LHR, and hence UA is the MSC.
