I bought a return YVR to DUB for around $860 with a layover in MUC. I will be travelling without luggage. I want to get off in MUC but still use the return from DUB. YVR/DUB is operated by Lufthansa. DUB/YVR is operated by Air Canada.
If I don't board the connector MUC to DUB, will my return DUB to YVR be cancelled?
