A friend was flying MUC-YYZ-ORD (AC codeshare LH/UA) but at MUC the flight was oversold and she got a DBC cert and was put on a LH nonstop to ORD.
Ticket is AC ticket stock.
Where do you submit it? To AC? to LH? What do you do with the 300EUR voucher?
Also her bag is delayed in MUC still after 2 days. She bought some items in ORD. does she submit the bag compensation in USA or in Europe? She has both mailing address in USA and in Europe.
