BOS-YUL-MUC
Not sure if this is the right place. I am flying Jazz from BOS-(ACJzz)-YUL-(LH)-MUC-(LH)-BCN. Will my bag be tagged all the way through to BCN or just MUC or just YUL? Where do the Jazz flights from BOS arrive and where does LH depart and what are the immigration formalities? I have googled and searched board but it's difficult to get a conclusive answer. It is an AC ticket if that matters. I've never flown AC or connected in Canada and I just want to make sure I know what to expect before arriving.
