Although much speculated, the new BM flights ex-MUC aren't yet carrying LH codeshares.
The BM fare classes look aligned with LH's, but the flights are still only bookable through BM, and BRN/LGG don't appear as destination options on LH's website.
I wonder if there's going to be a 'prove yourself' period, as BRS-MUC/FRA were before they became codeshares, and if that's intentional or just a reflection of process times within LH?
