The LH flights from BHX/MAN are just that, LH. They're not commercial 'BD' flights, just flights for LH operated by BD & on the BD AOC There are several non-commercial 'BD' flights over the next few days to get A/C to where they need to be..
Even though the plane is wet leased to LH surely this is still a commercial BD operation as it is earning money for BMI. I agree the positioning flights to come are non commercial flights.
