I was looking at flying TXL-LHR in march/april, and noticed Bmi have an extra rotation on the route departing at 9pm aprox, so now 4 daily as opposed to 3 daily. This flight is operated as a bmi flight (BD848) rather than a lufthansa operated by bmi flight.
This is interesting when you followed the VC-union pilot strike recently at LH (which went down after one day, mostly due to very arrogant behaviour of the union leaders, overlooking labour laws in Germany), but this is exactly what they feared: Less and less LH operating into UK, more and more taken over by bmi. Wouldn't even be surprised if BHX-FRA would become partially bmi. BHX-DUS and BHX-MUC are already non-mainline-LH (Cityline and Eurowings), which are mostly outside of the VC-union's influence. Wouldn't mind a modern A319 instead of the aging B737, honestly. Oh, DRS ? Great destination, but no profitable market (tried and failed by BA recently) all demand goes nicely via FRA, plus DRS is too close to SXF (2h drive). FR's Saxony airport also is not so far from DRS.
