I think that Lufthansa selling bmi or selling any slots to BA at this time is short sighted, by the sounds of it a tactical move to stem losses or avoid down grading of rating of the company.
Lufthansa has an opportunity to build something strong and sustainable at Europe's busiest International hub.
If we look at Cityjet (obviously a much smaller airline), overnight losses were turned into break even and soon to profit as AirFrance combined sales and marketing functions and removed much duplication in the respective head offices.
While these are different times I realise, surely there are synergies to be had and an opportunity to turn Bmi's losses around.
However, if there are discussions on whether BA can buy some slots (assuming BA would be able to buy or want to buy?) could this be a prelude to BA moving to Star?
