It iwill be an ACMI style lease from Brussels Airlines to EW. With Brussel Airlines crew and Belgium A/C registration but on a German employment contract. From DUS.
Lufthansa want to copy the Brussel Airlines "lowcost" model into the EW
business.
That means the A/C will get a first class and/or business class section on board.
The A340 will fly to north America and the A330's mainly to Asia and the Caribbean. Lufthansa wants to base 40 EW airplanes in DUS.
short and longhaul.
An old school hub system.
They wiant to use ex-AB slots and equipment for this.
So Lufthansa have a hub in FRA and MUC and a Loco hub in DUS.
A monopoly. You have no choice other than to fly a Lufthansa company.
On the 12th of December Lufthansa and easyJet will/might get the Cartell Authority approval of the AB take over. It might not get approved for Lufthansa.
But that probably is why they use their Belgium part of the group for this.
