Lufthansa chief executive Carsten Sphor said on Tuesday that the German airline would make a bid for Condor with an option to buy Thomas Cook’s remaining airlines, according to Reuters.
However, Sphor said it would unlikely a single buyer could take over all of Thomas Cook’s airlines due to antitrust regulations.
He declined to comment on the offer price for Condor.
Shares in Thomas Cook leapt 10.5% to 23.9p around noon.
Thomas Cook put its airlines business, which also includes British, Scandinavian and Spanish operations, up for sale in February after issuing profit warnings last year.
