No other recent Lufthansa CEO has forced so much deep change on the airline as Christoph Franz. The announcement of his unexpected departure creates uncertainty, drawing into question whether Europe's largest airline group will continue with reform or stagnate.
Franz confirmed last week that he will not extend his contract, set to expire next spring. Instead, he will become executive chairman of the board of Swiss pharmaceutical giant Roche, replacing Franz Humer. Franz has served on Roche's board since 2011.
