The changing hierarchy marks the culmination of mostly organic growth at Lufthansa, aided by the purchase of smaller brands Swiss, Austrian and Brussels and the expansion of discount unit Eurowings, which grew by almost one-quarter last year. Lufthansa also secured a key deal with pilots in 2017 and last year benefited from unexpectedly high demand in first class. Air France-KLM, by contrast, has suffered years of strife as workers resist overhaul plans, leading to successive management shakeups as its French state shareholder balked at sometimes violent labor unrest. The French arm was also affected by air-traffic control strikes last year, as well as the nationwide Yellow Vests anti-government protests.Tom Lavell (Bloomberg)
