German Lufthansa Group has finalized its acquisition of Italian airline ITA Airways, closing a long period of uncertainty for Italy's former flagship carrier.

Under the €325-million ($350-million) deal, Lufthansa takes an initial 41 per cent stake in ITA, formerly Alitalia, from the Italian government, gaining full control by 2033 with a total investment of €829-million. The remaining 59 per cent will initially continue to be held by the Italian Treasury.
