Insolvent German airline Air Berlin hopes to complete its sale by September, the group's chief executive said, as government officials fended off accusations of favouring Lufthansa in the bankruptcy process.
"We want to settle the sale in September at the latest, otherwise customers' trust in the airline will vanish," chief executive Thomas Winkelmann told newspaper Bild am Sonntag.
Lufthansa -- which already leases 38 of Air Berlin's 140 planes -- could buy up to 70 aircraft with as many as 3,000 crew for its low-cost subsidiary Eurowings, Bild reported.
"I would welcome Lufthansa taking over larger parts of Air Berlin," Economy Minister Brigitte Zypries told business daily Handelsblatt Monday, while adding that it was up to the airlines to negotiate a deal between themselves.
Other interested airlines cited in media reports include package holiday firm TUI, British low-cost carrier EasyJet and Thomas Cook subsidiary Condor.
Pugnacious Ryanair chief Michael O'Leary claimed last week that Lufthansa has enjoyed an unfair advantage in the scramble for chunks of the business, especially valuable landing slots at major German airports.
Bavarian investor Hans Rudolf Woehrl lent his voice to O'Leary's criticism of a 150-million-euro ($170-million) German government bridging loan to Air Berlin, writing on Facebook that it amounted to state aid for Lufthansa to build a monopoly.
"It's absurd to suggest that the federal government is in bed with Lufthansa," Zypries told Handelsblatt.
Nevertheless, "when it comes to taking over routes, we would have to check whether there is still enough competition," monopoly commission chief Achim Wambach told the business paper Monday.
Both Air Berlin and the federal government said a Friday offer from Woehrl to buy the airline outright and maintain it as an independent carrier was unworkable.
While government officials and business chiefs wrangle, customers remain in the dark -- with even Air Berlin's frequent-flyer programme "suspended until we have achieved clarity about the situation" according to a message posted on its website.
