Plan would see Lufthansa would take over Air Berlin's long-haul routes
German businessman bids for Air Berlin
The German businessman Alexander Skora is bidding for Air Berlin with unidentified international investors and aims to keep it flying with a limited route network, he said in a statement on Monday.
"I mean routes such as Majorca and other selected destinations," he said.
Under his proposal, Lufthansa would take over Air Berlin's long-haul routes and easyJet other European routes, the statement said.
Air Berlin, Germany's second-largest airline, filed for bankruptcy protection in August after shareholder Etihad Airways withdrew funding following years of losses.
