EasyJet has bid for parts of Air Berlin's shorthaul business, joining Lufthansa and others in pursuit of the bankrupt airline's assets.
The airline has "submitted a proposal to the overseers of Air Berlin's insolvency to acquire parts of its short-haul business", easyJet said.
"The proposal is consistent with easyJet's focused, city-based strategy in Germany. However, given a number of uncertainties associated with Air Berlin, there is no certainty at this stage that any transaction will proceed."
Shares in the airline have risen by a fifth this year and are trading at £12.13.
