(Bloomberg) -- Deutsche Lufthansa AG is making permanent cuts to its fleet and closing a German discount airline to recalibrate its operations for a years-long recovery from coronavirus crisis.

The German flag-carrier plans to take 18 wide-body jets out of service, including six Airbus SE A380 double-deckers that were scheduled for sale. Flights for low-cost carrier Germanwings, a local version of the Eurowings unit, will be discontinued, it said Tuesday.

“It will take months until the global travel restrictions are completely lifted and years until the worldwide demand for air travel returns to pre-crisis levels,” Lufthansa said.

Fleet cutbacks are also coming at the German carrier’s Austrian Airlines and Brussels Airlines subsidiaries.

Like airlines worldwide, Lufthansa is fighting to maintain liquidity amid a sudden stop in revenue. The company is in talks with the governments of Germany, Austria and Switzerland, where it also owns an airline, for state aid.

Lufthansa had about 5.1 billion euros ($5.5 billion) in liquidity, according to a Credit Suisse analysis last month, a sum that would barely cover liabilities if cash refunds on presold tickets were taken into account.

In addition to liabilities for refunds, Lufthansa also has expenditures of around 1 billion euros per month, meaning it will need a sizable injection to weather the storm, according to the Credit Suisse analysis.
