Ryanair is closing its base at Frankfurt Hahn airport after German pilots voted to reject pay cuts, reports the BBC.
The airlines said in a memo to pilots that its bases at Berlin Tegel and Dusseldorf airports were also at risk of closure by the end of the summer.
Airlines around the world are struggling because of travel restrictions amid the pandemic.
Ryanair’s UK pilots and cabin crew recently voted to accept pay cuts to reduce job losses.
The BBC reported that the Ryanair memo to German pilots said: “We must move on with alternative measures to deliver savings, which regrettably will mean base closures and dismissals.”
Ryanair announced in May it was set to cut 3,000 jobs across Europe.
However, earlier this month, the company revealed that it had cut a deal with the Unite union so that UK cabin crew jobs would be safeguarded.
German airline union Vereinigung Cockpit said fewer than half of pilots were in favour of the pay deal, added the BBC.
