Ryanair has said that it expects to cut its summer capacity due to a shortfall in its Boeing aircraft deliveries.
The airline has again revised downwards its summer 2020 schedule based on receiving just 10 MAX aircraft rather than the 20 as previously planned. 60 planes had originally been scheduled for delivery.
As a result, Ryanair cut its expected traffic growth for the year to the end of March 2021 from 157 million passengers to 156 million.
It also said the shortfall in new MAX planes will necessitate the closure of two more bases - Nuremberg and Stockholm Skavst - in March.
"We regret these two further base closures and minor capacity cuts at other bases which are solely due to further delivery delays to our Boeing MAX aircraft," Ryanair DAC CEO Eddie Wilson said.
"We are continuing to work with Boeing, our people, our unions and our affected airports to minimise these capacity cuts and job losses," Mr Wilson added.
Ryanair, one of Boeing's biggest customers, said in November it expects further delay to its Boeing MAX 737 deliveries and may still be without the jets next summer.
The 737 MAX, Boeing's fastest-selling aircraft, was grounded in March after two crashes attributed to anti-stall software in which a total of 346 people died.
US airlines have so far cancelled planned MAX flights until March and a return to service is likely to take longer in Europe.
Boeing took a $4.9 billion charge in the second quarter to cover anticipated compensation for its airline customers' lost business.
Michael O'Leary has previously said MAX compensation could be assessed only once final delivery dates were known.
