Irish airline Ryanair has shut three bases on Spain's Canary Islands.
The carrier has confirmed its Tenerife, Lanzarote and Gran Canaría bases closed on January 8th.
It said this was due to "the continued late delivery of the Boeing Max aircraft".
It added that a number of Ryanair bases, including some in Spain, will be cut or closed in 2020.
"We have been working hard to minimise the impact on staff across Europe," a statement said.
Local media said more than 200 jobs were cut as a result of the Canaries closures - those of pilots and cabin crew.
Last month, Ryanair said it expected growth to slow further this year due to delays in the delivery of its Boeing 737 MAX aircraft.
Its expected traffic growth was cut from 157 million passengers to 156 million.
The delay also meant the airline would take a maximum of 30 new aircraft, instead of the planned 58, this summer.
The 737 MAX was grounded globally in the wake of the two fatal crashes in October 2018 and March 2019.
Ryanair had previously warned of cuts to services as a result of delays to deliveries of the plane.
It is also set to close two more bases in March: Germany's Nuremberg and Sweden's Stockholm Skavsta.
In a previous statement to staff, the head of Ryanair Michael O'Leary said: "We will need about 600 less pilots and cabin crew for summer 2020".
