Ryanair has reduced its forecasted traffic growth following delays in the production of Boeing’s 737 Max aircraft.

The aircraft is currently grounded after two crashes, in Ethiopia and Indonesia, which killed a total of 346 people.

Boeing has said it is targeting a January return to commercial service for the aircraft.

Ryanair today said it has revised down its summer 2020 flying programme from 157 million passengers to 156 million.

Comment: When will Boeing’s 737 Max fly and will passengers want to board?

The budget carrier said the decision was based on it receiving 10 B737 Max aircraft, half of the 20 it had previously planned.

Two Ryanair bases will be closed as a result of the shortfall in aircraft delivery – Nuremburg in Germany and Stockholm Skavsta in Sweden.

Summer capacity will also be reduced in “a number of existing bases” and Ryanair said it was in discussions with unions and airports to finalise reductions.

Ryanair DAC chief executive Eddie Wilson said: “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.

“We are continuing to work with Boeing, our people, our unions and our affected airports to minimise these capacity cuts and job losses”.
