Major Boeing customer Ryanair said on Wednesday it was confident the U.S. planemaker would get permission to boost the monthly production rate of its flagship 737 model to 42 in October and then 48 by March or April next year, according to a Reuters report. The Irish airline, Boeing's largest European customer, has had to repeatedly cut growth forecasts due to delays at Boeing, which is working to stabilise production after a mid-air panel blowout on a new 737 MAX in January 2024 exposed widespread production quality and safety problems.
