Ryanair expects to transport 157 million passengers by the end of March 2021. That amounts to a growth of 2.6 percent compared to the current year. That is the lowest growth rate in seven years, which is mainly due to the lack of delivery of Boeing 737 MAX devices.

As a result, the growth percentage could even be reduced to 0 percent, says financial director Neil Sorahan on Monday. Since 2014, the number of Ryanair passengers has grown on average by 10 percent per year.

Sorahan also says that the airline "runs no risk" to miss the target of 200 million passengers a year in March 2024.

Ryanair is one of Boeing's largest 737 MAX customers. The airline has ordered 210 of them and hopes to be able to fly 30 of them in the summer of 2020.

The 737 MAX has been on the ground since March for safety reasons. At the end of 2018 and the beginning of 2019, two fatal crashes with the model took place. A total of 346 people died.

Boeing is trying to get the plane approved again, but that has not been successful yet.
