Ryanair's flight schedules will not be affected by the grounding of the Boeing 737 MAX jet, the airline's chief legal and regulatory officer said today. 

The US yesterday joined countries around the world, including Ireland, in grounding the 737 MAX following a fatal crash in Ethiopia on Sunday.  

Ryanair has ordered 135 737 MAX 200s, a modified version of the MAX 8, and has options on 75 more.

It is due to take delivery of the first in April, two in May, two in June and then 50 more before the 2020 summer season. 

"There is no risk for Ryanair's summer programme," Juliusz Komorek said at a press conference in Warsaw. 

"Our fleet of 450 planes includes a lot of emergency planes, which are located strategically," he said.

He said it was too early to say if Ryanair would try to cancel its order.

Meanwhile, Ryanair said its Ryanair Sun brand will rebrand as Buzz in Autumn of this year and will operate on a Polish Air Operator’s Certificate (AOC).

Ryanair Sun, a standalone business unit of the Ryanair Group, obtained its Polish AOC certificate at the start of 2018 and flew for Polish tour-operators last summer with a fleet of five aircraft.  

Ryanair said the Buzz fleet currently includes 17 aircraft and will grow to 25 aircraft in summer 2019.

Buzz is one of four airlines of the Ryanair Holdings Group, alongside Ryanair DAC, Laudamotion and Ryanair UK.
