Low-fare airline Ryanair confirmed today it would be buying around £10 billion-worth of new planes in a move that will create more than 3,000 jobs.
The no-frills Irish carrier said it would be taking 175 of Boeing's new 737-800 aircraft, which will be delivered over the period up to 2019.
First announced as a commitment in March, the now-firm order was finalised at the Paris Air Show today.
The new planes will allow Ryanair to grow its fleet to more than 400 aircraft, serving more than 100 million passengers a year across Europe by 2019.
Ryanair chief executive Michael O'Leary said: "We are pleased to finalise this firm order, creating over 3,000 new jobs for pilots, cabin crew and engineers.
"These 175 new airplanes will enable us to lower costs and airfares even further."
Boeing commercial airplanes president and chief executive Ray Conner said: "I could not be more proud to see the partnership between Ryanair and the Boeing Company extended for the years to come."
Meanwhile, Rolls-Royce announced that it has won an order worth around £500 million from SriLankan (correct) Airlines for Trent XWB engines to power four A350-900 aircraft and for Trent 700 engines to power six A330-300 aircraft.
