Dublin-based aircraft leasing firm Avolon has committed to buy up to 30 of Boeing's next generation 737 passenger jets worth around USD$2.3 billion at list prices.
It is the latest in a series of deals for the revamped version of Boeing's narrow-body 737 as it battles to catch up with European rival Airbus's popular A320neo.
United Airlines is expected to unveil a USD$9 billion order for 100 737 MAX aircraft on Thursday. The airline will not be at the show itself.
Avolon said it had committed to buy 10 737 MAX 8 planes and 5 737 MAX 9s, as well as 10 next generation 737-800s. The deal also includes reconfirmation rights for 5 more 737 MAXs.
Boeing is leading Airbus in deals at a subdued Farnborough Airshow, the aerospace industry's showcase event, where there are signs a faltering global economy is finally catching up with demand for new planes.
