Airbus said that it had won a firm order from U.S. leasing company CIT for 10 of its long-haul A330 planes worth $2.3 billion at list prices.
"When a leading leasing company like CIT, places a repeat order for our aircraft, we take that as a strong sign of customer satisfaction," said Airbus chief executive Fabrice Bregier.
Airbus added that Hong Kong-based China Aircraft Leasing Company had committed to buy 36 of its A320 single-aisle planes together worth $3.1 billion.
"This is an important milestone for CALC," said the Chinese group's chief executive Mike Poon.
"We have a long-term commitment to the aviation industry and are very pleased to establish a relationship with Airbus."
The deal includes a commitment to buy eight A321s, the largest member of the A320 family, but none of the manufacturer's future A320neos.
