Dubai-based Emirates has placed an order for 150 of Boeing’s new 777 in a $76 billion deal.
Other orders from Etihad Airways, Qatar Airways and Lufthansa for some 109 of the new 777 aircraft, previously codenamed 777X, brought its sales total to $95 billion.
Emirates also ordered 50 Airbus A380 superjumbos in a deal worth $23 billion at the Dubai Air Show.
The airline is already the biggest customer of the A380 and the new deal will bring its total orders for the double-decker aircraft to 140.
The Etihad deal includes 50 A350 XWB and 36 Airbus A320neo family aircraft, together with one A330-200F freighter.
Airline president and chief executive James Hogan said: “Ten years ago this month, we celebrated our inaugural flight from Abu Dhabi using an Airbus A330.
“A decade later, we have grown into one of the world’s leading airlines and the importance of Airbus to our fast-growing operations has never been stronger. We have more than 60 Airbus aircraft in our fleet today, and this latest order is testament to the continued strength of our partnership.
“As one of the first airlines set to receive the much-awaited Airbus A350-1000, we look forward to benefiting from its operational efficiencies and cost savings.”
The aircraft will be used to launch flights to new destinations around the world, add more capacity in established markets and progressively replace existing, less-efficient aircraft, the airline said.
It also provides the unique opportunity to redirect new aircraft orders from Etihad Airways to members of its equity alliance, carriers around the world in which it holds minority shareholdings.
This will enable capacity to be assigned where and when it is most needed, while improving fleet commonality and sharing significant cost synergies, according to Etihad.
Hogan said: “The revenue benefits of our equity alliance, to all the members, have always been clear. What has been less obvious is the opportunity for business synergies which can improve the operating costs of all the partners.
“The flexibility of this deal, and the economies of scale it offers, means all our strategic partners will have the chance to benefit from it.”
The Airbus A350 XWB order includes 40 A350-900 and 10 A350-1000 aircraft, which will be equipped with Rolls-Royce engines. Deliveries will start in 2020.
