Gulf airlines, led by Dubai's Emirates and Abu Dhabi's Etihad, struck plane deals worth almost $150 billion - or more, including options - on the first day of the Dubai Airshow on Sunday.
The buying spree underscored a shift in power in the aviation industry, as oil-rich, fast-growing economies of the Gulf take advantage of their strategic position between East and West to draw more travellers from hubs in Europe and Asia.
While the deals are a big boost to Airbus
Airbus agreed a new deal on Monday with Abu Dhabi's state investment fund Mubadala to expand their partnership "for further composite and metallic aerostructure production in the United Arab Emirates, in addition to procurement of composite raw materials, worth $2.5 billion," Mubadala said.
Reuters reported on Sunday the two parties were close to a deal.
Separately, Boeing said it had also signed a new deal with Mubadala for Abu Dhabi to supply as much as $2.5 billion in advanced composites and machine metals to the U.S. planemaker.
Airbus shares jumped more than 3 percent on Monday following Sunday's slew of orders, which boost its A380 - the world's biggest passenger jet which had been struggling for orders. Boeing's orders boost its new version of the 777 jet.
The hub cities in the Gulf - Dubai, Abu Dhabi and Doha - are spending billions on infrastructure in a bid to attract travellers and diversify their oil-based revenues, at a time when faltering Western economies are struggling to invest.
Mubadala, which has a mandate to develop the emirate's local economy, has sought to play a major role in the production of composite tail sections for passenger jets.
A group representing U.S. airline pilots warned on Saturday the sale of hundreds of planes to Gulf airlines that compete with U.S. carriers would have "serious consequences for the U.S. economy and U.S. airline workers.
Both Airbus and Boeing have already established partnerships with Strata, the composites manufacturing unit of Mubadala Aerospace which produces parts at Al-Ain near Oman.
