Airbus AIR.PA said it expected to finalize the transaction with the 80-year-old Franke in the coming weeks.
After Boeing (BA) shocked the industry with a surprise deal with Emirates, rival Airbus (EADSY) responded Wednesday with a $49.5 billion aircraft order from US investor Indigo Partners at the Dubai Airshow, the largest in Airbus' history. Instead, Indigo has used the negotiating power of its many carriers to buy in bulk.
Airbus' previous biggest-ever sale came in August 2015, when it sold 250 A320neos to Indian budget airline IndiGo, a deal estimated to be worth $26 billion at list prices.
Boeing 737 MAX 10s, a twin-engine, single aisle plane capable of carry 230 passengers, have a list price of $124.7 million.
This year, however, Airbus's share of the order tally had dropped to 35 percent prior to the Dubai show, as a rejuvenated Boeing management made advances in Singapore and elsewhere.
Airbus and Boeing went into the air show with 288 and 605 net orders, respectively.
Budget airlines partly save money by buying large numbers of jets at low prices when manufacturers are eager to fill up their order books, and then generally sticking with one type. But at this stage, it's still a memorandum of understanding, a non-binding agreement that needs to be finalized before it is considered a firm order.
It is also still undergoing negotiations with Middle Eastern airline Emirates - of the biggest early adopters of Airbus' giant A380 - hoping to keep its business onside, despite the company's recent announcement of a 40-plane order for Boeing's rival 787-10 Dreamliner. Airbus has for now declined to comment.
Airbus employees even filled a news conference on Sunday, expecting the A380 sale, instead to find state-owned Emirates making the deal with Boeing in front of Dubai's ruler, Sheikh Mohammed bin Rashid Al Maktoum.
An anticipated order for A380 superjumbos worth $16 billion failed to materialize at the last moment on Sunday, forcing Emirates and Airbus into further talks to finalise a deal.
