Here's how the 18 orders for Boeing's 787-9 break down:
MG Aviation Ltd., part of New York-based Jordache Enterprises, which operates Arkia Israeli Airlines, ordered two of the new planes Wednesday.
CIT Aerospace, a division of New Jersey-based CIT Group Inc., ordered 10 Tuesday.
Ireland-based Avolon, a leasing company, ordered six 787-9s on Monday.
At current list prices, the three deals are valued at about $4.5 billion, according to Boeing. Customers often negotiate discounts.
The planemaker also landed orders or commitments for its 737 and 777 at Farnborough. The show opens to the public Saturday and ends Sunday. It was opened to the industry on Monday.
Boeing Co. landed orders and commitments for 201 aircraft valued at $40.2 billion during the Farnborough International Airshow this week, but not one of them was for the 787-8 Dreamliner that it assembles in North Charleston.
With the aerospace giant at the U.K. aviation expo showing off its slightly larger 787-9, the focus among buyers has shifted away from its smaller sibling.
"I don't think we'll be seeing many more orders for the 787-8," said aviation analyst Richard Aboulafia with The Teal Group near Washington, D.C. "In fact, we may see order book shrinkage as customers convert to the larger Dash-9 and Dash-10 variants."
Boeing plans to begin production on its 787-10 model, the largest in the fleet, but it has not decided on the assembly site yet. The first 787-10 won't be delivered until 2018.
The Dash 9 is 20 feet longer and carries 40 more passengers than the original 787-8.
This fall, the airplane manufacturer has said it will begin assembling the larger model in North Charleston, where parts for the stretch version are made now and flown to Everett, Wash., for final assembly.
Aboulafia said the 787-8 "may stay alive in small numbers, but Charleston will likely move on to the larger variants."
Since it was first announced in 2004, the 787 has received more than 1,000 orders from 60 customers worldwide. Many of those deals are for 787-8s.
But "the 787-9 is becoming the preferred option," said aviation analyst Scott Hamilton of Leeham Co. in Washington state.
Boeing picked up orders for 18 Dash 9s during the airshow.
The company made the longer jet one of its main attractions at Farnborough, one of the marquee events for the global aviation industry. Boeing recently delivered its first completed 787-9 to Air New Zealand, and the company rolled out its own 787-9 at the show.
Boeing also is firming up about $10 billion in orders this week for 111 737 MAX 8s and MAX 9s, deals that will resonate in South Carolina. The company is building a plant in North Charleston to make engine inlet components for that new variant of the popular jetliner. Production at the Palmetto Commerce Park site begins next year.
The 737 MAX has surpassed 2,100 orders from 42 customers worldwide and is the fastest-selling plane in Boeing history. First deliveries are set for 2017. The jet will be made in Renton, Wash.
The 737 MAX line is Boeing's answer to rival Airbus' A320neo and A321neo.
