Boeing said it has written orders for 259 777X jets at the show that began Sunday with 225 of those ordered by three airlines: Emirate Airline, Etihad Airways and Qatar Airways.
The Wall Street Journal reported Monday that Deutsche Lufthansa ordered the other 34 777X jets, while orders for other models came from discount airline Flydubai.
The value of Boeing's orders was about twice the value of deals written by rival Airbus, a division of the European Aeronautic Defense and Space Company.
The show underscores the shift in the industry toward Middle Eastern carriers that are looking to offer a wide range of options for passengers. The Journal reported that the 777X jets, which carry 350 to 400 passengers, have wider wings and a more powerful engine to facilitate take-offs in extremely hot conditions.
The Dubai airport is on track to become the world's busiest that will eclipse London's Heathrow airport, which is currently the busiest.
Another reminder of the global shift in the industry, Emirates, the largest airline by capacity, signed deals with Boeing and Airbus that came to about $99 billion, although discounts could lower that considerably.
The airline ordered 150 777X planes -- and order valued at $76 billion -- which only puts it further ahead as the owner of the world's largest 777X fleet, the Journal said.
