The Dubai Air Show opened Sunday in Dubai with Airbus and Boeing announcing some of the biggest deals for aircraft purchases in aviation history as well as the formal introduction of Boeing’s new widebody 777X jet.

With the help of three major Gulf airlines Emirates, Etihad, and Qatar Airways, the total value of deals announced Sunday was $193 billion, a show record. The previous record was $155 billion in 2007. Orders at the last show, which was held in 2011, totaled $63.3 billion.

The three airlines announced orders for 393 new aircraft. Abu Dhabi-based Etihad was the first to sign a deal: 56 new Boeing aircraft, valued at $25.2 billion, including 50 of Boeing’s new 777X planes. It didn’t stop there as it then announced a $26.9 billion deal with Airbus for 87 jets that includes 50 of its forthcoming A350 aircraft

Emirates, which is controlled by the government of Dubai, placed the largest order at the show, a $76 billion deal for 150 Boeing 777X planes but a $23 billion contract for an additional 50 Airbus A380s. With the announcement Emirates will have 101 of the superjumbos on order. It currently operates 39 of them.

Doha-based Qatar Airways ordered 50 of the new 777X planes with a $19 billion order, and Lufthansa became the plane’s fourth launch airline, with an order of 34.

Boeing CEO Jim McNealy said that the $100 billion in orders for the 777X make this “the largest aviation product launch” in history. Boeing also received an order for more than 100 narrow-body jets from flydubai, a budget airline in the region and Etihad also ordered 30 Boeing 787 Dreamliners.
