Boeing's 737 Max planes have been grounded since March after two deadly crashes.
Similarly, the owner of Lion Air - the Indonesia airline whose Max jet was involved in the first fatal crash in October - vowed to cancel.
On Sunday, Saudi airline flyadeal canceled a $5.9 billion order with Boeing for 737 Max plans and made a deal for 30 Airbus A320neo airplanes.
United States aircraft manufacturer Boeing says deliveries in the first half of 2019 dropped 37 percent year on year following two crashes involving the company's airplanes.
Of those 13 orders, none was for a 737 Max.
Boeing previously got a boost at the Paris Air Show when the parent company of British Airways and Spain's Iberia said it meant to buy another 200 Max planes. Boeing did deliver 24 of an earlier 737 model during the quarter, along with 42 of its 787 Dreamliner.
A more upbeat and expansive Airbus revealed it had delivered in the first half of 2019 315 single-aisle planes, a category which now includes the A220, as well as 17 A330s, 53 A350s and four A380 superjumbos.More news: Netanyahu Warns Iran It Is Within Range Of Israeli Air Strikes

"We remain confident in the 737 MAX's return to service". Analysts expect that to rise sharply.
Plane deliveries are tied to company revenues and closely monitored by Wall Street.
"With its entire modernization effort hinged on the transition to the MAX 8 aircraft, Southwest needed to convince the public and its customers that the aircraft was safe", the lawsuit said.
Delta hopes to utilize its new Airbus aircraft to partially replace older aircraft, such as the Boeing 757.
"We continue to evaluate Boeing's software modification to the MCAS and we are still developing necessary training requirements. on the most recent issue, the FAA's process is created to discover and highlight potential risks", Federal Aviation Administration (FAA) said, adding that it will lift the aircraft's prohibition order when it deems that it is safe to do so.
That's a steep drop from the same time past year, when Boeing reported 277 orders.
The drop-off has accelerated during the year, with the second quarter being worse than the first.
