"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.
American Airlines Boeing 737 Max jets sit parked at a facility in Tulsa, Okla., on May 10, 2019.
Airbus reported 389 deliveries for the same period, up 28 percent from the same period in 2018, according to data on its website.
United Airlines now expects to cancel more than 8,000 flights through October because of the grounding of its Boeing 737 Max planes.
For the past four months, the USA aerospace giant best-selling MAX planes have been barred by safety regulators, which is far longer than Boeing and its shareholders expected.
The good news for both companies is that the demand for air travel, and new fuel-efficient planes, is growing.
He described the preliminary order, which gave the 737 MAX a boost at last month's Paris Airshow, as a "great move" by IAG Chief Executive Willie Walsh, even though at this stage the deal is only a letter of intent (LOI).
Indeed, orders for all 737 models including the Max fell by more than half through June, figures released by Boeing on Tuesday show. The aircraft was a Boeing 737 MAX.
According to the suit, the 11 plaintiffs bought Southwest tickets between August 29, 2017, when the airline received its first Boeing 737 Max, and March 13, when the FAA grounded all of the jets. But the IAG order has not been officially booked yet. Just today, Saudi Arabian carrier Flyadeal canceled a $6 billion order for the jet, instead ordered new planes from Airbus. He added that while nobody knew when the MAX would be back in service, he believed this target could slip to end-year.
"While flyadeal's withdrawal is a bit concerning, we would seriously revisit our delivery forecast if a flagship customer like Southwest or Ryanair flipped to Airbus' A320neo or A220 platform", Goode said in a note.
"There are still challenging times ahead once the MAX safely returns to service", he wrote.
Boeing shares fell nearly 2% Monday.
