Teams from the three United States airlines that own B-737 Max jets headed to Boeing's factory in Renton, Washington, to review a software upgrade on Saturday, as USA regulators prepared to receive and review the fixes in the coming weeks.
Wednesday's meeting is a sign that Boeing is nearing completion on a planned software patch required to return the grounded fleet to commercial service, though it will still need approval from regulators.
Last week, Boeing said it was "finalizing its development of a previously-announced software update and pilot training revision that will address the MCAS flight control law's behavior in response to erroneous sensor inputs".
For the grounding of the MAX to be lifted, a process likely to take months, investigators will first have to firmly establish the cause of the crashes, Boeing will have to produce a fix for any design flaws, and air safety regulators around the world will have to approve the fix.
"We ... plan to reach all current and many future MAX operators and their home regulators", Boeing said.
Ari Ashkara, president and CEO of Garuda was quoted by the media as saying: "We have sent the letter to (Kevin) McAllister (president and CEO of Boeing Company) that we are cancelling the 49 units on order".
"Right now we're in wait-and-see mode to see what Boeing comes up with", said Capt. Jason Goldberg, spokesman for the APA, part of a delegation of airline safety experts and pilots set to test the upgrade.
American said the advanced cancellations also allow customers to have additional availability and rebooking options. He declined to provide further comment.

The allegations "paint an ugly picture of lawless conduct and greed ", said Nick Hanna, the USA attorney in Los Angeles . Ms Daniels released a statement on Twitter regarding Mr Avenatti, saying she was "saddened but not shocked" at the news.
Tewolde said both pilots of the doomed Ethiopian Airlines plane had been fully trained "beyond" the requirements of Boeing and the U.S. Federal Aviation Administration.
The company has lost about $28 billion (£21.19 billion) from its market share and the MAX - its best selling plane ever - is now grounded with questions over orders worth more than $500 billion. Southwest has 34 of the jets, United Airlines has 14 and American Airlines has 24.
"We have balanced [cancellations] across our system", said the airline.
Although the causes of the crashes haven't been determined, investigators in the Lion Air disaster have focused on an automated system created to use information from two sensors to help prevent a risky aerodynamic stall.
American Airlines plans to cancel flights well into April because of the Boeing 737 Max grounding.
He added that it was still waiting for Boeing to come up with a software upgrade for the 737 Max.
USA and Ethiopian authorities have said this month's crash of Ethiopian Airlines Flight ET302 near Addis Ababa bore "similarities" to last year's Lion Air crash. It also included some self-guided instruction, the official added.
