Air Canada has agreed to a tentative four-year agreement with the Air Line Pilots Association (ALPA), narrowly averting a potential strike before a deadline of 15 September. The carrier had said that if an agreement was not reached with the association representing more than 5,200 pilots at Air Canada and Air Canada Rouge, either party may issue a three-day strike or lockout notice. "The new agreement recognises the contributions and professionalism of Air Canada's pilot group, while providing a framework for the future growth of the airline," states the carrier in a 15 September statement. Air Canada did not disclose the terms of the new agreement pending a ratification vote by ALPA members, which is “expected to be completed over the next month”. Meanwhile, ALPA states: "If ratified, the [tentative agreement] will generate an approximate additional C$1.9 billion ($1.4 billion) of value for Air Canada pilots over the course of the agreement." "After several consecutive weeks of intense round-the-clock negotiations, progress was made on several key issues including compensation, retirement, and work rules," says Air Canada ALPA master executive council chair, Charlene Hudy. "This agreement, if ratified by the pilot group, would officially put an end to our outdated and stale decade-old, ten-year framework."

Embraer and Boeing have concluded arbitration proceedings that followed Boeing's April 2020 termination of a master transaction agreement, under which the two companies intended to launch a joint venture comprising Embraer's commercial aviation business and a second joint venture to develop new markets for the C-390 Millennium military aircraft and air mobility aircraft. Boeing at that time said it was exercising its rights to terminate the deal "after Embraer did not satisfy the necessary conditions". Embraer in response said that Boeing had "wrongfully terminated" the agreement and "manufactured false claims", and subsequently sought damages against Boeing and commenced arbitration. Brazil-based Embraer notes in a 16 September US Securities and Exchange Commission filing that "pursuant to a collar agreement recently entered into between the parties, Boeing will pay the gross amount of $150 million to Embraer". Boeing says that it is "pleased to have concluded the arbitration process with Embraer". The US airframer adds: "More broadly, we are proud of our more than 90 years of partnership with Brazil and look forward to continuing to contribute to the aerospace industry in Brazil."

United Airlines has signed an agreement with SpaceX to bring Starlink's wi-fi service to its mainline and regional aircraft fleet. The US major expects to add Starlink's service on all its aircraft – more than 1,000 jets – during the next several years. Testing begins early next year, with the first passenger flights expected later that year, says the carrier. It adds that the "high-speed, low-latency" Starlink service will be free. It notes that the passengers will have the connectivity on their seatback screens along with on their personal devices. "Everything you can do on the ground, you'll soon be able to do on board a United aircraft at 35,000 feet, just about anywhere in the world," states United chief executive Scott Kirby. Starlink is operated by Starlink Services, a wholly owned subsidiary of SpaceX, which was founded by billionaire Elon Musk.
