Disruptions to flights in and out of Hong Kong are set to worsen on Monday after protesters coordinated strikes to bring the city to a standstill. After dozens of morning cancellations, airport authorities said they’ll start rescheduling flights at 12 p.m. local time and reduce arrivals and departures. Demonstrators targeted key transport links and the airport’s high-speed rail service was suspended because of obstructions on trains and platforms. At a press briefing on Monday, Hong Kong Chief Executive Carrie Lam condemned protesters for pushing Hong Kong to the verge of a "very dangerous situation."

A planned strike by workers at Heathrow airport over low pay planned for Monday has been called off with hours to go to allow for further talks in the dispute. Unite, the union, said talks with senior directors from Heathrow would continue on Monday to avert a second day of planned strike action on Tuesday. A Heathrow spokesperson said Sunday that it remained “hopeful that we can find a resolution and stop this disruptive and unnecessary threat of strike action”. “Airlines may choose to reinstate impacted flights. We regret that passengers have been inconvenienced by this and urge them to contact their airline for up-to-date information on the status of their service,” the spokesperson added. Britain’s busiest airport had already cancelled 177 departing flights over the two-day period as a precaution in advance of the planned action after Unite overwhelmingly rejected a pay offer on Friday. Last-ditch talks aimed at averting the 48-hour walkout of around 2,500 staff — including security officers, firefighters and engineers — had gone on all weekend. Passengers had been waiting on Sunday for confirmation from airlines which flights had been cancelled. Heathrow typically has about 1,300 flights arriving and departing every day, carrying 220,000 passengers. Heathrow said it would remain open during a strike at what is one of the busiest travelling periods in the year but warned that security lines will probably be longer than usual.<br/>
Boeing plans further changes to the software architecture of the 737 MAX flight-control system to address a flaw discovered after a test in June, two people briefed on the matter said late Thursday. The redesign, first reported by the Seattle Times, involves using and receiving input from both flight control computers rather than one. The move comes in response to an effort to address a problem discovered in June during a FAA simulator test. This is on top of earlier announced changes to take input from both angle-of-attack sensors in the MCAS anti-stall system linked to two deadly crashes that led to a global grounding of the plane. Boeing still hopes to complete the software redesign by the end of September to submit to the FAA for approval, the sources said. For decades, 737 models have used only one of the flight control computers for each flight, with the system switching to the other computer on the following flight, according to people familiar with the plane’s design. The FAA said in June that it had identified a new risk that would need to be addressed before the plane could be ungrounded. Under a scenario where a specific fault in a microprocessor caused an uncommanded movement of the plane’s horizontal tail, it took pilots too long to recognize a loss of control known as runaway stabilizer, a Boeing official said at the time. <br/>
