Southwest & United Airlines Won’t Accept New Boeing 737 MAX Aircraft With Affected Software

Southwest Airlines and United Airlines have both announced they will not accept delivery of any newly manufactured Boeing 737 MAX aircraft containing the recently identified problematic software. This decision follows an ongoing investigation by the Federal Aviation Administration (FAA) into a specific Vertical Navigation (VNAV) glitch within the aircraft's flight control system. The potential issue poses a threat to the continued delivery schedule for these planes, which has already caused significant disruption across the airline industry. Both carriers emphasized their commitment to passenger safety and operational reliability as key drivers behind this precautionary stance. FAA officials are currently working diligently to determine the full scope of the problem and implement corrective measures before allowing further deliveries.
