On January 13, 2026, an Air Canada flight was scheduled to depart from Auckland, New Zealand, for a long-haul journey to Vancouver, Canada. The flight, designated AC40, took off at approximately 2 PM local time after a brief delay, marking the start of what was intended to be a 12.5-hour flight. However, shortly after takeoff, the crew reported detecting an unusual odour in the cockpit, leading them to declare an emergency just seven minutes into the flight. The aircraft, a Boeing 787, was quickly maneuvered into a holding pattern over the Coromandel Peninsula, circling the area while the pilots assessed the situation and prepared for a potential return to Auckland. In standard operational procedures for such emergencies, the plane circled the Hauraki Gulf, Great Barrier Island, and Waitākere Ranges. This maneuver allowed the aircraft to burn off excess fuel, thereby lowering its weight and contributing to a safer landing. After about an hour in the air, Air Canada flight AC40 landed safely back at Auckland Airport at approximately 4 PM the same day. The precautionary return was executed out of an abundance of caution as the pilots prioritized passenger and crew safety. An Air Canada spokesperson addressed the incident, confirming that despite the unusual smell being detected, the aircraft landed normally and was subsequently taken offline for a thorough inspection by maintenance and technical professionals. The spokesperson also stated that the airline was making arrangements for passengers to be rebooked for their final destinations. Emergency landings due to strange odours are not unique occurrences and are sometimes prompted by various factors, such as mechanical issues or environmental pollutants. This incident reflects the importance of prioritizing safety in the aviation industry. History has demonstrated that unforeseen circumstances during flights can lead to quick and decisive actions, evidenced by a similar event involving a United Airlines flight last month that also had to divert due to a burning smell during its journey. Such incidents remind us how crucial it is for airlines to have established protocols for emergency situations, ensuring that passengers are at the forefront of their operations and safety measures.
