Sydney Airport faced multiple flight cancellations and delays on the morning of 12 September 2026 due to a shortage of air traffic controllers. Airservices Australia implemented Air Traffic Flow Management (ATFM) measures to address roster constraints affecting air traffic staffing.
Airline Delays and Cancellations at Sydney Airport
Qantas reported delays lasting up to 80 minutes along with six flight cancellations before the ground delay program was lifted at 8:15 AM. Virgin Australia experienced six cancellations on Sydney-bound flights and reported delays of up to 50 minutes. Additionally, two flights destined for Melbourne were cancelled following a separate ground delay program still in effect.
Airservices Australia’s Response and Official Statements
An Airservices Australia spokesperson
said that although ATFM measures caused some disruption, most departure delays for domestic and international flights were under 10 minutes during the morning due to demand. “Minimal airborne delays are expected through the morning, and departure delays for domestic and international flights out of Sydney are mostly under 10 minutes, due to demand,” the spokesperson added. The agency is actively recruiting more air traffic controllers and streamlined its system to call on additional staff to reduce future scheduling impacts.
Background: Safety Concerns and Senate Inquiry
The flight disruptions occurred amid heightened scrutiny following six near-miss incidents at Sydney Airport over approximately one month, now under investigation
by the Australian Transport Safety Bureau. Some events raised concerns about controller fatigue, contributing to staffing challenges. On the same day, Airservices Australia CEO Rob Sharp and senior executives prepared to appear before a Senate inquiry examining the reliability and affordability of Australia’s aviation sector, especially for regional communities.
Passengers faced cancellations and delays ranging up to 80 minutes at Sydney Airport on 12 September 2026, disrupting travel plans during the morning peak. Airlines and Airservices Australia worked to restore normal operations promptly after the ground delay programs were lifted.
