Sydney Airport Delays: What's The Holdup?

Sydney Kingsford Smith Airport (SYD) is one of the busiest airports in Australia, serving as a hub for various domestic and international airlines. While the airport generally operates efficiently, it has experienced its fair share of delays and disruptions. Several factors, including weather conditions, security incidents, and operational challenges, have contributed to delayed flights at Sydney Airport. In this discussion, we will explore the various reasons for flight delays at Sydney Airport and examine the impact of these delays on travellers and the aviation industry.

Weather conditions

The impact of weather conditions on flight operations is also evident in November 2024, when a major storm caused wet weather and disruptions. Additionally, a spring heatwave in November 2024 saw temperatures soar to 38.2 degrees Celsius in Sydney and eastern NSW, causing discomfort for travellers and staff.

While weather conditions can cause delays, they can also pose safety risks. In June 2024, a Qantas passenger jet was forced to abort its flight due to a bird strike. This incident highlights the importance of considering not just the impact on scheduling but also the potential hazards that adverse weather conditions can create for aircraft and passengers alike.

It is worth noting that weather conditions are not the sole factor influencing delays at Sydney Airport, as various other factors, such as staff shortages, security incidents, and operational issues, also contribute to disruptions. However, when unfavourable weather events occur, they can significantly affect the timely departure and arrival of flights, impacting travellers' plans and experiences.

Staff shortages

Sydney Airport has faced significant challenges due to staff shortages, resulting in long delays and passenger frustration. The impact has been felt across both international and domestic terminals, with passengers facing extensive wait times.

In May 2022, travellers reported waiting for up to two hours to get through security checks, with queues stretching outside the terminal building. This issue was exacerbated by closed security gates, with only a handful of stations open for screening, leading to a bottleneck situation. The situation was further aggravated by the high volume of travellers during the Easter and school holidays, creating a "perfect storm" of delays.

The Qantas CEO, Alan Joyce, initially faced backlash from passengers for blaming them for the delays, claiming they were "not match fit" and needed to be reminded to follow security protocols. However, he later retracted his statement and acknowledged multiple factors contributing to the issue. Sydney Airport advised passengers to arrive at least two hours before domestic flights and three hours before international flights to account for potential delays.

In addition to security staff shortages, Sydney Airport has also faced delays due to a shortage of air traffic controllers. In July 2022, landing restrictions were implemented on multiple days, causing disruptions to flight schedules. While Airservices Australia, the employer of the country's air traffic controllers, denied claims of insufficient staffing, they conceded that absenteeism due to illness had contributed to the delays. The air traffic controller union, Civil Air, emphasised the importance of addressing burnout and promoting long-term training and retention measures to ensure safe and efficient air traffic control services.

Security incidents

Sydney Airport has faced several security incidents that have impacted flight operations and passenger safety. Here are some examples:

On April 27, 2024, a security breach occurred at Sydney International Airport when a man was seen running across an aerobridge. The individual attempted to enter the cargo hold of a flight, but baggage handlers intervened and he was arrested on the tarmac. This incident caused a disruption to flight operations and likely contributed to delays.

In another incident on December 4, 2024, a 27-year-old man allegedly forced open an aerobridge door, boarded a plane, and knocked a security officer unconscious. This breach in security resulted in an investigation and likely impacted the timely departure of flights.

Sydney Airport has also faced security threats that have grounded flights. On October 20, 2024, reports of a major security threat prompted investigations, leading to the grounding of an Air New Zealand flight. Such incidents can cause significant disruptions and delays for passengers and airlines.

To ensure the safety of passengers and staff, Sydney Airport has implemented various security measures. These include regular security updates, the presence of security officers, and the use of security lanes. However, despite these measures, security incidents can still occur, causing delays and affecting the overall travel experience.

It is important for passengers to stay informed about potential delays and security updates by checking the flight information screens within the terminal and staying alert for any announcements or instructions from airport staff. Being proactive and aware can help mitigate the impact of security incidents and delays on their travel plans.

Refueller strike

On August 21, 2024, Sydney Airport refuellers employed by Ampol Aviation announced a 12-hour strike expected to cause major delays. The strike was in protest of Ampol Aviation's refusal to meet their demands regarding pay and secure employment. Over 50 refuellers stood down from shifts across three shifts: the night shift between 1 am and 5 am, the day shift between 7 am and 11 am, and the afternoon shift between 6 pm and 10 pm.

Ampol Aviation services 16 airlines, including Qantas, Virgin, Jetstar, Air New Zealand, Delta, and British Airways. The strike was predicted to impact domestic routes, particularly those between Perth and Darwin, as well as some international flights and routes between Melbourne and Brisbane. Sydney Airport advised passengers travelling on the day of the strike to stay alert for messages from their airlines regarding flight status.

The refuellers had been in negotiations with Ampol Aviation for six months, seeking improvements to leave entitlements, an increase in full-time positions, and a fair wage increase. In the three years prior, refuellers' wages had increased by just 3.5% while the cost of living had risen by 15%. Ampol Aviation claimed that keeping refueller wages low was necessary to maintain long-term contracts with airlines.

The Transport Workers Union (TWU) supported the strike action, stating that the workers had been forced to take action due to Ampol Aviation's refusal to address their reasonable requests. TWU Queensland and NSW State Secretary Richard Olsen emphasised the dedication and professionalism of the refuellers and called for the establishment of a Safe and Secure Skies Commission to ensure fair standards and secure roles for all workers in the aviation industry.

Ampol Aviation expressed disappointment over the proposed industrial action, stating that they had offered a 25.6% remuneration and benefit uplift over the life of the agreement. They also mentioned their willingness to continue negotiations to reach a mutually beneficial resolution.

Runway closures

Sydney Airport has a number of major construction projects occurring close to its runways, as well as routine maintenance work, which can sometimes cause flight delays. One such project, approved by the Australian Government in 2019, involves the construction of two new taxiways, the extension of an existing taxiway, and the addition of six new aircraft parking bays in the airport's southeast sector. Due to the proximity of the worksite to the runways, the use of certain runways will be affected to ensure the safety of workers.

As a result of this project, the east-west runway was temporarily closed for up to 10 weeks from October 2023, and the number of aircraft using the two north-south runways increased. This change in runway usage can cause delays for flights to and from the airport.

In addition to construction projects, Sydney Airport also carries out essential maintenance work on the main north-south runway and associated taxiways. This maintenance work is conducted during the airport's curfew, between 11 pm and 6 am, and only on Friday, Saturday, or Sunday nights to minimise noise impact on nearby residential areas. During these maintenance periods, any overnight freight and other aircraft that would usually operate during these times are redirected to the parallel north-south runway.

While these runway closures and maintenance activities are necessary for the safe and efficient operation of the airport, they can sometimes cause delays for flights. It is important for passengers to stay updated on the status of their flights and be prepared for potential delays when travelling through Sydney Airport.
