Parallel runway operations at Brisbane Airport are essential to avoid delays to flights in and out of the airport in the future. On-time performance measures the percentage of flights that are considered ‘on-time’, which is early or up to 15 minutes later than its scheduled time. This measure is used for both arrivals and departures.
Delays can be due to a number of reasons, including weather events or network issues both in Brisbane and connecting airports. For example, bad weather in Sydney or Melbourne may cause delays at these airports, which then flow on to Brisbane Airport.
