Domestic aviation accounts for a significant proportion of national travel undertaken by Australians annually, coming second to passenger car usage in terms of billion passenger kilometers covered. Across the busiest domestic routes, 60 thousand trips were flown between Melbourne and Sydney alone during the year ending September 2018 with 885 thousand seats available and carrying 739.7 thousand passengers.
Performance of domestic airlines was good; most flights that were scheduled were flown and many airlines achieved around 70 percent of on time arrivals and departures. Some regional airports had up to four million passenger arrivals and departures over the course of one year.
Between 2011 and 2016, there was a slight upward trend year on year towards increased volume of aviation fuel being consumed, and this is expected to continue until at least 2024 although there has been an increase in the fuel efficiency of newer aircraft.
Internationally, there has generally been an increase in passenger aviation capacity every year. There were approximately 1.5 million international arrivals and international departures during the year ending August 2018.
The aviation industry also has a positive impact on the Australian economy; in New South Wales alone a significant amount of new jobs were created from both international tourism and domestic tourism supported by the aviation sector. International tourism to New South Wales contributed around 7.5 million Australian dollars to the economy, and domestic visitors to Queensland also contributed around 3.3 million Australian dollars. A little under 100 million international tourist visitor nights to New South Wales were supported by the aviation sector, and these visitors spent around nine billion Australian dollars during the same year.
Customer satisfaction with international airlines was high during 2018, with most who chose to fly happy with their experience. Satisfaction with domestic airlines was also of a high level during the same year for both leisure and business travelers.
