Dublin Airport contributed a total of €9.8 billion in Gross Value Added (GVA) to the Irish economy - equivalent to more than 3% of the national economy - a new study has found.
The study of the airport's overall economic impact was undertaken by economic consultants InterVISTAS.
It also found that Dublin Airport supports or facilitates almost 130,000 jobs.
About 21,500 of those jobs are directly related to the airport operation in areas such as airport security, airline operations, ground handling firms, immigration, customs and air traffic control.
InterVISTAS also said that the 57% growth in Dublin Airport's passenger numbers between 2013 and 2018 supported an additional 12,400 jobs during those years.
The study found that Dublin Airport spends an average of €218m a year with more than 1,000 separate Irish suppliers.
It noted that figure relates only to procurement by DAA directly and does not take account of spending by other airport-based companies.
The growth in connectivity has played a key role in Dublin Airport' larger economic impact.
Its connectivity increased by 59% in the five years to the end of 2018, making it the second-fastest growing major airport in Europe in terms of connectivity.
Dublin Airport had 31.5 million passengers in 2018 with services to more than 190 destinations in 42 countries.
"Dublin Airport plays a vital role in the Irish economy, as it is Ireland's main gateway to the world,' said Dublin Airport's Managing Director Vincent Harrison.
"The connectivity that it provides underpins Irish tourism and trade, and also helps enable continued investments in foreign direct investment (FDI) in the Irish economy. One of the airport’s key goals is to grow route choice and frequency for the benefit of the Irish economy," he added.
