How many people travel through Dublin Airport
Between 2002 and 2008, passenger numbers at Dublin Airport grew by 55%, from 15.1 million in 2002 to 23.5 million in 2008. Driven by the growth of the Celtic Tiger economy, business travel, inward tourism and a surge in demand for foreign holidays contributed to the increase in passengers. During this period, the number of routes offered from Dublin Airport grew by almost 50% while the number of airlines actually fell marginally. The busiest route operated at Dublin Airport is the London Heathrow route which is now the 7th busiest route in Europe.
However, when the Celtic Tiger came to an end, so did the growth of passenger numbers with Dublin Airport suffering a 22% fall in passenger numbers from a high of 23.5 million in 2008 to 18.4 million in 2010.

Shannon Airport
On 31 December 2012, Shannon Airport became a publicly owned commercial airport operating under the control of the Shannon Airport Authority plc. In light of the continuous decline of passenger numbers at Shannon Airport since 2007, this move was seen as giving Shannon Airport the power to control its own destiny and removing it from the shadow of Dublin Airport. The airport targets to treble earnings at the airport by 2017. Since the Shannon Airport Authority was setup, five new routes have been opened.
Under the control of the Dublin Airport Authority, Shannon Airport passenger numbers between 2007 and 2012 declined by 70% with each subsequent year from 2007 to 2012 seeing a decline. Part of the reason for the decline was a fall in the number of US troops travelling to and from both Afghanistan and Iraq, however the expiration of the deal between Shannon Airport and Ryanair was a major blow to the airport.
Between 2002 and 2007, passenger numbers at the airport grew significantly from 2.35 million in 2002 to 4.6 million in 2007. Â Passenger numbers during 2013 at the airport are at a level that was last seen almost 20 years ago. 2014 and 2015 have been more positive for Shannon Airport with passenger numbers during 2015 up 21% on 2013.
