In 2014, Dublin Airport was the 18th busiest airport in Europe, serving over 21 million passengers. By 2016 this increased to 27.9 million passengers passing through the airport, establishing an all-time record supported by growth in both short- and long-haul networks. In 2015 and 2016, transatlantic traffic grew, with 158 summer flights a week to North America, making it the sixth largest European hub for that route over the year. Transatlantic traffic was also the fastest-growing segment of the market for the airport in 2016, in which a 16% increase from 2015 brought the yearly number of passengers travelling between Dublin and North America to 2.9 million.
