8. Dublin Airport, Ireland ($4,100)
Dublin Airport, one of Ireland’s two airports that provide United States border pre-clearance services, is by far the busiest airport in the nation. Aer Lingus, the flag carrier of Ireland, Stobart Air, and Ryanair, the largest low-cost carrier in Europe, all have their headquarters at this airport. Despite this airport’s size, there are plans for refurbishment and growth that will enable it to provide convention, hotel, and retail space. A private jet owner will have to pay $4,100 to land at this airport until the refurbishment and extension are finished.
