Dublin Airport (DUB) is located about 10 km north of the city center and is served by most international airlines. Cheap tickets for flights within Europe are often offered by Aerlingus, Ryanair and some of the other ‘no-frills airlines’. There are different options to get from the airport to the city center, most of the major hotels and DIAS. Taxis are not necessarily the best choice, they are expensive (about 30€ one way) and it is not unusual that the driver doesn’t know the street name or where the destination is exactly located. The Dublin Bus company offers different connections to the city center (no night service!): The Airlink costs 6€ for single ticket (10€ return) and connects the airport with the Busaras (the central bus station for provincial buses located north of the Liffey) via O’Connell Street. The bus no. 746 is a normal bus route which is cheaper but might take a lot more time and is not running very often (from 8am to 8pm about once an hour). An other good alternative is the so-called Aircoach . There are two routes going to the city center and south city serving the major hotels in town. A single ticket costs 7€, the return is 12€. They offer a 24-7-service: once an hour from midnight to 4am and about every 10-20 minutes the rest of the day.
