Translink runs a regular airport service between Belfast International and Europa Bus Centre in Belfast city centre. It is route number 300 and the airport stop is just outside the terminal doors. At the time of writing the fare is currently £7.50 single or £10.50 return (valid for 1 month), but please check Translink's website for the most up-to-date information, timetables,
Local taxi companies are also available and depending on your requirements you may wish to contact them for a quote. Reliable companies include Value Cabs and Fonacab, although a quick search online will give you many more options.
