Yes, traveling between Belfast and Dublin Airport is highly efficient in 2026, with several operators providing direct, non-stop coach services. The most prominent service is the Ulsterbus X2 (operated by Translink), which departs from the new Belfast Grand Central Station and runs directly to Dublin Airport Terminal 2 and Terminal 1, typically taking around 1 hour and 50 minutes. Another major player is Dublin Express (partnered with National Express), which offers the 785 service with frequent departures throughout the day and night, featuring amenities like free Wi-Fi and generous luggage allowances. Fares are dynamic but often start as low as £7–£10 when booked in advance online. These buses are a popular alternative to the Enterprise train, as they drop passengers directly at the airport doors, whereas the train requires an additional bus transfer from Dublin’s Connolly Station.
