10th Nov 2025

Planning a trip to / from Belfast to Dublin Airport? There’s no better feeling than heading away on your holidays, but the practicalities of getting to / from the airport shouldn't be a source of stress. Whether you're taking off on a holiday you've been planning forever or jetting off for business, starting your travels smoothly is key.
This guide will walk you through the best ways to travel from Belfast to Dublin Airport, comparing all the different options so you can choose the one that’s right for you. We’ll cover everything from driving yourself to taking the train or bus, helping you make your journey as simple and hassle-free as possible.

How long does it take to get from Belfast to Dublin Airport?

The time it takes to travel from Belfast to Dublin Airport can vary depending on how you’re choosing to travel. Here’s a quick breakdown of the estimated journey times:

  • By bus (Aircoach): The direct journey takes approximately 1 hour and 50 minutes.
  • By car: Driving typically takes around 2 hours, but this can change significantly depending on traffic.
  • By train: There is no direct train from Belfast to Dublin Airport. So the journey involves a train to Dublin city centre followed by a separate bus to the airport, taking roughly 2 hours and 45 minutes or more in total.

Given the difference in journey times, we reckon our 705X bus service is your best option for getting to Dublin Airport. Not only is it the quickest way to travel, it also saves you money on airport parking and drops you off directly outside of Terminal 1 (Zone 2) and Terminal 2 (Zone 20) - making Aircoach quick, affordable and direct!

Your travel options from Belfast to Dublin Airport

If you’re still not convinced, let's look at the main ways to make the trip in more detail, so you can decide which one fits your needs.

Travelling by car

The main benefit of travelling from Belfast to Dublin Airport by car is the freedom to travel on your own schedule. The drive is about 100 miles / 160km and usually takes around two hours. However, this doesn't account for potential delays, especially during peak traffic times around Dublin. You'll also need to factor in the cost of fuel, tolls, and airport parking, which can add up quickly, particularly for longer trips.

Travelling by train

Taking the train is another option, but it isn't a direct route. You would need to take a train from Belfast's Grand Central Station to Dublin Connolly Station, which takes about 2 hours and 15 minutes. From there, you would need to catch a separate bus to Dublin Airport - which you can do via our 700 / 700X city centre pick up locations. However, this will add another 30-45 minutes to your travel time, plus waiting time which will add up to make your total journey time pretty long, with the added complication of changing services with your luggage in tow and limited services on nights and weekends. Overall, not worth it in our opinion!
