How lovely to hear that you will be over with us for a few hours next September!
It is possible to make it into Dublin for an hour or two to break up your layover. Probably best to get a taxi from outside of the arrivals as this will be the quickest and most direct. It takes about 30-45 minutes depending on traffic so you will need to take this into account for both journeys there and back.
There are shuttle services from the airport to the city as well. Aircoach
would be the best as there are services every half hour and it runs directly to the city. Dublin Airport
website has some additional information that may be of help regarding travel and also luggage storage
if you have to collect your bags between flights, and also the lounges
has plenty to see and do, but you can just take a walk around the streets and enjoy the experience of just being here. Grab a coffee or something to eat and that all-important souvenir! ☘️
Hopefully, this helps with your decisions, we hope your flights are enjoyable and on time! 💚
