Travel Note
If you live closer to Londonderry or Concord (even some parts of southern Maine) Concord Coach lines is a pretty affordable way of getting the bus straight to your airport terminal. (Aer Lingus is terminal C) Round trip tickets are right around $20, and long term (21 day) parking is free in their extended parking lot!
Travel Note
The C & J bus out of Portsmouth or Seabrook is another great option that also takes you directly to your terminal. C & J offers valet parking at both locations for $25 that includes being able to leave your car there for 21 days. The bus ticket is usually only around $25 as well.
Flight
Flights from Boston to Dublin are very reasonably priced, especially booked as far in advance as possible. Chris and Lauren both use Aer Lingus traveling back and forth to visit each other. The staff are amazing, the meals are decent for airplane food, and the entertainment selection is always good (and updating!). *Don't forget to get there 4 hours before take-off, as it's an international trip! (e.x. if your flight is at 9:30 pm, arrive to Boston at 5:30 pm)
Travel Note
Once in Dublin, there are buses that travel from Terminal 1 at the airport directly to Belfast, if that's where your accommodations are. Alternatively, there are buses from Dublin to Newry and then Newry to Newcastle if you're interested in seeing Newcastle first. Feel free to contact us with any questions, or for any suggestions on buses! The buses run frequently and are very affordably priced, tickets are only around 7 pound (~$8.50). Bus tickets are easily booked online on TransLink Ireland, you'll receive an email with a QR code, and present that to the bus driver. When you're finally up North, tickets are normally booked when boarding the bus. A round trip ticket is called a return, and a one-way is a single. You'll receive a printed paper ticket for either of those. Buses run very frequently, and go practically anywhere! Between buses, taxis, and walking (and even the train if you're feeling that journey), you'll not be short of transportation.
