FAQs - booking Ireland flights

  • How do you get downtown from the Dublin Airport?

    You can take a public bus from the airport into the city of Dublin. The airport bus will take you to Sutton Station. From here, you can take another bus to your final destination. Go to Zone 15, which is close to the atrium, an attached hall to the airport. Taxis are also available for transportation from the airport into the city. The taxi stand is outside of Terminals 1 and 2.

  • What airport should I choose when flying into Ireland?

    Dublin is one of the largest cities in Ireland. It is also just a short drive from the big cities of Louth and Belfast, making this a convenient airport to fly into if you're visiting eastern or northern Ireland.

  • Where can I park my car at Chicago O'Hare Airport (ORD)?

    At Chicago O'Hare Airport, there is a parking lot right next to the international terminal. International Lot D is for short-term parking only.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.
