Flight from Chicago O'Hare Airport to Dublin

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. If you're visiting southern Ireland, you might want to fly into Cork Airport, which is a short drive from the cities of Cork and Waterford. Shannon Airport is within close proximity of Munster.

  • Are there car rental companies at any of the airports?

    There are numerous car rental agencies at the Dublin Airport. The offices are outside of Terminal 2. At Cork Airport, the car rental agencies are located in the arrival hall. If you've flown into Shannon Airport, you can also rent a car at the airport. Again, you'll find the offices for car rental services in its arrival hall.

  • 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. If you need long-term parking, you'll probably want to park in one of the economy lots. These are off-site, and a shuttle will take you to the airport after parking your car.

  • How does KAYAK find such low prices on flights from Chicago to Ireland?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from Chicago to Ireland.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from Chicago to Ireland?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight to Ireland from Chicago is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from Chicago to Ireland?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly to Ireland with an airline and back to Chicago with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from Chicago to Ireland?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying to Ireland from Chicago up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

Nothing beats ANA customer service on my opinion. Maybe because of their Japanese culture (and food). Arigatō

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Flight delayed for 2 hours due to a part. The plane sat waiting for boarding for a long time and during final preflight inspection the issue was found. Why not do the preflight inspection sooner if you know the plane is being used?

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.
