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.

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.

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Golf Bags never made it on the flight. Very expensive golf bag and. Clubs,shoes, clothing. Will file a claim against Aer Lingus

Horrible. Garbage airline. Due to the strike we got a replacement plane/crew. I didn't get my exit row seat I paid for. Food was horrible. Plane was hot and didn't have AC vents.

The first leg of my 2 flights were delayed, causing me to miss my second flight and have to stay the whole night in Dublin. Super upset with this experience, and I still need to figure out how to get compensated for this.

Everything went well, but could have used a bit more legroom.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Long unexplained delay, uncomfortable back row, long waits for trash collection.
