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.

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from Chicago to Ireland is likely to change within 7 days, so travellers 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 from Chicago to Ireland with an airline and back 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 from Chicago to Ireland up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Crew was friendly and seats were comfortable. The connection however there were no free snacks or drinks.

Our flight from Dublin to Coruna did not exist any more. Apparently it was cancelled in February and I was not advised, nor was I offered any flights for rebooking. Happily Aer Lingus found another flight to another city in Spain that was 500 miles from Coruna; I had to pay for a hotel overnight and a revise my rental car that incurred additional costs, and I did not get to Coruna for another 24 hours. I was not at all impressed with Kayak or Chatdeal or Hertz.

OK overall. Flight was delayed Crew on flight was good

Satin first class and absolutely no snacks are offered. Surface was awful.

Late late late. Delayed and arrived an hour late for a 1 hour 45 minute connection. Every time. Poor record for this company. I try to fly any other carrier first.

This was the smoothest flight I've ever taken with any airline, including Aer Lingus. Typically, there are moments when I feel afraid, but from take off (miraculously seamless!) to cruise, to landing this was a perfect flight. Thank you!

Poor. Plane left EWR late hence missed connecting flight in Dublin. No pro active info from flight staff on connection, only when probed a couple of lies on where we would dock, and on lilelyhood catching connecting flight. Lies as they will have known our EWR-DUB would be parked furthest away from the transit spit - lying it would be next to the AMS flight.

The seat area was way too compact. The person in front reclined, and the TV screen was right in my face. There was a metal box secured to the floor in my foot area, further limiting space. Food was OK. The last service was provided too late in the flight, so the crew was rushing at the end. The ticket counter in the Naples airport was extremely slow. The staff on the flight was friendly.

delayed flight stayed whole night at washington Dallas airport at seats , uncomfortable . i am senior citizen , very tired , worst travel.

I heard that the pilots were actually leprechauns, but I was not able to confirm. Can you please provide documentation if this is true?
