FAQs - booking Ireland flights

  • Do I need a visa to travel to Ireland?

    Citizens of the US and of the Eurozone do not require visas in order to fly to Ireland. Permanent residents of the United States and all other residents plus foreign nationals who desire to visit the country should check with their local embassy or consulate to see if they need to apply for one before they travel.

  • Should I purchase euros before or after I arrive in Ireland?

    All three of the major international airports in Ireland are well equipped to handle currency exchange transactions and there are also plenty of ATMs if needed, so it is really an individual decision. However, many passengers tend to purchase foreign currency after they arrive at their destination.

  • If I wish to visit Donegal, which airport should I use?

    Donegal is the northernmost county in the Republic of Ireland and if you wish to visit, you can use Dublin Airport as the destination for your flight from the US to Ireland since it is the closest of the major airports in the country.

  • Can I get a nonstop flight from the US to Ireland?

    Yes, you can get a direct flight from the US to Ireland, however, the only nonstop flights from the US to Ireland depart from cities along the US East Coast including New York, New Jersey and Philadelphia (PHL).

These stadiums also host significant European matches and championships, making them a popular arena among soccer fans.

  • Are there amenities for pet owners on the USO-IE0 flight route?

The majority of US airports that provide international flights to Ireland, including SLC and SWF Airports, have a pet-friendly policy that permits visitors to enter the airport with their four-legged companions. The basic regulation in most US airports serving flights to Ireland is that all pets must be leashed at all times, with the exception of when they are using the pet relief areas.

  • How can travelers who plan to fly to Ireland on the earliest flight get to SWF Airport?

    Staying at a nearby hotel is the most effective strategy to catch the earliest flight from SWF Airport to Ireland.

  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest Ireland flight deals.
  • If you are planning a flight from the US to Ireland, you will most likely arrive at one of the three major international airports in the Republic of Ireland: Dublin Airport (DUB), which services the eastern counties, Cork Airport (ORK), servicing the southern counties, and Shannon Airport (SNN), serving the western counties.
  • Although Dublin Airport and Cork Airport rank ahead in terms of passenger traffic, Shannon Airport is the most centrally located of the three and, therefore, it allows for greater access to the interior and western counties. It is also an excellent staging point for exploring the Aran Islands off the coast of County Galway.
  • Flying into Dublin Airport puts you in the nation’s capital and allows for exploration of County Wicklow, County Kildare and County Meath, whereas Cork Airport provides excellent access to County Cork, County Kerry and County Limerick.
  • The Heartland of Ireland, which includes the counties of Roscommon, Tullamore, Mullingar and Offaly, lies midway between Dublin Airport to the east and Shannon Airport to the west, so a flight into either one should provide ready access. However, you are more likely to get better public transportation out of the capital city of Dublin.
  • If you’re looking for inexpensive, nonstop flights to Dublin, Ireland, why not consider flying aboard Norwegian Air International from New York Stewart Airport (SWF)? Located about an hour outside of Manhattan in Orange County, it’s a good alternative to the hustle and bustle of Newark Liberty Airport (EWF) and JFK Airport in addition to being only a short train ride away.
  • Travelers with limited mobility can take advantage of a variety of specialized services at the New York Stewart Airport (SWF) when flying to Ireland. Parking facilities at this airport feature areas designated specifically for vehicles with disabled occupants.
  • As travelers wait for their flights from the United States to Ireland, airport lounges are generally regarded as one of the best locations to unwind. Most economy passengers using Salt Lake City International Airport (SLC) to fly from the US to Ireland opt to relax in the Delta Sky Club before they take off.
  • Travelers who plan to go on vacation in Ireland from the US with their kids should consider flying aboard Norwegian Air International from New York Stewart Airport (SWF). This airline serves direct flights from SWF Airport to Dublin Airport (DUB). Use of direct airlines will ensure that you take the shortest time possible from the US to Ireland, which reduces the likelihood of your kids getting weary before reaching their destination.
  • Consider the idea of staying close to DUB Airport if your aircraft from the US is slated to land in Ireland at night. When travelers arrive at DUB late at night, one of the nicest and closest locations to stay is The Maldron Hotel Dublin Airport. Being one of the nearest hotels to DUB, this hotel is just 1.1 kilometers away and is easily accessible by foot for travelers.
  • The majority of travelers who want to take the shortest time possible from the USA to Ireland should consider departing from either New York Stewart Airport (SWF) or Philadelphia International Airport (PHL). These are the major airports in the US that serve as hubs for airlines offering direct flights to Ireland.

The flight was smooth, the crew was great but the plane was quite old

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Okay considering we had weather delays which the Pilot notified us of immediately!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

We departed and landed early which was a nice surprise. The boarding process was slow.

N Everything was perfect from boarding to assistance to baggage in Tampa

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

All good flight was 35 minutes early when arriving in Edinburgh

Flights were on time actually early service was good and crew cheerful

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

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?

The check in process at the front desk felt slow and it was frustrating that we could not check in online. Everything about the actual flight was great, including very kind flight attendants and a nice larger bathroom. Only thing is that it was very cold in the plane!

I flew economy class. Seats were very good and the crew was excellent

I had a great experience. I would definitely use them again

The pre-check (passport control) for all US flights from Dublin airport is brilliant, meaning these flights come into the domestic airport in the US - it was so quick and easy getting to my hotel once we landed. The plane itself was great, staff were lovely and food was fine.

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

One of the best flight experience I have had in along time. Would fly with them again.

Like getting a bus. No great luxury but will get you there

We were delayed and had to circle due to weather and had to divert for fuel. While I understand that you can’t control the weather I would have appreciated knowing that the crew wasn’t going to run out of hours and then having to spend the night in the Raleigh airport.

Messy plane that was falling apart Small screens that didn't work

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

They forced me to check my hand luggage at the gate.

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

Still hasn’t left. Why are you asking how it was?

Flight was good wish there were more snacks options for such a long flight but stewardesses were very pleasant as was flight crew.

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Absolutely horrible. Flight was delayed 4 hours and they had no clue what was going on.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Boarding was quick and efficient. We arrived at our destination early.

I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

I didn't go from Reno to Phoenix I ended up going from Reno to Dallas to Tucson because my flight rebooked because my Amtrak was late I tried notifying you guys I also don't know what you ask me about my flight because you guys didn't book my flight

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

there are no options s for snack besides cookies would ve nice to have a salty option n
