However, many passengers tend to purchase foreign currency after they arrive at their destination.

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

  • 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 agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

Everything was great. The only issue is unfixable. Seats are too small. 😁🤪

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

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

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?

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.

Boarding was fast, easy, and we landed early. The entertainment system was very buggy and kept resetting throughout the flight.

Not having an assigned seat until boarding and then having to check my bag.

Flight emergency landed in Chicago due to “Odor” in back of plane . Had to buy ANOTHER TICKET to get to Boston cash out of my own pocket . Then they would notchange my return flight time without a 400. Charge!!!! Insulting.

I purchased ticket so our daughter ( a minor) can sit next to her mother. No help at gate after kayak insisted that this could be done. She ended sitting by herself

Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

we were an hour delayed after boarding and given no reason. Headsets cost money. Also there were openrows with no one setting in them but we were told we were not allowed to swtich.

Crew was very friendly. Did not like being jammed in the back middle seat. Don’t understand why I can not select an aisle for free based on first come first serve. Also first time I’ve been on a flight which attempted land then circled Detroit airport multiple times.

Terrible. There was a lot of misleading information regarding ticketing, seat upgrades, & boarding group. I also expect my seat will recline. I have back problems & it is very painful for me of the seat doesn’t recline. In addition, when I choose a fare that allows me a carry-on bag, I expect to be able to carry it on. Not be forced to check it. Thos happened on my flight to MCO & back to Boston. Not sure I will ever fly JetBlue again. Further I bought the ticket through hat deal. I will NEVER do that again. They were incapable of providing an accurate record locator # for either leg of the trip. I had to call them before each flight with me VERY stressed about whether I would actually be able to get on my flight. Who does that? Who books flight & then FAILS to give an accurate record locator? Twice!

The flight was delayed 4 hours and the JetBlue people at the counter kept lying to us and telling us it was due to weather however all other flights were going in and out of NY and FL. Then they lied that the plane had to stop to refuel. Then they lied and said the plane needed a tire change. JetBlue is the worst. Then they gave a lot of people meal vouchers however I didn’t know they did that and they didn’t offer anything to me.

My experience with Jet Blue was wonderful. My experience with Kayak sucked and will never use again.

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

On time departure and early arrival. Flight attendant very nice.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

The staff was nice. I appreciated that I was able to take an earlier flight, even though it was last minute. The boarding process felt rather chaotic.
