FAQs for booking flights from St. Louis to Dublin

  • How can I make my flight to Dublin more sustainable?

    It starts by booking a flight with fewer stops, because the fewer stops there are on the trip, the lower carbon emissions since you’ll be traveling a shorter distance. You should also opt for public transit to and from the airport to reduce your carbon emissions. Lastly, choose your airline carefully. American Airlines and KLM both have a good sustainability record with the use of sustainable aviation fuel and more fuel-efficient aircraft for their flights.

  • What transfer options are available from Dublin Airport to my hotel in Central Dublin?

    There are only two options available for transfer from Dublin Airport to your hotel. You can either take a taxi or use the bus service. Taxi is the most convenient since they have more room for luggage and will drop you at any destination in the city, making it easier for you to get to your hotel without much hassle. The bus is cheaper, but takes a lot longer than the taxi and will drop you at the station in the city center - meaning you will need to get another bus to your hotel.

  • What are the layover options for this route?

    There are multiple layover options for this route, but the choice of layover boils down to the airline you’re flying with. It is therefore up to you to choose the airline you’re booking with carefully if you want to have your layover in a particular city or country. For instance, when flying with American Airlines, you are most likely to have your layover in Charlotte, since that is one of their major hubs. The same applies to Delta and United with Atlanta and Chicago, respectively.

  • Which travel documents will I need to fly to Dublin?

    The only mandatory requirement for you to be allowed into Dublin is your passport, which should be valid for the whole duration of your stay. A visa will not be required, provided you’re in the country for tourism and don’t intend on staying longer than 90 days. If that’s not the case, then you will need to visit the Irish Embassy for further assistance. It is also worth mentioning that the country has currency restrictions for entry and exit, which are limited to 10,000 Euros or the equivalent amount in US Dollars.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

No problems with flight. Even though I had a short layover in DFW, I was still able to easily make my connection.

American Airlines continues to price it can provide the least comfortable passenger experience in the air. This legacy carrier rivals the budgets for both terrible seats and inadequate amenities. I am a 5’7” woman who is not wider than a coach seat (even on these narrow bodied aircraft). My 3.5 hour flight was terribly uncomfortable because the leg room is inadequate (my knees hit the seat on front of me even when it was not reclined); the seat barely reclines; and the foam padding is worn thin to the extent one can feel the metal supports of the seat. Add to this the fact that the aisle is super narrow, so that the drink cart literally scrapes the arm rest of the aisle seat. It’s basically torture.

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Plane took off without me, my stepdad and a dozen other passengers. It went from an hour delay to boarding in 15 montures without notifying anyone. Names were not called overhead. Now I’m missing a day of work and stuck in Charolette overnight paying for a hotel and Ubers out of pocket

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

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.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

I’m hoping for WiFi included. Everything else was very good

Seats, comfort level ugh. Crew was not attentive, only to coach

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

it would good to have at least something to drink...

Everything was great, except the food, which could have been flavorful.

Took too long to tak off but besides that it was good

I liked that the seat belt fit so I did not have to ask for an extension.

Seating was very tight and not comfortable. Would rather pay extra to get more leg room. Overall, the flight was not as nice as expected. It’s comparable to flying Spirit Airlines or Frontier airlines in America. Even as a budget airlines, Iberia should at least serve water or light snacks, especially for international legs, no matter how short the flights are. We were flying from London, Heathrow to Madrid Spain on a 2-hour flight without offering water, unless you want to pay for the water.

It was great to check carryon luggage at no charge when there was no room for ours. A hidden benefit of having low-tier tickets. Also great to stay off plane as long as possible. Airline gave us seats we wanted on this last leg, again at no charge.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

The late departure Of two hours waitresses, immature, and gossiping

Crowded plane but it flew on time and had friendly staff

We had a good flight, service was good and lots of leg room. Service was good and the staff were friendly.

The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

It was upsetting that the flights were canceled but that was due to weather. I did not receive any vouchers for food or a hotel stay when I was forced to spend the night in Montreal. I was also upset when my seat was changed many times.. The plane seemed old with a non-functioning screen and loose side pockets.. All in all in need of updating. On the positive side, the staff in areas was friendly and helpful.

Lost my bag. My first ever flight with them that they forced me to gate check my bag on, due to them having a 30 year old plane with small carry on bins, and they lost my bag. Never again.

United force you to download their App to do the check-in.
