Make sure you include extra time to pass through US Border Control if you’re flying to the US! Also Aer Lingus bag drop closes 75 mins before flight departure for long haul so bear that in mind!

Taking the coach bus to Dublin from Castlebar to departures was affordable and easy.

Allow a full 2 hours for check-in and boarding.

The Aer Lingus flight is on smaller airbus plan with single aisle and only 3 bathrooms for big plane. Gets really crowded trying to move around.

Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Delta is a cut above the others in customer service.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

A bit rush for transit. Food and entertainment are not available

So far so good but food and entertainment are not available for this flight

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

Paid $35 and not able to access the internet at all.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

Took off on time and successfully avoided weather that looked to be a problem along the way

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

Noted in last review. Good to know, though air Lingus on European flights does not offer any food or drink, even though we were on the plane for 3 1/2 hours from Naples to Dublin everything you had to purchase even water.

Seats were alarming close to the row in front of you. I didn’t do the measurements online, which I’m sure they’re available, but it seemed much tighter than other planes, but the airplane itself was well maintained and looked fairly new. My only complaint on the staff was that we’re on an international flight. Normally they give you wine with dinner and the flight attendant decided to pull some strict restrictions and wouldn’t give more than one glass of wine per person, and you could not share with your spouse, which seemed ridiculous when we have four people on the plane with us and only one person ordered wine asked for a second one and she said oh absolutely not. It’s only one per person Which on a transcontinental usually is not the case. They’re very attentive on making sure everyone is as comfortable as possible.

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Too much long line at the TSA and Security. Prepare for long walk for baggage claim.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

The boarding process was quite loud and chaotic. The flight attendants kept barking over the PA system about people needing to only stow large items in the overhead bins. During the one and only service, I was hit by the service cart. At the same time, a passenger was returning from the bathroom and the crew definitely saw him but stopped a few seats short of allowing him to sit down before starting service and made him wait a good 10 minutes before passing his seat and allowing him to sit down, after which he had to ask for his snack and beverage or he would have been passed over. Neither flight attendant thanked passengers as they left; in fact, I did not see them again once the plane door was opened.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

The seats in row 31 are terrible and small and uncomfortable. Don't ever sit there. The window seat is so close to the curve of the plane is so annoying. I paid extra for this seat and I hated all 10 hours in it.

Food was terrible , crew were excellent , IFE was dire . Overall comfortable seat and cabin. Nothing special .

If my tv wasn’t broken and I wasn’t in a seat that didn’t allow for sleeping
