Expect a bad cushion to sit on so maybe buy something to sit on. Bring food because although you get food it’s not that good. Hopefully you’re not delayed because no one will tell you why and you won’t know until the day of

If continuing from LAX on SkyWest, be prepared for a long walk followed by a bus transfer, and get your necessities before you leave the main terminal areas.
JimFlew with Aer Lingus-Mar 2026
The A330 is very loud in the back; better to book a forward seat.

Are Ling’s was great, and boards from the back of the plane, which made boarding way less chaotic and much quicker.

The required privilege for business class while boarding is not given. Food is average. The seats in business class are bad, worn out and dirty

As always, it’s a pleasure to travel with KLM. It is one of my favorite airlines.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

Boarding in NCL is really bad. I'm sure part of that is a directive from the airport that KLM can't change but part of that is due to KLM policy. NCL doesn't announce the gate of departure until 30 minutes before departure. However, when you arrive at the gate area, the gate agents file everyone into one long line and everyone boards from one line at one time. This line can stretch for 200m...easily. There is a separate line for groups 1 and 2 but you don't know it until you get to the gate area and agents don't announce/advertise it. Everyone else is grouped into one line. Are you in group 3? Doesn't matter...you board with group 5. Traveling with a child? Tough luck...you're stuck at the end of the line and board last. The last part is very annoying because none of the gates at NCL (with the exception of 1 used by Emirates) has a jetway. To board, you must leave the gate area, walk downstairs, walk onto the tarmac and walk up stairs to board the plane. Highly challenging if you're traveling with small children. That boarding process begs for a concession to allow people with children to board first because they will need extra time. But there is no such policy. Just a really horrible boarding experience all around.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

They promise free wi-fi prior to boarding and then once on board you are informed you have to purchase wifi even after being a mileagePlus member.

Italian airport boarding is always funny. But to not be able to load my luggage with over 1 hour layover is ridiculous

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Very poor the plane itself was really old, slight smell that couldn’t be named. I didn’t even get a boarding pass UNTIL AFTER clearing security! Even then, they said when I get to my connected flight I’ll get my 2nd boarding pass there! A bit ridiculous!

Wifi wasn't working on one of the UA flights after boarding.

If other people in flight, followed instructions and were much cleaner.

If there is an hour delay, and only one announcement is made regarding why, “a dirty plane” and “we are waiting for the Captain to board”and the screen keeps stating “on time” , and 100 people risk missing connections- who are then told to rent cars, run fast, or get a hotel room… well, that’s poorly managed by a team with no real training. Communicate more and better.

The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.

Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly

I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

Excellent cabin crew. They helped a number of passengers with mobility challenges and a mother with a 3 year old and an infant. Better than most other airlines by far. Well done Eduardo!

Good, I slept the entire flight so I cannot add many inflight details

Internet didn’t work more than 30 seconds at a time. Stared at my seat for most of the flight.

We had a connection flight in Toronto and the checked bags didn’t arrive to the baggage claim area 1.5 hours later- this caused us to miss our flight because of the delay. I called Aer Lingus to see if they could help, but since I booked it through a third party on Kayak, they said they couldn’t help. Are you able to help with this? We needed up getting a hotel and renting a car for the solution.

The boarding process, airplane, entertainment, beverages and crew were very good. But the food left a lot to be desired, especially for business class. I had a chicken breast that was tough and rubbery, with little flavor. It wasn't even up to the proverbial "banquet chicken" standards. Very disappointing. There was only one offering of bread, OK, not a huge deal, but it's a nice touch to be offered more. Similarly, other airlines' crews come by to offer more drinks, though the crew responded when asked. Good flight overall, but the food just wasn't up to the standards you'd expect.

More options on TV shows and movies and make it where if someone wants to choose their seats that it is an easy process. I wanted to choose our seats and never could do that! I even called and they told me I had to do it with agent at the airport. That was very inconvenient

We were treated politely and the crew was nice. Again no one knew why there was a delay. Food was hot and a lot was offered but bad in taste. Seats weren’t the worst but for a long flight your legs ache from it. Entertainment was old not very interactive

I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.

This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

WiFi didn’t work for me. as headphones didn’t work either.

Canceled flight for unknown reason after numerous delays and only available flight was the following day yet no compensation. No weather problem. Then had to fill out form to get refund. American used to be a quality airline - no more, very sad!

Service was excellent with the staff they all did an fantastic job well done 👏. But the entertainment with the wifi service was very bad couldn't login to read or watch a movie. An also I couldn't get any rest because there was some ppl making noise talking along with kids was misbehaving. Also I prefer person u there head phone while using there devices . But it was a very smooth flight. Thanks you all 😀😀

entertainment choice was excellent for both movies and audio. Food was quite good. Staff was excellent and flight was on time and smooth.

The flight was uneventful, which is always good. The plane was clean and seem to have a little bit more room. They fed us every couple hours, and we had a lot of in-flight entertainment. The staff was very helpful and attentive.

Everything but the food was top notch value for the price

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

Flight was canceled due to labor dispute. Their customer service said I might be ok since strike was on sat. and I was flying Friday. The next morning it was canceled. It can ruin a trip and add stress.

Everything was excellent. Just keep doing what you are. I would travel with this airlines gain.

Flight was good. Really appreciate the second hot food offering. C

The chairs were too upright, but not awful. Boarding was fast and efficient and we did not sit too long in the plane before takeoff.

I didn’t realize booking through Kayak the pricing was in American fees and that I had to pay for my baggage when I arrived at the airport. I thought it was included in the price. For this reason I spent an extra $500. Next time I will book directly through the airline.

Kayak changed my Dublin flight and then changed it back to the original time before I left for Ireland. Unfortunately Kayak never booked me back on the original flight so when I got to the airport I had no flight to London. Very stressful. If I hadn’t gone very early and Aer Lingus staff so helpful it would have been a very wasteful day.

Great plan and with the two existing being used the off loading was quick! The seats could be a little wider. I am a 32 waist and I found it narrow. As well as the aisles were narrow so much so I had to carry my computer bag!

Everything was very excellent The food was great The crew was so nice 🥰👌🏽 I really appreciate and loved travelling with Air Canada 🇨🇦
