First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

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

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

All of my Aer Lingus flights were delayed. The seat I purchased with extra leg room was exactly the same as my previous seat that was free. I would appreciate my money back.

Horrible. I had to wait in Dublin for 4 hours for the next connecting flight which took my to London and than i had to wait 3 hours for the flight to Dusseldorf

It was fine. Not worth the premium price. Overhead bins were so high I could barely reach and no crew offered to help me. Average food. Lounge in Dublin - 51st and green- absolutely appalling. Plagued with hordes of flies, dirty, meager food and beverages. Shameful.

Dear Aer Lingus Customer Care, I am writing to formally raise a complaint regarding my recent experience on Aer Lingus flight EI53 from Dublin to Seattle on 22/08/2025. Both my wife and I were seated in 15D, 15E directly under a faulty air conditioning unit. Even though the unit was switched off, cold air continued seeping through the sides and blew directly onto us for the entire duration of the flight (over 9 hours). We reported the issue to the cabin crew, but the only attempted solution was placing a piece of food-packaging sticker over the vent. Unsurprisingly, this had no effect. When we pressed further, the crew told us: “It is hard to fix it because we don’t have an engineer on board.” As a result, my wife and I remained exposed to constant cold airflow for the whole flight, and both of us became unwell afterwards, experiencing chills, sore throat and fever at the end of the flight. This has caused significant distress, disrupted our work plans. This experience highlights both a serious maintenance issue and a lack of adequate care for passengers. We therefore request: A full investigation into the defective AC system on this aircraft. An explanation of why no effective remedy (such as reseating us) was provided. Compensation for the illness and disruption caused to both myself and my wife. We ask for a full written response within 28 days. Should this matter not be satisfactorily resolved, we are prepared to escalate the complaint to the Irish Aviation Authority and Commission for Aviation Regulation and other relevant authorities. Thank you for your urgent attention to this matter. Sincerely, Temuujin Tuvshingal Myagmarsuren Ganbold

We had a long delay leaving IOM. No food or drunk service as it is a short flight. Shuttled by bus from terminal to plane with packed in conditions on bus.

Excellent as far as the flight is concerned. Faro airport passport check was a huge delay and worrisome re missing the flight. 45 minutes there through passport control

The space between seats was reduced even further. Could not even open the tray table fully and got compressed the moment the front guy reclined. For a long haul flight it was extremely uncomfortable.

Not satisfying due to loss Luguage for 4days. Damage Luguage that had no way to fill up a report for and me as a client to spend more money and time to replace it. Thank you for soliciting my opinion, but it was unfortunately a very disappointing experience. Stephanie Zvi

Delightful flight, ahead of time with a super crew, thanks

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

What a silly survey to send - all AC flights were cancelled due to the strike so of course we did not fly yesterday

It would have been better if it wasn’t cancelled

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.

I wish to travel with Air Canada for my next trip

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

Great flight ✈️ I requested a vegan meal and don’t think offering frozen fruit cup for breakfast is a good idea people want something warm or neutral like the muffin but it was cold from being in the paper bag with the frozen fruit 🧐 and unfortunately I didn’t have either and I don’t like wasting food so that was a disappointment. Flight was on time departure and arrival flight crew were good.

Flight was in business class on an older Lufthansa 747. Business class seats definitely old style. Flight attendants were a little curt but attentive. Movie choices did not include anything that would be considered new releases.

My luggage passed security but just before boarding the plane I watched as my luggage was thrown on the belt to enter the plane in Windsor and my luggage cover was half off. it was damaged before even making it onto the plane! I’ve had the luggage and covered for a year and have never had any issues. I mentioned it to an Air Canada employee who told me to use the app to make the crew aware of this (she said so they could fix it) but sure enough my luggage was damaged with no cover in sight! I sent an email to AC that was ignored. Awful experience! Also, a 4.5 hour flight and you are offered pretzels or a cheap single cookie?? Wow. The return flight did not have any entertainment available unless you used your own device and their wifi. The USB plug on the back of the seat did not charge my phone so my battery drained by using it for a short period of time. There was no warning that this was the case prior to boarding the aircraft. Lastly, the plane was freezing. I asked if they had any small blankets (which used to be standard) and was told they were only for the front section. Would never fly AC again!

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

They sat my 2 year old in the seat behind me, separate from myself and my 5 year-old daughter. When I asked them to fix it they told me to speak to the gate agent in London. When I asked in London they told me to talk to the cabin crew. Then a “Supervisor” stuck us in row 39 at the back of the plane when we were originally sitting in row 25/26. They ran out of food which was gross anyway, and the entertain didn’t work the first hour of the flight. Overall terrible experience.

The crew were good. The flight was on time. The food was bad.

Flight from LGW to JFK delayed by 4 hrs No explanation given until the pilot said the delay due to planned maintenance on the aircraft

More Indian vegetarian food options would have been better Availability of seat selection free of charge 72 hours before departure would be great

The payment system was not working so was unable to connect wifi the entire flight

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.
