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.

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.

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

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 professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

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!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

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.

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

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

The seat pitch was a little tight for me, but I survived. There was a volatile, enraged passenger a couple of rows ahead of me and the cabin crew defused and resolved the situation calmly, quickly, and successfully.

Comfortable trip , flight attendants professional as always. Only complaint was the food, We fly Aer Lingus frequently, this was the first time the quality of the meal was poor.

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.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Charging for coffee on a business class fare??? And to not even mention it? Inexcusable. Boarding and disembarking was pathetic. Could not use a jetway on either end. Had to use stairs and walk across tarmac at origination and use stairs and be bussed to terminal at destination.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

I meant this flight was not good, the one from Tirana to Frankfurt was better!

Exit row seat that cost extra to book had a bad monitor marked as out of order, so clearly something they should have fixed.

Everything was perfect. That is the most beautiful flight over thenDolomites.

The plane was over an hour late taking off... the plane was rather tired looking, seat cushion was thin and uncomfortable, the sound on my entertainment system wasn't working... crew are not friendly.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

I pre-ordered my meal and did not receive it. The seats are very old, uncomfortable and dirty. The crew was excellent and made my stay on board comfortable and enjoyable.

Professional crew and staff, very organized boarding and on time flights, baggage handling. Indian vegetarian meals were good, though could improve by offering Indian bread (naan/paratha/roti) as well. Very helpful pre flight emails with details of onboard experience 👍 Above average selection of movies. Consider offering more movies with subtitles and ratings indicators (e.g., IMDB scores).

I have flown with many airlines. My first time was several years ago. Now I remember why I avoided them for so long. Lufthanza is the only airline who has ever raised a size/weight issue with my modest standard size carry on. I had to repack three times to meet their carry-on weight criteria. (Apparently the rules of physics apply differently on Lufthansa flight than on other airlines.) In the meantime their staff was quite rude, repeating meaningless phrases like "Rules are Rules." And ignoring the additional fact that weight is also weight, whether it is in found in your carry on or in your suitcase. They eventually acknowledged that customer service and satisfaction is, for them, a low priority. Never choosing Lufthansa again.
