Seats too small. Really uncomfortable if neighbour is fat or simply selfish and invades your space.

Everything! Not sure if there's really anything that could make it any better

Very quick trip from Southampton to Edinburgh Arrival a long way from baggage and up 3flights of stairs no lifts or escalators

Cons: "The flight was cancelled and we were asked to leave the departures lounge. There were no Logan Air ground staff actually working so we relied in the customer services desk at the airport to give us direction on what to do, and we were told that we would be eligible for compensation. I have now been told ( almost 2 months later) that the flight was only delayed and not cancelled so we are not getting a compensation payout to cover the huge additional cost I had to spend to fly another airline to get me to Aberdeen. Awful customer service, unreliable flights"

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

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

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

I travel frequently. The flight was late again... KLM should really try and be on time

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

All and all pretty good. It’s crowded but that is what flying is all about. But no complaints otherwise.

The seats are too cramped in that plane. If you’re above 1,80m consider alternatives or first class I guess… There were no emergency exits to seat somewhere with more legroom

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Short flight so not much to rate. Surprised I had to pay for a soda.

Very good need to offer better choice of food for business

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.

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

They lost my baggage on my connecting flight and we’re an hour late so I nearly missed it

All OK. Food, best bring your own. Even a BigMac will be better.

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

Flight delayed a bit. Boarding by seat row number in two parts. Flight attendants weren’t greeting boarders, they were talking to each other. In the outward journey much the same yesterday and that was a different crew to a different airport. I do get the feeling on Blue Island Flights that they have no interest in even allowing passengers to use the toilet . The flights are short but in fact they keep the seatbelt sign on for the duration.

Basic economy flight, random seating unless you pay extra, no refreshments, friendly and attentive crew, slightly late boarding and taking off. 40 minutes max all in

As someone who has limited mobility it was appreciated that the staff took particular care to ensure that my needs were catered for with priority boarding and assistance both on and off the plane.

Cons: "Delayed for 2 hours due to “fleet issues”, no food or water on board due to “weight restrictions”"
