Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

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

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

It was nice to be on a legacy airline, people try at least.

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

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

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.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

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

At the transit could be less time not like 12 hour 6 hours the mix should be 4 hour, thanks

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

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.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!
