Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Our flight from Dublin to Coruna did not exist any more. Apparently it was cancelled in February and I was not advised, nor was I offered any flights for rebooking. Happily Aer Lingus found another flight to another city in Spain that was 500 miles from Coruna; I had to pay for a hotel overnight and a revise my rental car that incurred additional costs, and I did not get to Coruna for another 24 hours. I was not at all impressed with Kayak or Chatdeal or Hertz.

Satin first class and absolutely no snacks are offered. Surface was awful.

This was the smoothest flight I've ever taken with any airline, including Aer Lingus. Typically, there are moments when I feel afraid, but from take off (miraculously seamless!) to cruise, to landing this was a perfect flight. Thank you!

Poor. Plane left EWR late hence missed connecting flight in Dublin. No pro active info from flight staff on connection, only when probed a couple of lies on where we would dock, and on lilelyhood catching connecting flight. Lies as they will have known our EWR-DUB would be parked furthest away from the transit spit - lying it would be next to the AMS flight.

The seat area was way too compact. The person in front reclined, and the TV screen was right in my face. There was a metal box secured to the floor in my foot area, further limiting space. Food was OK. The last service was provided too late in the flight, so the crew was rushing at the end. The ticket counter in the Naples airport was extremely slow. The staff on the flight was friendly.

delayed flight stayed whole night at washington Dallas airport at seats , uncomfortable . i am senior citizen , very tired , worst travel.

I heard that the pilots were actually leprechauns, but I was not able to confirm. Can you please provide documentation if this is true?

The check in process at the front desk felt slow and it was frustrating that we could not check in online. Everything about the actual flight was great, including very kind flight attendants and a nice larger bathroom. Only thing is that it was very cold in the plane!

I flew economy class. Seats were very good and the crew was excellent

I had a great experience. I would definitely use them again

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

The crew was very attentive through out the flight. Seats were comfortable, nice flight bag with pillow and blanket. Food was okay, since it was a overnight flight seemed to go by fast.

The flight attendant on my side of business class seemed like a novice and did not provide good service. Otherwise the flight was good and the entertainment system was very good. No free WiFi.

Cancelled BOYH legs of our flight home 30 min before initial boarding

Cancelled the flight half hour before boarding. Then cancelled the connecting flight too.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

In general, I've had excellent experiences with Iberia flights and will continue to use them. In this last flight there were two things that didn't go right. I didn't get the kosher meal I had pre-requested when I had checked in on-line. Things worked out OK as we ended up eating the fish and vegetarian choices, which were really good. The other issue was that some movies for me and my wife started fine but after 8-12 minutes the content just switched to something else. The flight attendant reset our entertainment systems, but the problem persisted. We ended up choosing other movies/TV shows that did work fine.

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Really like the idea experience on this airline I will use again

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

the seats were so cramped you could barely move. it was difficult to eat when passengers would recline their seats. the seats were so flimsy and unstable that whenever someone got in and out of their seat, it bounced like a spring back in your face. the movies were nice. the food was terrible. even though the conditions were terrible, they tried to pressure passengers to relocate their seats to accommodate adults who were related and wanted to sit next to each other, even after the passengers expressed that they did not want to move for that purpose. on the connecting flight, the “service” consisted of items for purchase. even though the flight was only 45 minutes, once again passengers (including me) were pressured to relocate for people to sit next to each other. they couldn’t be apart for 45 minutes? this was much less compelling than being apart for an 8 hour flight.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

The staff was very nice and helpful. Some of the best crew I have met.
