The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

For what we are willing to pay for international air travel, our experience was very good. We had no problem checking in, we had very little wait time at the AA counter in Madrid, and the staff in Madrid were very helpful. The flight crew was helpful and courteous, the plane was on the newer side, and our assigned seats were together without us needing to purchase them. The flight took off on time and arrived early. Overall, it was a pleasant experience or as much as could be expected in economy for almost 10 hours.

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

Boarding was easy, the flight left on time and even landed 20 minutes early. The food was plentiful and really good! The crew was kind & helpful. Overall it was an exceptional experience!

The flight was safe, confortable and convenient. Thank you. I hope to come back soon!

Delayed. Mismanagement of gate lines. Passengers arguing with eachother as a result of lack of organization by airline. Avoid this airline.

Because the plane was delayed from Madrid to LAX, we missed our connecting flight to Malaga. Iberia offered to book us a hotel room but I needed to be in Malaga that evening. I ended up buying train tickets to Malaga from Madrid. I also feel Iberia should compensate me for the cost of the train tickets because they didn't meet their travel obligation.

Terrible. Won’t fly again. Boarding was an issue. Took TWO hours to “find” my confirmed reservation. Crew at desk was super rude and unconcerned. Was not escorted through despite delay on their end. Almost missed fight and luggage arrived one day late…. Which I had to pick up by cab or wait even longer (not reimbursed).

Arrived on time. Great crew. Good food. Luggage delivered promptly

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

Overall, it was basically good. No serious complaints on my end.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The aircraft was okay and the crew were friendly, but the seat space felt too tight and the food could be better. Overall, nice service but room for improvement.

The flat beds. Other than that, the place was not clean.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

Good but could be better for comfort and entertainment aspect

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.
