It was hidden that I needed a special fee to bring my guitar on. They charged me an extra 69 euros at the gate and did not refund me the checked bag I paid for and the over head bag I paid for which I didn't use because I had to pay for the special guitar case. Criminal behavior. They were very unkind about it as well. Terrible experience. I'd like my money back for the extras I paid for.

Delayed first flight Geneva Madrid.. We didn’t miss our 2nd flight only because the 2nd flight Madrid Dallas was 1h delayed. However we did end up missing the 3rd leg Dallas Austin. Luggage didn’t show up in Dallas. So we re missing 2 suit cases. Customer service sent us to a hotel in Dallas. Only one room booked for 5!! Pretty bad experience overall. I won’t book a flight on Iberia in the future

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

Horrible experience airline crew was unprofessional. Flight was delayed. Suit cases did not arrive. Never flying iberia again

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.

Delayed and missed connections on leaving the states and returning Planes were old and small- very uncomfortable. Meals were good but very infrequent service for even water/drinks. No explanations for 3+ hour delay

One of the crew members hit me with the car and not even says anything

Boarding on the buses isn’t efficient. Overall, it was great.

They need to start flying on time. We lost 2 days of our time because they delayed flight both ways.

This ticket was canceled and I did not find out until it was time to check in. I believe the vendor is at fault. Cheap tickets.com I would like to elaborate on the situation to kayak. Can you give me an email address?

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

One one boarding scanner was working to scan 400+ passengers to an Airbus 380. Food in premium economy was mediocre.

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

Flight was delayed and luggage was delivered day after arrival. In Bilbao they told me day after would be delivered faster if I went to Bilbao to get my own bags so I did. Wasted my morning.

Very friendly, service oriented and responsive crew. Very pleased with th service!

The crew was exceptionally polite and caring. The plane was comfortable. Great experience. Will fly more on Air India because of this experience.

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.

Service was bad and food they told us they only had pasta very rude

The media system is so inreliable, it keeps freezing and restarting at the begonning. Old planes with an old entertainment system makes a long flight very boring

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

Everything was good except the bathrooms were usually dirty and the trash bins in the bathrooms were full.

Better consideration for families traveling with a disabled person. They insisted each person hold their own boarding pass on their own devices and gave us a hard time accepting eight boarding passes on a single device.

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Two of my four flights had issues with toilets either NOT fully operational or completely out of order. Boarding was a joke because they have NOT established who is running the show. In the end, she did a terrible job. The seats 💺 were loose goose and the drinks and snacks were limiting in choices. Also, following Alitalia as an inspiration was strange since they went out of business.

Terrible. They canceled 2 flights and then sent everyone by BUS from Rome. They should make amends by offering some sort of compensation.

We ordered a gluten free meal and never got it!

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

The flight was great. I don’t know about the food because I was asleep and they didn’t leave me any.

There wasn't a time for neither food morning entertainment in a short one hour hop over.
