Airline reviews

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

It was budget airline Veuling, even though we booked Iberia.

Suddenly, I don't find my flight back on the app Help Ticket 0757345716866 Hoeflich Flight back Sunday ib5333 Ib2629 Ib4268

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

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

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

This is where i leave an airline review. Test test test!

The crew were not very personable. The crew did not serve tea or coffee. The bathroom was not kept clean. Two out of the 5 toilets in the cabin weren't working.

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

My long-haul flight experience with this airline was not very pleasant. Earphones were paid, and no eye mask or other amenities were provided. The meals were served in cardboard boxes with plastic cutlery. The restroom was unclean and ran out of toilet paper. However, the boarding process was smooth and well organized.

We experienced a delay of almost two hours before takeoff. For a flight of more than 10 hours, sitting on the runway for two hours is quite exhausting. The airline did nothing to attend to the passengers during that time. We were not given any courtesy drinks or snacks—only the bare minimum during the flight. The crew seemed very apologetic, but apparently they have restrictions imposed by the airline, because despite their friendliness, they provided strictly what was necessary and, of course, everything else was for sale. However, after a two-hour delay, one would expect at least complimentary beverages. In addition to this, the space between the rows of seats is inhumanely narrow. Air Europa should review this for such long flights and be a bit more considerate and humane with its customers.

I flew in business a couple of months ago, it was great, tried again in economy, it is the cramped seat I have ever been into, for an overseas flight across the atlantic it is inhumane to put passengers in such cramped space. Other than that, everything ok. Took a second flight from Madrid to London, also economy and it was roomy and perfect.

No WiFi on the plane. Crew was insensitive to my medical supplies and medicine in my carry on. If the crew was monitoring passengers putting 2 bags in overhead bins there would be room. We sat for 2 hours extra. Iberojet is horrible never again.

There was no water in one of the sinks in the executive area, which is unacceptable as we could not wash our hands after using the restroom

Like I said the experience was mediocre. Nothing special about this airline.

This flight was delayed by more than an hour. The seats are uncomfortable ans do not recline properly. I prepurchased a wifi pass, but wifi was not working on this flight at all. The food was bland.

Food situation was bad. Also movie choices when compared to other airlines was terrible. Seats very narrow. My tv didn’t work.

I was not allowed to cancel the flight, customer service is atrocious

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

Flight attendant really had bad behavior.. yelled at people when she is trying to defend, to have favor w her people..!

They lost my checked in bag and have not helped me.

First, ITA lost my bag and the baggage team showed no regard in trying to find it. Second, I had paid for priority boarding as part of a first class ticket and instead they disregarded boarding groups and we all boarded at the same time. Third, wasn't allowed to select my seat in advance even with a first class ticket. When I was assigned bulkhead, I was told I would need to pay to change my seat. Overall, very disappointing experience.

Inside plane needs to be updated, the lady sitting behind me was saying the frame from the window fell on her lap right before taking off and seats are very uncomfortable, cushioning is need of repair ASAP.

The seats needs to be spruced up , for a long flight very uncomfortable , cushions are worn out but everything else is very good , crew is great.

I guess that was fine with ITA but the Rome airport is so difficult to navigate with so many checkpoints getting new tickets from what was originally given to me

I did not leave to Italy yet. We had technical problems on flight from SF to Maimi and had to land in Denver and wait for another plane to take us to Miami, so I missed my plane to Italy. I am still waiting for the Agency to fix my flight till today the haven’t done anything and I am paying for my Hotel stay. Everyday they are promising to fix my flight, they are not doing so and they are not even looking for another solution

This airplane is much better. Not worn out like the one we flew with fr NY to Rome. Flight attendants were ok.

This was our return flight. It was slightly better than the one we took to go to Rome, mainly because the food was slightly better and more abondant. On our LA-Fco flight the food was way below average. Also, it felt like the legroom in Economy was smaller than other airlines we used in the past - my knees were touching the seat in front of me.

Pretty normal flight was delayed due to traffic could have missed connecting flight to Venice but crew kept us well informed so we made it
