Airline reviews

The pilot was professional and very good. The flight crew, very young and often looked flustered and overwhelmed. The seats were among the most uncomfortable in the air. The boarding somewhat chaotic. The price reasonable. Overall it was an average budget airline experience...although Iberia is not a budget airline. I fear if Iberia doesn't up it's game customers like us will go elsewhere.

30 minutes still don't have gate number, ask many people can't get answer.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

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

Flight to get to Barcelona was cancelled and then the next flight was overbooked. Cancelled the entire trip and went elsewhere. Fighting with iberia to get my money back. Ill never book this carrier again!

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

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).

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

Good Poor. service onboard No food. Low quality for economy plus

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.

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.

The flight was canceled and we have not received the refund

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

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.

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

Need better food options. Need warm food both times Stevie was provided. Bathrooms are too small. For an international flights, seats are small and leg room isn’t enough. And for an international flight, serving spirits should be included, not just Italian beer and cheap wine. All the tv/film entertainment is quite old and not updated, but the size of the screen was good.

Awful cold sandwich, pizza was bad and coffee was extremely cold I expected better quality in wines on the way to Rome I order red wine and could not drink it ! Bad quality of wine . Being an European airline’s wine are inexpensive so could have better selección of wines . So on the way back a settle for water with is a pity . The crew disappear and didn’t pick up the trays after meals or the garbage of the snacks . Iberia has better service and other airlines

Poor. The airlines left my luggage in Miami. It took 2 1/2 days to get my luggage at my destination. I was forced to buy clothes and daily items for days. There was little concern to get my bag to me which highly impacted my trip. Seats were cramped as well. Would not recommend this airline to anyone.

The check in process is chaotic. It says partially checked-in. Never heard of such a thing. Then lost our reserved seats when we finally checked in at the airport. The seats don’t recline. Then we had to get mew boarding passes at the connection. Last, my companion lost her baggage and up to now there’s no update. We’re already half-way through our vacation and still no news what happened to the luggage.

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

Flight was on time, there were no issues. It was also direct to SFO. For an international flight, I call that a win.
