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.

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.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

Even though I flew in business cabin I was not given any refreshment even though those next me were served

Not great - seats were very narrow and food was terrible.

They didn’t have my special meal I requested. It seemed like they just put a sticker on a veg meal for me. I had a little bit of it but it didn’t taste good and I got sick from eating it by the time I boarded my Frankfurt to NY flight

boarding and flight very smooth. Crew very friendly and efficiant. Everything worked well

The crew on my Frankfurt to Chicago flight were outstanding!! Friendly, helpful and worth taking the time to write an excellent review on their behalf. I would fly Lufthansa again just because of their warmth, kindness and humor!

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

Size of economy seats great. Food well not bad for airline food. Staff friendly, helpful, professional. Very impressed

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Everything went well. I will fly with Lufthansa again. And use Kayak whenever I book flights

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

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.

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.

Flight was on time and pretty standard. No Hiccups. I have no complaints, which is a lot to say about a 12 hour flight.

On both sides of my itinerary, the planes were old, the seats did not work, the seats were filthy, and the crew were unfriendly

Everything was much better than I had expected, since I hadn’t heard of your airline before. I hope to take advantage of your excellent service again.
