The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

It was a long and boring flight with no entertainment and no meal only a drink and very bad bag of chips

The crew was super friendly and respectful, they made me feel well all the fly , thanks delta

The crew was amazing. The best in the last times. Great group of people.

Check-in was a total disaster, almos a full hour in the line

Just some cookies and water. There could be other options for food.

Airline lost my luggage and after 20 days it has not been returned nor refunded any money.

They offered food. The crew passed by again offering water. I enjoyed the two seating section. I think is very comfortable instead of the three seat way, unless you seat in the middle; which it's not bad, but I wouldn't prefer. All and all, I think the lay out of the seating rows are better than other airlines so far( I haven't tried many anyways). The lay out makes the getting in and out to use the restroom less uncomfortable and cramped. First time flying with Latam. I will fly with them again

I do not read or speak in Spanish. Only English. When asking for help, the people spoke quickly in English and pointed a lot. I wish they would’ve spoken a little slower for me to understand. There was much confusion and hurried in their message and I was unclear as to where to go

I didn't realize they didn't have bathrooms on the plane. Almost had a very bad situation.

The insanely long lines at customs were chaotic and stressful. They also created a lot of stress among passengers. Including fights and threats. The hot food I purchased was cold, barely edible. The check in staff and crew were nice and the pilot good but the overall experience was very disappointing. Passengers were still insulting each other upon arrival.

No frills airlines. Tickets were reasonably priced for a short-term booking. But comfort is a big issue.

It was just okay. They overcharged me for a checked bag because I didn’t know it wasn’t included in the airfare.

Very small dinner, NO breakfast. You have to buy an earphone.

Food was terrible. No breakfast. Will not use this airline.

I'm not going to travel with that airline again.

I travel on a monthly basis and I’m not a stranger to budget airlines. I never complain about anything, it just about adjusting you expectations to what you paid for and you will get, but these flights (2) with Air Europa Miami - Madrid - Athens were a terrible experience. Both flights had a significant delays and multiple gate changes. At the checking they used a hand scale to weight your carry in, it cannot be more than 10 kg , even it fit on size.Luckily mine was ok . The food was inedible. The staff service was ok, but you can totally tell they do not care about much and show little customer service culture. I think this was my last trip on Air Europa. Actually the price was almost the same than other major airlines, I just took this one because I needed to depart late at night.

Probably will never use this air line again. Rude miserable staff. Uncomfortable seats.

Well, I'm not too happy with the service a flight for 9 hours with only a cup of water or wine. Food only service you one-time I bind flights many different airlines and they make sure that you feel comfortable with the food and drink

i paid accidently for a second bag instead of a golf bag (Eur 40 instead of 50) they would give me credit when i tried to change the second bag from a regular suitcase to a golfbag. The comment was "you made a mistake, your problem"

The boarding was a nightmare. Iberia would not let me check in in advance. They then refused to issue a boarding pass in Paris and said I would get the boarding pass in Madrid. In Madrid, there was no transit desk, no help. I had to run around and find someone to issue the pass. I only had an hour and risked missing the connection. Only at the gate did Iberia tell me they were overbooked and had downgraded me. I was stressed, exhausted, almost missed the connection because of Iberia’s conduct. Unacceptable.

This was such a bad experience. Iberia in Paris Orly refused to issue the boarding pass for my connecting international flight. They were evasive but said it would be dealt with in Madrid. In Madrid there was no help, no transit desk, I almost missed the flight trying to get the boarding pass and only at the gate they told me they had downgraded me. I really felt abused.

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

Worst flight in years.. is not easy to flight 11 hours without entertainment onboard and the crew was not empathetic about it or even gave an apology for the inconvenience. Poor treatment to the passengers, and some responses where roughly given.

I fly to BNA with BA often and this was the worst experience. Arriving in nashville, check in was 1.5 hrs long in the queue with 1 very slow girl at the desk. When more staff came they only catered to priority customers. When all priority were checked in, instead of filtering from the top of the line they took the people from the end, the people who had been queuing for 5 mins vs almost 2 hours. The flight was delayed, for no good reason other than the staff took forever to do anything. At the gate there was zero organisation, we asked the crew what the delay was and they confirmed it wasn't the plane and it was the ground team. One of the flight attendants was one of the rudest I have EVER encountered, that man clearly hated his job, and people...I wish I'd got his name. Food was disgusting, seating was cramped. I've no idea what's changed in the last year but I'm truly shocked.

British Airways changed flight times after booking, allowing very little time between connections. We had to rush to barely make the next flight. They also ran out of certain vegetarian options during our 10-hour flight. Crew was fine, but overall a very unpleasant experience.

Being a platinum member and having reserved an exit row I was bumped into a middle seat which should not be allowed. On top we landed 10 minutes early to wait 45 minutes on the tarmac at Heathrow. I used to love Iberia, loving it less and less

I had assist travel booked in Denver to Manchester, but not listed in HeathRow, my daughter use a spare wheel chair herself for me , when going thro to board at Heathrow there was no help travel down for the ramp until a member of assistance stepped forward and insisted he would take me down the very steep ramp, seems he was the only person concerned with my safety.

Booked Economy Premium the 3 seats with my daughters and I, the seats should have been able to tilt back but it only one worked. the crew said they would report it but didnt seem both about our comfort on the return journey.#

Better pillow cases in economy. I didn’t like that I couldn’t pick my seats since I booked with Kayak.

Lufthansa only flew me to Larnaca. I had to find my own way from there, and am out of pocket for a ticket and hotel expenses

It was terrible, I was denied to board the plane because I don't have Germany visa, but I don't know I need a visa because all I want is go back to united state and I don't need to enter Germany. When I buy the ticket and checking in I entered my Chinese passport information and I did not get any notifications that I need apply for Germany visa. This trouble is generated totally by Lufthansa and they don't offer any useful help to solve my issue which cause huge problems to my travels.

It never happened. Bumped 2 times then cancelled. 4 cancelled flights after that

Missed our flight to London and we were put on coach seats to Munich.

The flight was wondering, especially the special assistance from airplane to airplane!

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

No refreshments apart from a bottle of water. No pillows. No entertainment. Flight delayed by 52 minutes.

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

The Lufthansa part was wonderful. The short connection flight was not.

One particular crew member wasn't helpful in the cabin .

Check in staff were rude and argumentative with most passengers. Overly scrutinizing with baggage allowance. Delayed, again. Becoming the norm with BA.

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

Staff and crew where very nice and friendly. Just need to improve the timming om the meal and beverages.

3 hr delay. No water given while on the plane for 3hrs.

Excellent except for checking in at Madrid Airport. Waited in line for over an hour and a half. Not enough ticket agents available and they were moving those with earlier flight times up in order to get them through. People were not happy. Staff did their best to explain, but just not enough to meet the need.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

The whole experience was great. The only improvement would be the entertainment selection

I will travel by BA only in future also. Only suggestion is they should give aisle seat in front near washroom for senior citizens

Flight was fine but diverted to a different airport. I was also assigned a seat that I wasn’t allowed to change during the check in process, which was odd.
