The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

Really bad experience – delayed for 6 hours without any notice, no food or drinks provided, and stuck in the horrible Cartagena airport.

Boarding was confusing with a delayed flight because there was no English translation

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

Horrible the worst airlines I have ever flown. Cancelled flight with no choices and when contacted them they were not helpful

My entertainment did not work. I was very tired from the botched connection, and the poor sleep

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.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

Need to pay for headsets, water, or any extra except air to breath.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

Sitting space was very tight, so eating was difficult. But everything else was good.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Need to pay for a cup of water. No food. Need to pay for headsets.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

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

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

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

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

Food was terrible. Going to Italy I gave benefit of the doubt however returning to the USA was no better. Rolls were frozen. Butter was frozen. Quality of entree poor

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).

It was fortunate that the flight arrived in London in accordance with schedule, and the luggage was promptly transferred to the luggage carousel. However, I find it concerning that even minor issues in economy cabins are prevalent within the industry. American Airlines, in particular, appears to have the least legroom and feels more crowded due to the proximity of neighboring passengers. Additionally, the crew’s adherence to protocol is inconsistent. While they may enforce certain rules set by the FAA on a select few individuals, they often overlook numerous violations, such as failing to reset seat recline during landing.

Easy and organized getting in and out of the flight

People point to America as the model of late stage capitalism. My friends, airlines in america at least give you WiFi, and they haven’t quite smashed people into cardboard tv dinner trays yet. Iberia has mastered the tv dinner seat and WiFi is 20 euros. Be serious yall.

I described my experience in the previous window. I didn't realize that there would be another opportunity for this flight. Please look at my response in the previous window.

Wonderful! Everyone very helpful and kind. Returning flight was cancelled but rebooking was easy.

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

-The seats could be roomier -The entertainment in English could be more current! The moves were very old!!! -They served too many carbs! What happened to fruit and yogurt!!!!

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.

Staff were nice, we left on time and arrived early, food was good. Unfortunately, they lost one of our bags and have been unable to find it. So we are in Italy for a week for my husband‘s birthday and he does not have any of his clothing.

They gave us sandwiches as a meal twice. Snacks mid flight with cookies and a tuna panini. Then just the same tuna panini for dinner. That was it.

The staff was very good, the only thing was the air conditioning wasn't working during the boarding process so it was very hot inside the plane until we got airborne. The food wasn't great, the chicken was dry and hard to cut, the ravioli was ok and the little pizza pocket thing was pretty bad. Other than that is was a good flight all around

Flight bumpy and aircraft old with tape over seats , it seems there is a lack of maintenance, air pipe blow off in the middle of the flight, flight attendant seemed not to be worried about it. Food got very bad over time , not only for the quality but for the quantity . Seats are very uncomfortable , entertainment not working properly.

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

The flight was comfortable and the attendants were readily available and helpful. The food needs to be improved.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

Overall, it was basically good. No serious complaints on my end.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The aircraft was okay and the crew were friendly, but the seat space felt too tight and the food could be better. Overall, nice service but room for improvement.

The flat beds. Other than that, the place was not clean.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

Good but could be better for comfort and entertainment aspect

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor
