It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

On board crew was very good. Crew was friendly, snacks were good, especially the chips. Seats seemed a bit cramped. Boarding seemed unorganized, as we were instructed to get to the gate an hour early and then just stood around until boarding.

Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

We were not allowed to carry a bottle of water onto the 8 hour flight.

There was a mechanical issue with the plane that they had to work on before we could take off. That's fine, by all means, PLEASE make sure the mechanics are functioning properly. What was a problem was the fact that we sat on the tarmac for 4.5 hours without moving, without letting us off the plane, and without climate control and air running through the plane. There was no explanation as to what was going on; they just kept promising that it would be "15 minutes, then we are on our way." At one point, they even switched the entire crew out and told everyone we just needed to wait for new employees to show up. Then, as the 4 hours were not moving, an hour before the full refund, they made a big show about "the flight starting and the doors are locked, so you have to sit down." We didn't move for another 40 minutes; they were just trying to skirt around legalities that entitled us to restitution. When the flight finally was underway, the plane was gigantic but cramped in design, my entertainment screen kept freezing and glitching, and subtitles didn't work, and the crew was passive-aggressive. Terrible flight.

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

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

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

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.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

Bad weather Excelent pilot Spoke British 😆on time seats small ad expected in a discount airline

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.

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

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.

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.

BA is a fine airline. The problem lies with XCOVER INSURANCE, that KAYAK uses. Very poor service from insurance. No telephone number to contact XCOVER. Their replies are inadequate & overall very bad insurance. I wish kayak uses standard insurance company., such as AIG.

British Airways offers amenities subpar with all other airlines flying internationally. Sharing tis based on my experience with flying at least five other airline between IAD-DEL in the last six months.

The worst parts were not BA’s fault. The chaos of passport control etc was totally unnecessary. One of the Officers who was stamping passports (remember that) told me that if I had a problem, I should contact Boris Johnson! Secondly, the distance from the Lounge to the Gate was beyond acceptable. All in all, the issues with immigration and emigration and the hikes within the airport mean I won’t be returning anytime soon

Worth every penny to upgrade to BC. Treated and felt more like First Class

I missed my flight because I was sick and the medicine the chemist provided made me sleepy. I had to pay $3500 to get home because you classified me as a no-show and would not listen to me otherwise. In addition you wanted to route me through Dubai, which was under siege by the time I arrived home and would’ve been in trouble. Had I taken that route

Limited entertainment. Music - very limited variety of music. Suggest more options in Hindi, Telugu, English for flights leaving from Hyderabad.

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Food was good. For a long haul flight, there was “0” zero entertainment! What a disappointment. I do try to avoid BA. Next time its Emirates via Dubai to Cairo.

The internet was working on both sectors of the flight so hard to take the flight if you are on business.

Delays on take off, delays at gate on landing, lugging lost to the ether. power on seats not working, couldn't work due to that and no WiFi. The crew was great and boarding was orderly if confused and rushed.
