Everthing ok , crew very nice but but we had a bad experience with the wheel chair we had to wait too much for the chair, my husband couldn’t walk and he was in lot of pain , LATAM has to take care of that

It’s been some time since I saw the plane and the cabin that old and worn out.

Flight was great Customer service was questionable until we found someone at checkin to help us. One young lady took all our passports disappeared for 15 minutes, came back with nothing done, handed to someone else and left for lunch. Very complacent. Baggage was very expensive until we went to the service counter and a separate person helped us. Even with platinum status they wouldn’t allow free bags. We will continue to fly Delta as our preferred carrier but will avoid checking in with Latam. Dr. Armand Radke

Flight from Lima to São Paulo didn’t have USB plug to charge the cellphone.

It was ok for the most part, it is missing something

Liked check in process To improve: food and beverages. Not second round was offered and meal had no salad.

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

Our yoga retreat was cancelled and besides not refunding is, they would not even let us change dates or locations. As a matter of fact they wouldn’t even talk to us and kept referring to the travel agent, who said they couldn’t change anything and it was up to the airline to do so. They passed the buck until it was too late to do anything about it. Avoid Latham and Budget Air for your travel plans.

Pros: "Nothing as we could not take the flight."
Cons: "Allowing the option to change your ticket date, but failing all debit and credit cards payments offered, actually means that they are not allowing flight changes due to COVID related issues like they say they do. We had to book new tickets with another airline to get home."
Pros: "The seat was comfort, good attention, flight on timing 😇"
Cons: "In several times the plane went down and up, and I think the pilot had no experience or it was the first time flying"

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

I’m hoping for WiFi included. Everything else was very good

All corners have been cut and it’s a cheap experience that no longer is distinguished from most other cheap airlines

Both flights were delayed. I lost my connection on the way back. No voucher or anything was givenx I had business ticket and no support to make it on time. I got to the door running 5 min after they close. Food really bad. Breakfast in business was worst that I what I remember in economy. Even though I have accumulated many miles, I don’t think Inwill keep buying Iberia. I am a frequent business traveler.

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

it would good to have at least something to drink...

Everything was fantastic except the Iberia website and app… they left a lot of questions and induced much stress. But once on the plane, all was awesome.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

Changing the flight with app and customer service was very difficult and poor .although I h ad a ticket and seat number still had to pay more money as ticket not transfered. Couldn’t buy another ticket for my daughter on my booking too. Customer services’s appealing. My daughter was ill and noine cared.

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

Only two check in counters for online bag drop, economy and premium economy clients, NO management supervision whatsoever, no announcements, whilst Business and first class had three check in counters operational, with the bulk of clients flying economy on a 747…..very poor service indeed. Stood in a queue for two hours to check in!!!!!! The flight crew were equally indifferent.

Terrible. This airline will cancel flights at very short notice.

Plane was old and the persons chair in front wasn’t easy to move up so he had it back most of the flight including during meals. The touchscreen was not working well and selections weren’t good. First time on a flight I really had a hard time finding something to watch. The crew was great and without them, it would have been a bust. Pilot got us there in record time.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Some how I got “offloaded” even though I had my boarding pass Food was horrible Staff were nice and cheerful No headphones were provided

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very Stress free Lounges were superb. Crews were caring. I loved it.
