Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

We departed and landed on time, the aircraft was clean and comfortable, the crew were lovely. Online checkin worked well and the self service bag drop at the airport worked well. The a/c was an Airbus A330 and has been fitted with a good entertainment system with lots of choice in many languages. The price I paid for the flight was competitive with other airlines apart from the budget carriers, none of whom I was familiar with so I stuck to an airline I have used in previous visits to South America.

We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

Plane never left the ground. Mech issues - entire trip was rerouted through united.

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

I paid to upgrade to Business Class. The queue to check in at the Business Class aisle was full of people without Business Class tickets, the fast-track immigration line was “closed” but the representative opened it up for his friends, regardless (there was a lot of fist-bumping), and the lounge was an absolute mess…..4 staff sitting playing with their phones while every table had dirty plates and glasses waiting to be cleared…..and the least said about the rude lady on the reception desk at the lounge , the better!

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Keep in mind that for some maintenance error I could not check in online like I usually do. Personnel at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

Great food, excellent service. Did not manage to make wifi work but in a flight of less than an hour it was not a big deal

I didn’t have food and they don’t include entertainment. Not much leg room at all. Staff were great.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

charging port did not work, no entertainment system. Other than that the flight was good and safe.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

When Stephen arrived with our wheel chairs - we were in excellent hands! He was such great help with getting our rental car and then reporting our missing luggage. When you are exhausted from traveling for too many hours, he was just what we needed to navigate everything! Give that guy a raise!

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

Gate information deliberately delayed to only one hour B4 flight, lack of info finding gate.
