Because the flight was late, we lost the connection to Brazil. You, Delta delayed, and you Delta anticipated the door closing in 15 min from Miami to GRU. Why? It caused a lot of stress! I almost could not see my mother in law alive because of your delay.

Because the flight was late, we lost the connection to Brazil. You, Delta delayed, and you Delta anticipated the door closing in 15 min from Miami to GRU. Why? It caused a lot of stress! I almost could not see my mother in law alive because of your delay.

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

Lost ,y connection due to a mechanical delay, huge line to get new connection and vouchers

It’s a delta flight operated by LATAM. The whole ticket sale is a mess, delta changed my flight but didn’t update it in LATAM system, I couldn’t get my boarding pass, it took me hours to resolve this issue with delta. I had to change my travel plan. No apology from Delta even though it’s their fault.

Wider seats, better seat cushions, (I felt like there was a board I was sitting on). I had the chicken to eat but It neither tasted nor looked like chicken. The fruit was good.

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.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

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

The flight was delayed over 4 hours. Business class is just slightly upgraded economy.

I liked the comfort of the plane. It was unexpected from past experiences.

Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.

Moved the flight an hour later, were not reliable about confirmation, website didn't work, no gate information, boarding was a mad house. Flight itself was fine and short. Organization needs work.

Paid for my seat 4 months ago. Did not pay the extra for specific seat assignment ( never have and never was a problem). Could not electronically check in (found out it was due to overbooking and that unassigned seats get bumped first - never happened to me before). Luckily, did make the flight. Very stressful - would have been extremely disruptive for my travel plans. UK Visa - never notified by Kayak or BA that a visa was required. Had to spend 15 minutes to download and complete app at the flight counter and pay $25, and was told they would let me know in 3 days if I would get it (flight landing in 10 hours from when I completed app). Luckily, visa was approved before landing. Unnecessary stress created here. Food - main meal, curry chicken barely palatable with unrecognizable vegetable. Desert cup, cheesecake, also barely palatable. Salad cup was good. Small water offered only 3 times (before main meal, at main meal, at morning snack) - not nearly enough for long flight.

Boarding was not well coordinated. I asked twice at the Level check-in area about the MIA flight. At no point did they say the check-in would be at another counter. Fortunately, another passenger was equally confused and got the REAL story from the airport’s info center. Further, my minor child was tagged “SSSS” on their boarding pass. Level should have notified TSA about him being a minor. Instead, the entire family went through the SSSS process, not just our son. When his name was called out at the gate, it was announced in Spanish. No English announcement was made. The food on board was bearable. The crew was adequate, despite not being Level/Iberia crew (Level contracted out our flight to “World2Fly Airlines” - a company I have never heard of!). The onboard entertainment was very limited. They did not even offer a flight tracker option. Nor were music selections offered. Like TAP and Aer Lingus, I will think twice before booking Level ever again.

we had a flight confirmed then we were called and told we didn't have a flight. I will never use Kayak for a flight again.

From boarding, to attention in flight, I couldn’t fault it.

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.

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.

Flight was delayed. Though I checked in with BA live chat three times, our special meals were not provided.

My experience with British Airways is excellent, thanks for all 🫶🏻✈️

Our luggage arrived 2 days late when we reached Santorini. We were without cloths and toiletries for two days and didn't had time or means to go and shop everything at reasonable cost. Even though, we filed the report immediately at the airport, there was very less communication to us about when we would expected our luggage and even when it arrived there, they didn't had staff to deliver luggage to our hotel, so we had to go to airport to pick it up, which is very difficult and annoying to do in foreign country where you don't have you own vehicle and you don't have time because your tour is packed with activities. They could have tried to expedite the process and kept us informed and deliver the luggage at our hotel. Also, should have given us compensation for it.

Fair, difficult to find the departure gate. Luggage delayed on arrival

Very old aircraft. Seat 15 A & B personal light not working, foot rest broken in 15 A , reclining push buttons required two people to do it. Overall experience was below standard. The same food was served both the times. No snacks in the ally, drink choices very limited. It felt like it was the year 2000. The crew unfriendly, hospitality 4/10.

Friendly on board crew, kept informed on flight. Pre-ordered food arrived as ordered

The crew is very friendly and helpful. The food is good for airplane food. The flight is long and hard to sleep. The leg space is great. The plane arrived in plenty of time.

I would like to recognize a crewmember for her above and beyond service. Her name is Emily Milburn. The flight was delayed for more than a couple of hours, as we sat on the tarmac because of a storm in London. I could not connect to the Wi-Fi, which I needed to do to arrange for my follow up flight back to the US. This young lady told me that her cell phone had reception and offered to provide me connection through her phone. I was beyond impressed. Later on the gentleman sitting next to me, could not connect to the charging portal. Emily came back with her personal auxiliary battery and offered to the other passenger. She certainly needs to be recognized by British Airways for going above and beyond what is expected. She was the ultimate professional and very friendly, and I have to admit that, given the delay, the passengers were not the easiest to deal with.

Both the flight from/to San Diego and London went very well. There were lots of movies from which to choose for entertainment, the food was nice, and the flight departure and landing times were good to minimize jet lag.

They damaged my check in bag and when I filled complaint they gave some minimal amount which is not even sufficient to buy new bag. Vey unhappy with this experience.
