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.

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

Poor, the airline was not able to help me move flights.

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 .

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

I’m entitled to a refund per LATAM due to the mid flight itinerary change and being stuck in São Paulo for 24 hours and needing to get a hotel. The airline was dismissive and of no help.

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

I was not able to get on the flight due to delays out of Philadelphia. I arrived in MIA at 10:30pm and there was no one at the GOL Desk. Is there any flight credit available for this flight?

I have a hand injury and the flight attendant denied to help me with luggage, she said "she couldn't help me because I should manage my own way to put the luggage on the plane" SO RUDE

I had two around 6 hours flight and they did not even offer water to us.

Overall it was good. The food was not great quality and seats were very uncomfortable. But overall the staff was very friendly and helpful.

We flew with Avianca, some how they are not n sync, making the process a bit uncomfortable.

Unfortunately it was very disappointed experience. Our first flight our was delayed 2 hours, as a consequence we missed our connecting international flight. Customer server at Miami American Airlines was very disrespectful, gave us the worst replace itenarary for the next day that we had to spend 2 hours calling Gol to get a better itinerary otherwise we wouldn't make it on time to fulfill our trip purpose. We would have missed the reason to travel all the way to Brazil if we didn't change for a better itinerary. The worst thing is that our baggage was missing for 4 days. We had no cloths for all this time, plus the aggravation to locate our baggage. Nobody knew where our baggage was. We ended up picking it up at the airport when they said that they will bring them home. Unfortunately our experience was very dissatisfied.

Flight on time, check in and flight attendants courteous and helpful. Smaller plane for international flights, tight space, no comfortable.

the boarding staff were incredibly officious. our carry-on case was borderline within dimensions but staff were not prepared to show ANY flexibility even though many others with larger carry-on luggage were allowed to board. we were understandably furious but the staff were incredibly disrespectful. we called the supervisor who eventually agreed to look on board the plane to see if there was room for our case (one case between 2 of us) and reluctantly agreed to allow us on. The staff on board were excellent though and realized we had been treated badly and were very helpful both in finding a place for our case, some distance from our seats, and helping us to retrieve it when we landed. We are regular travelers on Gol and have Diamante status and had chosen the better Conforto + seats, so we expected better treatment from the ground staff. Also the cabins are of a size that will only fit 3 cases of normal size with a large gap of about 30cm of wasted space. If our case were deemed to be oversize, which I dispute, the extra 1cm would not have made the slightest difference.

I did not like the way that baggage fees were charged. When I signed up for the flight, I knew that there were bag fees. However, the bag fees were so confusing that it felt like I was paying for overweight bags rather than just for having brought a bag with me. Also, the bag fees were based on the pair of tickets rather than per person. It seems to me that it should be first bag fee for passenger 1 and then first bag fee for passenger 2. I eventually got away with only paying $100 for two bags, but it was a struggle to understand the process. As for the flight, the seats were the standard uncomfortable seats that are on most Boeing aircraft. The airline aims to accommodate the standard height people, so us tall people are stuck. There was never an option to upgrade for leg room. It did not appear that there were any seats on the whole plane that had a little more leg room to even try to get. Other than that, I completely ignored the food for this red eye flight. I am not one to eat "dinner" at 2 am. They did not offer any drinks in the morning before landing. I recommend that you bring a bottle of water on board.

Lost luggage, people are not very nice to help you , I was just instructed to fill out a baggage claim online, they were not helpful when I had additional questions after I completed the form on my phone.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

I am not very tall, and had a difficult time getting my carry-on placed in the overhead bin while passengers were behind me waiting to get to their seats. After struggling with the luggage, I turned it around, and left it, knowing it was not properly placed, but believing there was adequate room for it in the bin. When the flight attendant came through the cabin, she asked whose bag it was, and scolded me for not positioning it correctly. She turned it around and moved on. I thought that her approach was totally unprofessional, calling out a passenger in that manner.

TAP‘s flight attendants seem to be among the least ambitious of all the international flight crews we’ve flown with. . When we left US and went to Portugal, and when we returned from Portugal, flight attendants were not very visible. Then did not offer frequent water breaks and when we had to go back to request water, I was almost an imposition. Meal quality was just average. The dinners were fine. Breakfast wraps were presented soggy.

There was no warning that they have added passport control after check in, the line was enormous and after 46 mins wait we missed our flight. Were forced to leave the airport and purchase new tickets at full price to board a later flight. TAP were unsympathetic and unhelpful.

Boarding we were jammed into a hot crowded bus waiting too long while another bus went in front of us. Appreciated blanket and pillow, movie available helped time pass, the food was not appealing so I had my own snacks, the flight is long, but nothing they can do about that. Staff adequate, flight good.

The business class seats were smaller and closer together than other airlines.

Didn't like much. Wheelchair assistance was almost nonexistent. No one at TAP check in process helpful. On the plane, stewards were not friendly and disorganized. Food was terrible for 8 hr flight. We were skipped at snack time and even though we tried to get attention using overhead call system no one even looked up at us to acknowledge. Being at the back of first section and by the lavatory we only were able to request when they came to pick up everyone else's garbage and they were nonchalant...no apology or even choice. The 1/2 half bread with slice of cheese was a waste. Deplaning was horrible but I'll blame lisbon airport for that. Plane left late at made good time still arrived about 15 behind schedule and for using remote deplaning and bus to terminal took another 20 min to gate. Those with connections were highly stressed. Took us 2 hrs from landing to get to ground transportation and exit airport. And that was with wheelchair assistance.

This flight arrived late. We joined well over a thousand of other people waiting to go through customs. Air Portugal has lost my bag. We had to chase down a representative even though we had waited at the baggage claim for well over 1 hour and 35 minutes for baggage to come. No representative was there to explain the delay or to give any direction. After 1 hour and 35 minutes at least four passengers had no baggage to pick up or had a fraction of their baggage. The representative was a young woman who clearly did not have the experience to deal with what was happening. Very disappointing as of course we were dealing with great amount of jet lag and having been up for 24 hours at that point and not being able to have any of the things necessary at home that were contained in the bag was quite upsetting. That instant occurred last night at approximately 11:15 p.m. and as of 12:30 p.m. the next day I have not heard anything from Air Portugal.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.
