The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

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.

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

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

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.

I never got this flight. You sent me to Chile!!! And from Chile I got the other flight to São Paulo... I've arrived 7h latter than I was supposed to arrive because of Delta delays.

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.

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

Boarding was done by woman who insisted on strict standing in line policy; food was ok; entertainment minimal

Terrible. They wouldn't allow me on my flight on the 14th..

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

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.

They are not ready for international flights, poor service and food, no screen info on the seat.

Horrible. I was never able to board the e flight as they had a glitch in their system that didn’t showed me as a passenger. I waited 2 hours at the front desk till they closed the flight, and they were not able to board me in it. They didn’t offer any sort of solution or refund. Such a disappointment. I would never flight with them again.

It was really bad. Inexperienced and rude people during check-in in Miami, a small and uncomfortable airplane, and problems with the airline caused me to lose my connection flight in Brasilia. Terrible experience!

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

Having to reschedule flights a day later, they loaded by luggage on the wrong plane from Little rock now I have to HOPE they deliver it to where im staying like they said would. International flight crew was very disgruntled and not very friendly.

We will be writing a long, detailed letter to corporate about our awful experience with American airlines.

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

The entertainment package was vast and the selections were very current. Keep updating it was great.
