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

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

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

It was ok. However, the food was quite poor since I don't eat pasta.

Enforce the boarding process by group numbers. Tell people to stay seated during the meal/drink distribution. It took forever to get food and drinks because people would not stay out the isle and let the crew do their jobs. Everyone wanted to go to the bathroom forcing the crew to enter and leave the isle constantly so people can pass. Tell people to keep their electronics off speaker mode. No one wants to hear phone conversations and music playing.

Placed us in the last rear row of the plane so could not recline seats because of the rear wall, and also made it more of a tight space when the passenger in front reclined their seat. While understand seat assignments, every passenger should be afforded a reclining seat. The odor control scent from the restrooms was overwhelming strong. My wife and I could not deal with it, and she suffered a terrible headache as a result. I kept getting hit by the crew since I was on the ilse seat. No apologies, nothing. They made me feel like I was supposed to take the beating for a 3 hr flight.

There was no individual at the front check in when I arrived. I waited for at least 15 minutes and walked around asking security/janitors if they could help and they did not have a solution. So I had to take my checked bag through security and they threw away some of my items. I ended up making it to the gate only a few minutes before it closed due to my waiting for an agent at check in.

My flight delayed and i misss the connection they send me to orlando no to tampa i have to pay a uber to my house

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.

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.

Horrible the worst airlines I have ever flown. Cancelled flight with no choices and when contacted them they were not helpful

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.

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

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.

It was a very good flight, no entertainment is the reason for not checking that box.

I was in the last row and they sent me to check in my luggage last minute after boarding. I had to go through the crowd.

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.

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.

We fly American Airlines quite a bit. And we always fly business class when traveling internationally. We were a bit disappointed with the comfort of this particular plane as well as the entertainment options.

The AA staff person who checked our bags was curt and almost rude. The FA also seemed unhappy doing her job. Overall it was like riding the school bus back in grade school.

They are still charging me after taking 466 and 833 for round trip from AR to to Bradley airport from 19 to 21. Then poor experience. Am hurt and I will say it on social media. Please stay away from this airline. I see in my bank account they are still taking 644. Am trying to stop it. I used to fly United airlines and I suggest that if you don't want extra charges and good service you go back there. American airlines delayed my flight again and I was late for my meeting, no recompensation but charging me over and over.

Boarding, crew were excellent, food was ok and entertainment need to improve

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.

Seats are very tight even in Plus, no complimentary snacks or beverage

I receive a service for what I pay, so it is fair.

Purchased a business class ticket and got a economy seat with center seat blocked they call it business. 3100usd ticket on a flight where economy costs 500usd The biggest scam insult have had on a regular airline. Avianca should be in the low cost category and kicked out of Star Alliance. I want the difference to be credited. Ets see what Avianca does. No reply so far. Avianca = low cost airline. Beware

There isn't much space in-between seats and even water needs to be paid for during the flight.

We did not know about the bag fees until check in. They are way too high. It’s insane. We also had a huge delay and everything costed extra which was very annoying.

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.

Flew with our two children. Paid $380 to check two bags (one was overweight). They then left the bags behind on Sunday, December 21st, with all our family’s clothes and family Christmas presents. When we arrived at our destination they told us the bags had not arrived, and they thought (but didn’t know) they were still in Boston, but that there’d be a flight the next day and the bags would arrive the next day. The next day we found out there was no flight, now we’re hoping we get our bags before we fly back out. Meanwhile, trying to get any engagement or accurate information is a waste of time. The folks at the call center are just gatekeepers, who can’t connect with any departments that actually do things to solve a problem. Getting information is made deliberately difficult. My biggest regret is that I’ve had a number of awful experiences with Avianca traveling between the US and Colombia, and still let myself get suckered into buying these tickets because the schedule was great. Never again.
