At JFK the Security line was extremely long and few checkpoints open.

Flight attendant -José? - was over the top friendly and professional. Beautiful new plane with lie flat seats in Business (worth it!)

Horrible food. No wine or any other alcohol is served on the flight. Water is not served often and they refused when I asked for water in two cups. On the other hand, both going and coming back flights were on time.

Great! The airline is very spacious and the crow was good.

Not being in the back row and having to pay for a better seat

On the trip to Rosario, we raw dogged it for 7 hours. No wifi, no charging outlets, Gilbert girls on every third row monitor with no audio. It was better on the return flight—at least we had screens and earplugs.

I would like a glass of wine or some kind of alcoholic drink.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

Everything was smooth and crew was very polite and friendly.

it was great! Boarded on-time, reasonable leg room, pleasant staff, decent food. The only thing is we were directed to Terminal 2 when the gate was actually in Terminal 1. Smooth ride. Landed early. Got off plane easily and quickly.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

Love the mosaic program, being able to move to an extra space seat for free is awesome

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.

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

Boarding was somewhat confusing in that the wrong messages were being displayed at the gate. It was somewhat annoying that I got off one flight and straight onto another (from the same gate), but in between they re-checked my hand luggage and made me get rid of my water (which they charge for on the plane). I was sitting in their 'Plus' seating, but the leg room was still too small to be able to sit square. The food options on the flights are pretty cheap quality (but not price). They got me from 'A' to 'B' on-time and for a relatively good price, but the experience itself was below average.

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

Be very careful of the initial low price because Avianca wil bill you for a carryon of $120 or a checked bag for $120. Also, be careful with connections because the customs entry process is slow and the connecting terminal is not close.

My whole return flight itinerary, 3 flights, got canceled without any warning to me because I missed one of the earlier flights 3 weeks ago

Horrible. I have been trying to speak to a representative to know why I was over charged but I get redirected to AI Vianca everytime with no results. Is there an agency that oversees airline gouging? I will never fly or recommend Avianca to anyone not that you care.

Felt very cramped in the back of plane. There was an hour delay for take off sitting on the runway, but we did arrive on time. They charge $120 for carry on bag and backpack at the airport its ridiculous.

Almost we lost our connection from Bogota to Aruba 🥴 Because we get out late from the plane of Medellin

Same experience, very poor food, drinks or entertainment while flying. There are some products offered to buy but only using debit or credit cards . No friendly for seniors or people without cards.

Avíanca now has cero entertainment, food and even water for their travels in economy. We spend all 6 or more hours ignored or we are offered products to buy using only credit card .

Flight was on time It was a good flight overall

Check in at dtw was understaffed and chaotic. Flight itself was smooth. Airplane seats seemed newly upholstered and comfortable, flight attendants attentive.

The plane flew smoothly and the crew was polite and kind. We loved our flight!

Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.

The senior flight attendant was engaging, funny and made everyone feel at ease. She is an asset to your team.

All was ok until my last flight, when I was stopped while boarding and they insisted they take my carry on bag and check it and charged me $99 to do so. This was my 4th flight and the carryon did not change, so I was shocked when they made me check it and proceeded to demand $99 to check it. I was furious. This airline advertises as cheap flights but they will attempt to charge extra for bags, seats, oxygen, whatever else they can find and no extras, you don’t even get water.

Terrible-extreme delay with very little communication, plane was overfull, luggage was returned on baggage claim in filthy condition.

Needs legroom for tall people. Needs to offer a glass of water.

Seats are very uncomfortable pls make your seats comfortable pls pls pls

They changed our departure time 6 times before I even reached the airport. Delayed, Ontime, Delayed Back on time, Then Delayed. We finally boarded the plane and then we had to sit on the runway for over an hour only to be told they were taking us back to the gate for an additional 2 hour delay. Lack of communication and a complete waste of time! Never again!
