We were made to check our carry-on luggage because it did not fit the measurements. That’s what we were told, but I saw plenty of carry-on luggage on the plane that was the same size as ours

Flight Crew Review The crew was absolutely amazing from start to finish! They were friendly, professional, attentive, and genuinely made the flight feel comfortable and enjoyable. Every interaction was pleasant, and they went above and beyond to make sure passengers were taken care of. You could really tell that they cared about providing great service. I truly appreciate their kindness and professionalism and would be happy to fly with this crew again!

stood in line to check in luggage for nearly an hour. very poor service and not excusable

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

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

Very long delay but we just made the connection. The requested wheel chairs were not there so I had to assist/carry BOTH of my parents to the gate while carrying their bags so we could make the connection. The plane had no entertainment system and NO WIFI, legroom zero. Restrooms on ALL of flights were dirty and one restroom did not even work properly. I was surprised to see COPA like this since my flight with them in 2013 was incredible, the seats were amazing and the food options were spectacular. Of course, I see this kind of service on many airlines now, with services and hospitality at an all time low. The worse part of the trip was seeing my 90 year old parents go through hell on these flights and having to try and rush to a gate to make the next flight. Never again

Very good, despite we had a delay because of some problems at the airport.

All good. Easy check in and boarding. Lovely flight crew

WiFi broken, very long wait for valet bags, and the typical long wait at O'Hare on a thursday to get clearance to take off and then again long taxi and wait for the gate.

Another American flight, another significant non weather related delay. Was delayed over 90 minutes on both legs of the round trip.

The now boarding notification was not updated in the app until I was actually on the plan. This si a massive fail considering my flight was delayed several times. These types of failures add stress that could be avoided since I no longer feel comfortable leaving the boarding area to get food or visit a lounge. Had I used the notification from the app, I would have missed my flight. The secondly, the process of connecting to wifi on aa flights is clunky and could be streamlined better. the copy and past process feels like MVP, and you are well beyond that stage.

Both flights were late leaving due to repairs/switching gates. The crew and pilots, however, were professional and courteous. Most importantly, we arrived at our destination safely. The seats were comforable. That size should be standard for all economy class. American could improve its boarding process. I am not sure why you need 9 groups for a small regional plane.

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

Flight from Miami to Tampa was canceled on sudden notice. No alternatives were offered except next day's flight in the evening.

I arrived three hours early and I got all the way to the gate within 30 minutes once the ticket counter opened up. New trainee on her second day did a fabulous job.

A disaster, I lost my connection due to overcrowding at the Miami airport, having a 3-hour layover and the airline did nothing to reboard me on time and I had to sleep on the floor for 18 hours.

It’s a new plane, but the most important detail is that the economy class seat doesn't recline—it’s completely fixed. The only one that reclines is in Comfort Class.

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.

No free snacks nor drinks on very short 30min flight. Entertainment system is over wifi to your own phone or tablet, which is good but often a show or movie just stops and refuses to continue

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

i think the flight was late because they were so strict about measuring everyone's personal items to try and charge them $119. It was really petty and made us late.

So so, you feel like you have to pay for everything each time

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

Fly was cancel on the las minute wiht out tell me

Avianca: you pay for a high-end flight and you fly like a low (very low) cost!
