Requested an aisle seat at the gate and got it. The staff so friendly

My experience was very good. Everything was excellent except for the food. The food was mediocre. Not alot of options and the flavor was okay.

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was very warm the entire time, despite my vents being open. Additionally, we didn't have internet on our personal devices

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

+1hr delay, asked the crew about my connection, to exit first or something and nothing was offered. Missed it.

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

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 selected first class expecting excetional service. It was mediocre at best. The food service was cold, meal choices was poor and on one leg they did provide dessert. I did enjoy the lay day seat but the movies were old and nothing current. Boarding the plane is always hot. So boarding is quite warm until your in the air. I took a small personal air fan. Update the meals and movies.

It was reasonably comfortable trip considering its duration (7 hours). Crew was very good and friendly, seats very more comfortable than other planes. Only negative comment would be that the bathroom light did not get its full brightness 🙃

Great from check in all the way to the end. Very happy with Copa

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

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.

The staff and flight were great! The inflight enteretaintment did not work from EZE to MIA. They attempted to troubleshoot but exhausted all options.

Poor... food was horrible, boarding very slow, service on board mediocre

Crew was rude, almost 6 hour flight after horrific customs re entry line and near flight miss (unable to bug airport food) without food offerings.

The service could have been better and the food was bad

Muy puntual para la salida y la llegada, personal abordo correcto, la comida regular sobre todo el desayuno triste

This was a very good flight. The seats on the Dreamliner were comfortable and all the outlets were functional. The crew was friendly and helpful. Boarding was fairly efficient, although it was delayed by a baffling search of all the hand luggage for liquids. The timing of this flight, leaving at 10:30 PM, was excellent. It was a good time to arrive at DFW also, as there was almost no delay in going through customs and immigration. I'd fly this route, at this time, on this airline again without complaint.

Delayed fly, employees at the counter not professional and lack empathy to help, crew inside the plane very rude and unfriendly my fly was delayed for 2 hours. For being this the first time I will say if there is not other option then I will fly with this airline. One more thing, the pilot never said a wakes the whole fly but until we are about to descend. Not a welcome message the wether at the destination and time to arrival. It seems that the airplane was flying by itself without pilots. Terrible.

I got to the airport and the airline told me i did not have a flight. I never got a confirmation email yet I did get charged. Please refund my money asap

Do not book with this airline. Flights delayed over 3 hours and no explanation. They keep changing your itinerary every hour.

Awful. Not water, or chargers or space under the seats, the plane was very old and poor maintenance, seats really dirty, sticky, seats pockets with wires pinching your knees. Connection with no announcements, plane departed 1.30 hour earlier for an extra stop to refueling in Trinidad & Tobago. Even that we had a 3 hrs delay, seated in the plane in the runway.

Really bad. Uncommunicated stop in Trinidad & Tobago for refueling. Extra stop added 3 hours of discomfort without allowing off the seat. Not even water, or chargers or boarding groups.

Staff were unfriendly and rude. Was stuck on runway for 2 hours after arrival in Boston.

We waited in an overcrowded bus for over a half hour. It was uncomfortable. It would have been better to have waited in the terminal in a line

The food for sale on board has opportunity for improvement.

I paid extra for a comfortable seat in the second flight, but the plane didn't have those seats, the first one did

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.
