Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Left my bags in origin city on a business class ticket , spent about 2-3 days in the same clothes plus the flight .

the planes are not modern there are no phone chargers

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

Pros: "The seats in economy were confortable. The best thing was Copa gave us seats in the second line and my family traveled together."
Cons: "Coffe service could better the experience"
Pros: "The crew was very interested on help and attentive with the passengers. But the seat wasn't comfortable. The design of the cushion is not the best to be seating"
Pros: "You were on time, that is the most important thing in a fly"
Cons: "You could improve your entertainment, you are not a cheap company"
Pros: "That there was seltzer"
Cons: "The management of preparing the flight and plane so that it was ready for the trip!!"
Pros: "Copa was convenient and easy. Very easy boarding process and I appreciated the day flight."
Cons: "This is a business class that is equivalent to a US carrier domestic first class. Good seats, not lay flat but wide on my 737-800. The food and service emulated say American Airlines Domestic 1C as well. Everything was just good enough, and much cheaper that international business on the majors."

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Food was terrible Not many options Stewards dont care Delay

The ride was good but no food ot entertainment hence, it was just over an hour flight.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.

Wasn’t very crowded. Seamless processes. No issues traveling with two little kids.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case

It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.
