Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

I didn’t not like that I could not select my seat and ended up with the worse seat.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

Please see my lengthy description on MSP to Atlanta survey. Tailbone is killing me from old hard seats. Seat would not recline and were not near exit row. Entertainment did not work properly and couldn’t use. No audio and touch screen failed. 3 plus hours of discomfort in narrower seats than previous flight not in comfort plus. Very dissatisfied and deserve comfort plus charges refunds, at the very least, for both my wife and I. The plane needs to be retired. Please feel free to contact me directly for further details.

MSP to Atlanta was much better than Atlanta to St. Kitts. Paid $180 each for myself and wife for Delta comfort from Atlanta to St. Kitts. Seats were more narrow and obviously old and worn out. Tailbone is killing me. Seat would not recline. Seats behind reclined and we were not an exit row or in front of an exit row. Entertainment did not work in that the movie jumped forward and back and there was no audio. The plug in the arm rest was loose. Flight attendant tried “resetting” the video for my seat but no good. She never checked back. Someone else near me had the same issue. Touch screen was unresponsive. No where near as comfortable as MSP to Atlanta flight. 3 plus hrs. flight time without the basic amenities and not even remotely close to comfortable but paid for Comfort plus. I will be very disappointed if I have the same on my return “Comfort Plus” flight St. Kitts to Atlanta. At the very least my wife and I should be refunded for round trip “Comfort Plus” charges. Please feel free to contact me directly for more details.

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."

Everything was as you would expect in coach - fine. Flight was close to on time.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Horrific checkin procedure with neither Delta nor Latam figuring out how to check me in. 4 hrs on customer support with both and both airlines pointing to each other who should do checking. I was not checked in until morning of flight, which for international flight is concerning.

It was a good experience, the flight was a little too long & the food was ok

Liked check in process To improve: food and beverages. Not second round was offered and meal had no salad.

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

Tough flight with turbulence… I was told by a fellow passenger that it is common. Nonetheless, very stressful. Cordial staff.

Very unprofessional staff in the checking and boarding. There was no space for my carry-on bag, which is understandable for a full flight. However, the rudeness in answering my questions about my bag were unnecessary. Shaming and threatening a passenger to be left behind was something I had never experienced (I am 57 years old and a Skymiles member) before. At a minimum, the boarding staff (Krystal Mejia and her manager Dee) should undergo further training on cultural sensitivity and professional skills on speaking with passengers. Krystal, just because I have dark hair and “look Latina” does not mean I can speak Spanish. Your assumption and threatening words until the very ending of my boarding (door of the airplane) were not only unnecessary and stressful but something that a passenger should not experience before boarding.

As usual, LATAM tried to rip me off as a Gringo. They ignored the fact that having paid for my assigned seats, I was entitled to one free luggage per person, up to 10kg, and tried to charge me USD40 per item. While they ripped me off by $160 on my outbound flight (4 luggage pieces, which should have been free), I vehemently protested this time around. Note that they only request this from gringos, not from Spanish speakers. LATAM behaves like a racist extortion organization.

The flight from PDX to New York was cancelled, and I got rebooked one day later. Because of this I missed a meeting at my final destination, EZE. I now need to stay longer in Argentina, and was told the tariff difference was $780 plus $150 penalty! I am not using my return ticket, and have purchased a one way ticket EZE-PDX for $606 with another airline. SHAMEFUL

Flight delayed for 2 hours due to a part. The plane sat waiting for boarding for a long time and during final preflight inspection the issue was found. Why not do the preflight inspection sooner if you know the plane is being used?

The flight experience was very good! Especially the United Club!

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

the head jack on my seat didn't work and the power outlet didn't work for my seat

All good except paid for wifi that did not work

Beverage and food services are excellent. We enjoy paying the extra for economy plus for the 3 inches more leg room to be exact.

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

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

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

Flight was good and arrived a little early. Very good.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.

When we exited the plane our wheelchair wasn’t there. The Pilot and co pilot were so nice and helped us locate it. Great service.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Same basket of unhealthy prepackaged snacks (junk food) which was depleted by the time it got to my row!!

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
