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.

It’s been some time since I saw the plane and the cabin that old and worn out.

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

I loved how polite the crew was even though some of them wasn't the best with English that they still done everything they could to help me with my needs food was amazing

Terrible They charged me 157$ for excess baggage even though my bags were within the normally accepted limits Flight was late. Service was poor. The snacks were really bad

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

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

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.

I don't think anyone actually reads these comments, so I won't spend much time on this submission. If you want to talk, you know how to reach me. The D/FW manager of Avianca (self-identified), Juan Calderon, insisted I buy an onward ticket from San Salvador even though I have diplomatic status in El Salvador and live here. It cost me $1,393 and Mr Calderon would not let me make the ticked flexible so I could get a refund. He went out of his way to be rude to me. He gave me seat 32K -- windowless window seat in the last row and did not offer to let me upgrade even though there were plenty of seats. I have flown well over a million miles in my life and this is the worst experience I have ever had. I would like a refund on the ticket I was forced to buy. Just awful!

This is the Spirit of Latino travel. And don’t even get me started on customer service.

Awful. I checked in online and there was no option to pay for baggage, at the airport when I checked in my baggage was received and Iwas not charged. When I got to LA during the boarding process I was told I didn't pay for baggage, the crew resolved I was let in the plane. When I got to my final destination my baggage was not there. It took me two days to receive my baggage. Bad service ever!

There was no food or drink service, couldn’t even get a glass of water for free. It was a long and expensive flight to not offer food or beverage on the plane.

It is better at the jfk than my home country. It was very easy and everything was on time.

There is no food. There is no in-inflight entertainment. The seats are cardboard. The airline is a living hellscape.

My experience was amazing! They helped my elderly mother board on early through a wheelchair and were accommodating to have us sit together since our seats were in different locations. When landing at the airport in GUA they were very helpful with full of hospitality.

No complimentary snacks food, beverage (not even water), pillow and blanket on a 6 hours long flight (including economy comfort). A low form of nickeling an diming. Lost a recurring passanger over a soda. Avianca never again.

Flight departure late. Got late in Colombia making us take a different flight next day. Avianca airport crew messed up my ticket so when a I got in Brazil I didn’t have a ticket for my destination. Had to buy a new ticket out of my pocket.

They charge me $190.00 dollars for the baggage for the bag in side the plane and in the baggage compartment in the plane. The service I got bad bad bad they make wait for a log time and i got to the airport 4 hours before. I don't think I'm going to use you guys never never again no support . And I am going to tell all the guys and people i now to don' use KAYAK

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.

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!!
