On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

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."

Not enough legroom on flight. I was never offered the option of purchasing a seat with more legroom.

I had an 9 hr layover continuing on to Ushuaia. I expected to have to get my luggage & do customs but I did not expect Aerolinas Argentinas to make me sit with all of my luggage for 7 hours in the entrance part of the airport before they would let us re-check our bags & get back in where there are seats. People were sitting on the floor everywhere.

This is the worst airline I have used in my 30 years of travel. The boarding process was an absolute nightmare with endless lines. It took 4 hrs to get to gate while in Bunoes Aires. Also, they change flight times and gates several times leading us to go to multiple gates. Never will fly this airline again

Aerilineas changed my airport from aero parque to Ezeiza and didn’t take care of my transport. Seats were mediocre and ground personal weren’t very helpful. Too bad that’s the only option to fly to El calafate. Bad service, bad company

Better snacks options for a 3.25 hour flight . There was only 1 choice - a fruit granola bar .

I liked the airport and aircraft crew. I disliked the fact that I and TSA pre check approved but this airline is not affiliated to the program. I was 4 hours befor departure and I barely made it to the gate. The airline does not allow to buy extra luggage online. After waiting 1 hour and 45 minutes to check in my luggage I had to do another line to pay my luggage with another hour of waiting. Only one airline person to process payment. This is ridiculous and I saw so many elderly people struggling in line waiting long hours.

everything, disorganized, the flight was delayed an hour and twenty minutes without any explanation

Solo diré que mi vuelo tuvo 5 horas y media de atraso. Jamás explicaron el motivo y se tomaban el tiempo del mundo para anunciar su siguiente retraso. Es más, esperaban a que llegara la hora de la supuesta salida para decir que se retrasaba nuevamente por otra siguiente hora. Implicó que tuvimos que pagar gastos extrae por el alquiler de nuestro auto y cuando le planteamos a customer services se desentendieron totalmente. Nada profesionales novel dios. Tengo tanto que decir en contra de aerolíneas argentinas que prefiero parar acá. Terrible, terrible, terrible

Boarding was efficient and painless. Food was not supplied. It will be good if some chips or biscuits can be provided.

no usb conector. i freeze out all the flight, 2 blankets were not enough, apparently air conditioning cannot be tune. a seat side of mine has to be move because water falls from the upper luggage compartment

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

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.

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

Pros: "Nothing as we could not take the flight."
Cons: "Allowing the option to change your ticket date, but failing all debit and credit cards payments offered, actually means that they are not allowing flight changes due to COVID related issues like they say they do. We had to book new tickets with another airline to get home."
Pros: "The seat was comfort, good attention, flight on timing 😇"
Cons: "In several times the plane went down and up, and I think the pilot had no experience or it was the first time flying"

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

I think the seats on some of their planes are uncomfortable. You can be ok on a short flight of two hours but no more than that. The delays, and also the refreshments on the plane were not enough.

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children
