Outstanding service both from ground staff and onboard staff! Very helpful in making changes to our schedule when our trip ended sooner then expected

They changed the flight and the airport on both legs of my flight which made it impossible to actually make the connection from one airport to the other in time. However the customer service agent at the international airport was very kind and helpful getting me on a flight for the next morning.

We were delightfully surprised with the exceptional ground staff as well as flight staff. Both did an excellent job of making our trip enjoyable and hassle free!

Please work on delays. This airline always has delays. The terminal is awful, aeroparque needs more transport for disabled people (terrible service), and proper equipment to deplane. It is the only place where I always have to use stairs

I flew in a new plane with an excellent crew.Felt great

My experience was TERRIBLE. They made me check my carry on bag, and they broke it. and then when I made the claim they said it was a small damage and that I would not be compensated.

Despite asking several times why our flight wasn’t on the boards, it took us a while to figure out that our departing flight was from another airport. While the tickets clearly indicated that we arrived at AEP and left from EZE, none of the aerolineas argentinas personnel noticed it despite specific questions from us. It took a sharp-eyed passport control person to notice it the second time I tried to go through security after exiting to try again to figure out what was going on. Also the what’s app is only in Spanish and when I tried to type Spanish from an English phone, it would mess up the Spanish that was already quite rudimentary

Delayed flights and cancelled flights …still waiting to see if the cancellations are refunded

The flight was 30 minutes delayed, but the boarding gate's panels indicated it was on time. This was inaccurate.

The staff was fine in the fly, but to do check in was very poor the service.

Some of the Air hostesses are not that friendly. Need improvement

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

horrible service, food was an embarrassment, no charging for cellphones, stay away

Great experience with a crew always thinking in the passenger

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

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.

Had to go through security at the gate again. Had to take off shoes and go through the whole thing again even though we have global entry. They asked us to check in items bought at duty free during our layover and since we checked our luggage at the original departure airport, they forced us to check in a small backpack. None of this ever happened with other airlines. In addition, no vegetarian food option and no snacks during a 7 hr flight. Luggage limits are unusually small. This is unacceptable. Will NEVER fly Copa again and will tell friends and family to avoid this airline.

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

The flight was late. Please do not delay next time.

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.

Because the flight was late, we lost the connection to Brazil. You, Delta delayed, and you Delta anticipated the door closing in 15 min from Miami to GRU. Why? It caused a lot of stress! I almost could not see my mother in law alive because of your delay.

My entertainment did not work. I was very tired from the botched connection, and the poor sleep

Lost ,y connection due to a mechanical delay, huge line to get new connection and vouchers
