A lot things happened in this trip.The fly should be less stress.

Horrible. No TV or any type of entertainment on board. Passwnger listening to/watching stuff on their own phone with no headphones making it noise and uncomfortable for everyone else, little/tiny food portions, old seats, useless wifi (cant access anything). Horrible exlerience especially it was a lomg distance flight with kids.

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

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

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

the food served was an embarrassment. No connection for charging the cellphone... What a crappy airline.

Great experience with a crew always thinking in the passenger

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.

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

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

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Poor, the airline was not able to help me move flights.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

we were missing our luggage, trying to find someone to have any empathy was pretty much not happening....

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

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU
