Good check in process Poor information on payments at Lima airport

On board crew was very good. Crew was friendly, snacks were good, especially the chips. Seats seemed a bit cramped. Boarding seemed unorganized, as we were instructed to get to the gate an hour early and then just stood around until boarding.

We were not allowed to carry a bottle of water onto the 8 hour flight.

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

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 assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

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

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.

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

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

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

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

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral and avianca lost my check in luggage

I upgraded to businesses class. Because of that the flight was comfortable.

Provide free food and drinks on an international flight. Add updated head rests

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

Staff are the rudest in the industry … awful customer service … will never fly Avianca again

Pros: we leave and arrive on time Cons: the most uncomfortable seats ever. You cant recline at all your seats. No entertainment No TVs flight attendants didn't provide even a glass of water. You have to go to back of the airplane and ask for one. I am Colombian and I remember seeing the flight attendants very neat, elegants which is or was a staple of Avianca.it was one with tennis shoes, no male up, the hair was messy... that was really odd.

The flight attendant smashed her beverage cart into my knee, causing significant amount of pain. The seats were extremely uncomfortable. No food or drink is offered unless you want to pay the ridiculous prices for it. The schedule of flying in the overnight hours is also very uncomfortable.

We waited for one hour to deboard the plane after landing. That could be better

No free snacks nor drinks on very short 30min flight. Entertainment system is over wifi to your own phone or tablet, which is good but often a show or movie just stops and refuses to continue

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive
