Boarding was confusing from staff telling going to preboard and than to group 1 Airplane was not cooling at the beginning

Friendly crew, good food options, food not the best and seats not as comfy but that’s typical.

Do not book it’s a scam! They stole $1200 from me

Copa staff at PTY and one particular crew member were unhelpful & rude.

Seats were awful. Media should have been included for such a long flight.

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.

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.

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

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.

LATAM’s crews are fine, but God help you if you need any customer service. Their app and website never work, with error after error. Trying to solve anything over the phone is painful, and lastly, the boarding pass LATAM gave me to board the flight with Delta was invalid and I had to purchase an emergency one-way ticket at the last minute to get home.

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.

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

Overall, the flight went well and the service was good. However, there was a very frightening moment during landing in Bogotá. Just as the plane was about to touch down, it suddenly went back up into the air. The aircraft was not descending straight and seemed to move left and right, which made the situation feel unstable. This was quite scary. After going back up, the plane circled for about 15 minutes before attempting to land again. Although I understand that safety always comes first and situations like this can happen, it was still a shocking experience for passengers.

The worst experience I've ever had because the "people" @ Avianca wouldn't let me fly because they said I needed a round trip ticket

I had bad experiences before now was excellent I am glad they have business class again

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

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.

Here we have another airline flying to Guatemala but doesn't have a plus or a less, just in the middle. Why? Well, first we don't have even free water Movie selection is poor Seats don't recline in some places Food selection is carb based Forgot to mention, customer service on the web is the worst. Good things; Very reliable on schedule Kind crew

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

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
