We where skipped for this flight will not head to Panama until tonight..

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

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

Did upgrade, travel in business it was great (more room I could sleep)

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

I would enjoy a glass of wine on such a long flight.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

I was supposed to have a lay flat seat but they switched planes and there was only a chair

I liked the friendliness of the crew and comfortable flight. All good.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

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.

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

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

Plane never left the ground. Mech issues - entire trip was rerouted through united.

4 hours delay, awful food and missed all my connections because of the delay to be rebooks for a flight 10 hrs later back home and never actually make it to my final destination

I missed my plane because there was a lot of people during the migration process. The airline has the chance to care for their clients and they could get the passengers missing in the flight. I lost a day of work and Montfort transportation to go back home and go to the airport again. Unfortunately the airline doesn’t care about that. I use latam at least 4 times a year, so I guess I need to be treat better. In addition, one on my baggages didyarricw to my destination. So frustrated with this trip.

Flight from Lima to São Paulo didn’t have USB plug to charge the cellphone.

Our yoga retreat was cancelled and besides not refunding is, they would not even let us change dates or locations. As a matter of fact they wouldn’t even talk to us and kept referring to the travel agent, who said they couldn’t change anything and it was up to the airline to do so. They passed the buck until it was too late to do anything about it. Avoid Latham and Budget Air for your travel plans.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!

I really enjoyed the delicious food and the delicious breakfast; I also liked the seat—it was very comfortable—and the service was absolutely wonderful. The trip was smooth.

The food was awful. It had more than 2 hours delay. It was too expensive

They are offering less and less for more and more. They changed our seat that we paid extra to select at the last minute. The seats are way too narrow and my elbows went numb.

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

Cancelled flight, had to rearrange plans independently and no vouchers offered

lack of older, great films. Too many child-oriented films. Calculate your % of children passengers, which will be minor.

Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

Even though I we were flying Business, my wife was in a wheelchair and the lady in the counter told the airport employee that he had to make the line (this was a first for us). There was only snacks and a heavier option to sell. The staff in the plane was great.

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

The crew was great! They waited for me as Air Canada flight was delayed by 1:15 hours from Ottawa to Toronto. I am a bit disappointed that we could only use wifi for entertainment but I survived! The only thing I would of liked is a more comfortable seat. The seat cushions are not thick enough for flights longer than 3 hours. Aside from that, everything was great.

I like the crew they're very friendly. I don't like. on five hour flight they not offered snacks. Any drink. Not even coffee

Flight to Bogotá delayed by 3 h Missed connection from Bogotá to Guayaquil. Avianca unable to bring us to Baltra on time Overall delay 36h. We missed boat departure from galagos. Overall 10 day trip needed to be cancelled. Avianca was completely un-professional.

The seats were very uncomfortable. I would have upgrade or got different flight if I knew. I usually sleep in the plane but I couldn’t sleep at all. Very uncomfortable. Also no food or drink everything was to purchase, and that’s u usual for international flight.

They charged for WATER on a SIX hour flight!! never again!

Seat space was terrible no food on a six hour flight

The temperature was cold and the food that we had to pay for was awful. The crew didn’t even offer a free glass of water. It was a long, expensive and uncomfortable flight.

My international flight from LAX to Argentina had one free check in bag included in the price I paid, however your crew in LAX made me pay $95 USD to carry it on! Please note I had only on small size luggage (carry on size) and one backpack. I demand my $95 USD back that you guys charged me illegally in LAX.
