other than a slight delay in takeoff from Panama , the flights were excellent ..... we will continue to use Copa whenever possible for flights to and from Central and South America ....

10.0 ExcellentLeslie, Nov 2023PTY - YYZ

other than a slight delay in takeoff from Panama , the flights were excellent ..... we will continue to use Copa whenever possible for flights to and from Central and South America ....

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

Cons: "Copa is trash . Doesn’t accolade passengers with hotels . They except people to wait in the airport for 14 hrs lay over when it’s their fault ! Straight trash . Poor 79 year old lady had to stay at the airport cause her family was 4 hours away ! Trash trash"
Pros: "Nothing. This airline is awful in every way imaginable."
Cons: "We booked tickets to Costa Rica with Copa and they just changed our flights to two days later than the booking. They didn’t even bother to inform us of the change we only found out because we booked through Kayak and they let us know. Apparently Copa expects you to frequently check your booking just in case they’ve changed anything and don’t feel the need to inform their customers of any changes they make. Then we were told we could get a Copa voucher to use for other Copa flights for having to cancel our booking and rebook with another airline as a 48 hour change to our flight made flying with Copa not doable for us. But the website kept telling us we had a voucher that was sent to our email but despite repeated attempts it never came through. And spent hours trying to get through to someone on the phone to sort it out with no success ever getting through. My advice. NEVER EVER FLY WITH COPA."
Pros: "Both of my flights were on time which i know sounds basic but all of the flights i’ve catched from SJO to X were late and this time my connection in Panama was only 1h15 and we got there earlier, so that was nice!"
Cons: "A bunch of seats were free and we were mostly sat all together (3 person next to each other).. With the covid situation i think it could be good to be more separate if possible"
Pros: "Crew and i ohhh ver all copa experience."
Cons: "Nothing. I am now a loyal Copa flier. Any of my trips to Latin America I will consider flying with Copa"
Pros: "Crew was great. Supportive and friendly. Plane was clean and comfortable."
Pros: "The seat comfort and staff especially the captain - very engaging"
Cons: "WiFi on the airplane to access flight map and other services."
Pros: "good crew, food was okay."
Cons: "really uncomfortable seats, too small for an international flight. couldn't lean back because the guy behind me was tall, so my back was hurting the entire time."
Pros: "Food was good"
Cons: "Different movie, more leg room but I'm tall so that is with any plane."

I didn't realize they didn't have bathrooms on the plane. Almost had a very bad situation.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Not very good, they nickel & dime you for better seats & pay extra for the checking in bag, bad service all the way around

Flight was great Customer service was questionable until we found someone at checkin to help us. One young lady took all our passports disappeared for 15 minutes, came back with nothing done, handed to someone else and left for lunch. Very complacent. Baggage was very expensive until we went to the service counter and a separate person helped us. Even with platinum status they wouldn’t allow free bags. We will continue to fly Delta as our preferred carrier but will avoid checking in with Latam. Dr. Armand Radke

It was ok for the most part, it is missing something

Hostile flight attendants. Second flight with Jose so much better. Arrived 1/2 hour early. Thanks.

Liked check in process To improve: food and beverages. Not second round was offered and meal had no salad.

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

Tough flight with turbulence… I was told by a fellow passenger that it is common. Nonetheless, very stressful. Cordial staff.

Check in of my luggage which needed to be paid for was excellent. Thanks to Nora

GOL made the flight experience a true delight. Everything was smooth, from the check in process, to the disembarking moment.

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.

They could offer free food and drink like other international flights.

They could offer food and drink without having to pay extra for it,

Delay almost an hour which meant when we got to Guatemala there where 3 flights at the same time, you can imagine the caos in customs, avianca doesn’t care about passengers or schedules

Avianca: you pay for a high-end flight and you fly like a low (very low) cost!

They charge me $190.00 dollars for the baggage for the bag in side the plane and in the baggage compartment in the plane. The service I got bad bad bad they make wait for a log time and i got to the airport 4 hours before. I don't think I'm going to use you guys never never again no support . And I am going to tell all the guys and people i now to don' use KAYAK

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.

50% of flights book with Avanca have issues either reschedualed cancelled and their actions further supports their poorly managed airline do not use them only if there is no other options

The only thing I like about Avianca is that it is the airline of last choice and they never disappoint my expectations

I paid extra for a comfortable seat in the second flight, but the plane didn't have those seats, the first one did

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.

My seat was broken and the crew had to find me somewhere else to sit. The crew was extremely courteous about this
