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

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

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

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

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

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.

Very happy with my flight. I would definitely recommend it.

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

I have a hand injury and the flight attendant denied to help me with luggage, she said "she couldn't help me because I should manage my own way to put the luggage on the plane" SO RUDE

I had two around 6 hours flight and they did not even offer water to us.

Overall it was good. The food was not great quality and seats were very uncomfortable. But overall the staff was very friendly and helpful.

We flew with Avianca, some how they are not n sync, making the process a bit uncomfortable.

Unfortunately it was very disappointed experience. Our first flight our was delayed 2 hours, as a consequence we missed our connecting international flight. Customer server at Miami American Airlines was very disrespectful, gave us the worst replace itenarary for the next day that we had to spend 2 hours calling Gol to get a better itinerary otherwise we wouldn't make it on time to fulfill our trip purpose. We would have missed the reason to travel all the way to Brazil if we didn't change for a better itinerary. The worst thing is that our baggage was missing for 4 days. We had no cloths for all this time, plus the aggravation to locate our baggage. Nobody knew where our baggage was. We ended up picking it up at the airport when they said that they will bring them home. Unfortunately our experience was very dissatisfied.

Flight on time, check in and flight attendants courteous and helpful. Smaller plane for international flights, tight space, no comfortable.

the boarding staff were incredibly officious. our carry-on case was borderline within dimensions but staff were not prepared to show ANY flexibility even though many others with larger carry-on luggage were allowed to board. we were understandably furious but the staff were incredibly disrespectful. we called the supervisor who eventually agreed to look on board the plane to see if there was room for our case (one case between 2 of us) and reluctantly agreed to allow us on. The staff on board were excellent though and realized we had been treated badly and were very helpful both in finding a place for our case, some distance from our seats, and helping us to retrieve it when we landed. We are regular travelers on Gol and have Diamante status and had chosen the better Conforto + seats, so we expected better treatment from the ground staff. Also the cabins are of a size that will only fit 3 cases of normal size with a large gap of about 30cm of wasted space. If our case were deemed to be oversize, which I dispute, the extra 1cm would not have made the slightest difference.

I did not like the way that baggage fees were charged. When I signed up for the flight, I knew that there were bag fees. However, the bag fees were so confusing that it felt like I was paying for overweight bags rather than just for having brought a bag with me. Also, the bag fees were based on the pair of tickets rather than per person. It seems to me that it should be first bag fee for passenger 1 and then first bag fee for passenger 2. I eventually got away with only paying $100 for two bags, but it was a struggle to understand the process. As for the flight, the seats were the standard uncomfortable seats that are on most Boeing aircraft. The airline aims to accommodate the standard height people, so us tall people are stuck. There was never an option to upgrade for leg room. It did not appear that there were any seats on the whole plane that had a little more leg room to even try to get. Other than that, I completely ignored the food for this red eye flight. I am not one to eat "dinner" at 2 am. They did not offer any drinks in the morning before landing. I recommend that you bring a bottle of water on board.

Lost luggage, people are not very nice to help you , I was just instructed to fill out a baggage claim online, they were not helpful when I had additional questions after I completed the form on my phone.

They are not ready for international flights, poor service and food, no screen info on the seat.

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

Boarding, crew were excellent, food was ok and entertainment need to improve

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

No food, terms when selling are not clear. To pricy for the service in general

It was horrible. My experience with Avianca. I didn’t know it was Pakistan international Airlines but anyway, whatever it is it is bad horrible you guys need to upgrade everything in those planes. And you guys charge $130 for a carry-on did they wanna let me in with my carry-on that I travel everywhere with the luggage you guys are such a dog thank you

The incoming plane was late and no information was shared. They even announced we would board in 10 muntes 40 minutes prior to the plane arriving, and the website said until takeoff that we had taken off an hour earlier

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.

Seats are very tight even in Plus, no complimentary snacks or beverage

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.

I receive a service for what I pay, so it is fair.
