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 Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

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

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.

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

There was no individual at the front check in when I arrived. I waited for at least 15 minutes and walked around asking security/janitors if they could help and they did not have a solution. So I had to take my checked bag through security and they threw away some of my items. I ended up making it to the gate only a few minutes before it closed due to my waiting for an agent at check in.

The plane doesn’t have screens but you can use your decide for entertainment. Pack a snack too since they don’t offer any, and the meal is pretty small and you will get hungry

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.

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

Very friendly staff. The flight was on time. Need a bit heavy covers/blankets. It can get colder with a thin blanket.

Brutal delay of 24 hours on first floight the 3 hours in Chicago . Tiny seats , screaming child behind me kicking the seat … couldn’t be worse

Boarding was late due to the company’s that cleaned the aircraft (very poorly done) and the catering company. The entertainment system was not working for this six hour flight, uncomfortable seats in business (barely any cushion or recline). The airline staff is very good but the planes are horrible and not well maintained.

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

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

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

They charged me $120 to check one bag and then charged me another $120 for a carryon. Ridiculous!

No comfort at all. You should add at least 1 meal or a bottle of water. I wanted to buy one sandwich and everything was gone.

Discomfort has become a feature in Avianca flights. That isn’t terrible on short, local flights (most of them 1-2 Hrs)… but a 7-Hr flight with no water, no coffeee, no nothing (unless you buy it) is just not right. Uncomfortable seats, almost inhuman space between chairs, in long-haul flights needs to be reviewed by airline. And unavailable entertainment system doesn’t help either. Flight was safe and on-time, which isn’t easy to achieve. But all other features aren’t features: they’re a modern way of torture. Avianca really needs to up their game, or bluntly declare: we’re an ultra low-cost airline, and fees will drop accordingly.

No complimentary snacks, food, beverages (even water) blanket and pillow on a 6 hours long flight (economy comfort). A low form of nickeling and diming. Lost a recurring pessanger over a soda. Will never fly Avianca again.

Flight departure late. Got late in Colombia making us take a different flight next day. Avianca airport crew messed up my ticket so when a I got in Brazil I didn’t have a ticket for my destination. Had to buy a new ticket out of my pocket.

The flight was overbooked and the solution gave was unrespctful. I arrived 4 hour in advance in the airport and only after 2hous was possible suggest a different ticket with another company LATAM, I have accepted, but when I was checking in at LATAM the tickets was issued without luggage, what it is absurd since I have bought my tickets including it since the beginning. Due to the timing for the next flight was not possible return to Avianca to claim due to the distance between Both companies Avianca and Latam since were located in different terminals. I have insiste to the crew of Latam to call Avianca to solve it, but they could help they were alleging that only paying a thousand pesos Mexicans ($1,000 MXN) to dispatch my luggage would be accepted and I have no money at all. So I had to beg for others passagens, it was an humiliating to exchange luggage with who was platinum in order to return back the luggage in the connection airport in Brazil (GRU). I have no clue that a judicial process would be taken from my side due the lots of stress in sequence by the non professional treatment with a passenger that was just following everything said by Avianca.. Long hours of waiting until next flight and only arrive at final destine in 6hs later..
