The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

Boarding was confusing with a delayed flight because there was no English translation

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

Horrible the worst airlines I have ever flown. Cancelled flight with no choices and when contacted them they were not helpful

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.

It’s a delta flight operated by LATAM. The whole ticket sale is a mess, delta changed my flight but didn’t update it in LATAM system, I couldn’t get my boarding pass, it took me hours to resolve this issue with delta. I had to change my travel plan. No apology from Delta even though it’s their fault.

entertainment was not good; the shoulder strap on Business class seat did not sit well across the body (more like across the neck); the food was not hot and the special meal promoted by insert in the menu was not available to us

It was a very good flight, no entertainment is the reason for not checking that box.

I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

A good, comfortable flight with friendly crew and good entertainment options.

Very rude person at the boarding desk; flight attendant coughing 3 inches from my face three times- not even covering her mouth; boarding process very unacceptable for older people with stairs to all planes (are you all stuck in the 1960’s?). I am sure that I am not remembering all of the negative things, but I am sure you get the message!

Flight was fine. Second meal ( fish sandwich on hard roll) was awful. My suitcase didn’t make the flight. It had been located, but won’t be delivered until tomorrow. Five days after flight

Boarding experience was awful. TAP claims I did not have check in luggage with tickets. I went 3-4 check in agents until I finally found a helpful kind agent who checked in my luggage with no fees. On top of that our flight was over 2 hours delayed with barely an apology or explanation.

boarding is so disorganized, i was literally appalled at the boarding experience

Was the best airplane ✈️ ever that I never see I will traveling again again with u guys.

Tap air Portugal was the best I will traveling again with u guys. Thank u.

Flight was delayed on 6/20 to miss international connection. Next flight out was 24 hours later. Not acceptable.

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

Need to pay for headsets, water, or any extra except air to breath.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

Sitting space was very tight, so eating was difficult. But everything else was good.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Need to pay for a cup of water. No food. Need to pay for headsets.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

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

The usb plugs for charging your phone didn’t work, the seats were coarse and hard. Not very comfortable. No inflight WiFi

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.

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

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

Avianca is not what it used to be. So disappointing

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

why did we have to go through security mid flight

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.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

The flight was fine but no food available apart from snacks like Pringles and olives which was a problem for me as I hadn’t eaten anything that day. But the worst problem was BA left 24 suitcases in Heathrow as the flight was too full but didn’t tell anyone. So we waited for ages at Toulouse airport with no information and finally found out from the one member of staff in the baggage collection area who explained what had happened and apologised for no announcement being made but said that was their policy. Then BA contacted me today to say they have found my luggage and can deliver it to me on Tuesday - half way through my holiday!!!! So a friend has had to make a four hour round trip in his car to go and collect the luggage from the airport so we can get it today. A TOTAL SHAMBLES AND DISREGARD BY BA FOR THEIR PASSENGERS’ BEST INTERESTS.

Much much better than my previous times on British Airways the food was spot-on and the service was really genuine and attentive

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.
