I missed my original flight due to miscommunication and it was a challenge to communicate with service personnel, since my Portuguese is limited. However they got me food and a hotel overnight and a seat on the next available flight.

I missed my original flight due to miscommunication and it was a challenge to communicate with service personnel, since my Portuguese is limited. However they got me food and a hotel overnight and a seat on the next available flight.

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

My entertainment did not work. I was very tired from the botched connection, and the poor sleep

Staff encountered friendly and helpful. Flight delayed 1 hour due to mechanical issue, but made it through Atlanta immkgration and security in plenty of time,

Only complaint is that the entertainment system wasn’t working on our seats and some others.

It was a short flight, sits uncomfortable No food was provided. Staff was lovely and kind .

For bus boarding, group 1 should have been sent on a separate bus ahead of the general boarding. It would have been nice.

They offered food. The crew passed by again offering water. I enjoyed the two seating section. I think is very comfortable instead of the three seat way, unless you seat in the middle; which it's not bad, but I wouldn't prefer. All and all, I think the lay out of the seating rows are better than other airlines so far( I haven't tried many anyways). The lay out makes the getting in and out to use the restroom less uncomfortable and cramped. First time flying with Latam. I will fly with them again

Terrible They charged me 157$ for excess baggage even though my bags were within the normally accepted limits Flight was late. Service was poor. The snacks were really bad

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

My seat was the only seat where the tv didn’t work. The crew Carol and Jua were very rude and refused to move me and my companion to a seat where the tv was working. I traveled on a 8 hour flight with no entertainment nor able to choose my food. I was told by Jua to call customer service for compensation. The customer service team and escalation team refuses to compensate me even after verifying and speaking to the flight crew, whom confirmed they told me that. Horrible service, horrible freezing cold flight. I would never fly Jet Blue again.

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.

Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

Boarding went fast. Lisbon's gates are too small for the flights they serve.

The staff were great - very friendly and chatty. I checked in online at 9.30am, when check in had opened at 1.30am, and choices were already very limited, so act fast.

Awful experience all around, misleading booking led to disgraceful baggage charge at gate. Tiny uncomfortable seats with little drinks served in small paper cups filled halfway. Difficult to use bathrooms the whole flight and now on the way back we’re stuck in Lisbon a day later because of a diversion on our connecting flight, I will never fly this airline again.

I suspect that there was an item pilfered from my bag at the TAP automated check-in counter on March 26th at Heathrow Airport around 11:30am. I think that the employee assisting me with my bags took something out of it when I was not paying attention because today, March 27th there is a notebook missing. Please check the camera to see if indeed this occurred. My description: Male, African Decent, 5'8, 180lbs medium build, wearing trousers and a jacket. Employee description: Female, Indian Decent (guessing) 5'7, slight build. Flight 1359, London to Lisbon.

Very happy with the airline. No issues or complaints! Will definitely use TAP Air Portugal again,

Those seats were very comfortable. Nice leg room and food was great 👍

because the previous flight operated by BA was delayed, when arrived to the gate, I was surprised that I was taken out of this flight and they rebook me but with a different seat

We arrived at 430a for our flight. We only had carry on so we were sent to security. The BA person was tagging all carryon in case a shortage of bin space. We were on the plane like 20th and told we had to check carryon because it had a tag. Unexpected and unnecessary

The travel on premium economy class was very positive. Comfortable with plenty of space and leg room. The service throughout was top notch. Crew members were kind and helpful. Food and entertainment were excellent.

Based on my wife's damaged condition, BA very kindly upgraded us from cattle to business class. MUCH appreciated!! One of these days, as it gains more experience, BA MAY learn how to depart on time (with over 30 years experience with BA, no flight has EVER managed to leave on time), Once airborne, the entertainment was ever so very pedestrian. But the flight was uneventful and the cabin crew's service was superb. And whichever driver landed the aircraft had obviously done it before. But BA unfortunately is learning from that scuzzy airline Delta. Delta is ALWAYS stunned when one of its aircraft actually turns up anywhere and is NEVER ready to receive it -- even when it turns up where and more or less when it is supposed to, NOT an example worthy of emulation.

Incredible. The upgrade to Business was a phenomenal way to end my trip, beyond grateful for the generosity and hospitality.

Great! Apart from small sitting in one the flight everything else was good

It was pretty decent mostly cause I have leg room.

Flight was delayed leaving Heathrow by 1 hour. No onboard entertainment and basic food available for purchase.

because of delays of earlier flights, we did not fly BA to Reykjavik. We booked an alternate flight through Businessclass.

We had a quick connection in Bogota. When we landed, they waited on the tarmac for 25 minutes before they let us deplane. I told the stewardess that we had less than 15 min to get to our next international flight. She did nothing except tell us we had time to get there. We found out later that they already scheduled us for a later flight, but they didn’t say anything until we ran to our gate. The plane was still there but they wouldn’t let us board. When they changed our flight, they gave my wife and I a voucher for food that was less than $40 in value. That buys very little in the Bogota airport.. it barely paid for two fruit juice drinks. There lack of communication was very unprofessional. This will be our first and last time using Avianca.

The seats we had, did not recline and there was very little cushion. There was no entertainment module in the seat.

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.

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

$120 for a carry on bag !!!!!! Insane. Back-breaking seats. Do not recline. Food service is a disgrace. They give only water and a salty snack. Everything else has a price.

The fees for baggage were outrageous. $130 for carry on and $150 for check in for an international flight. The seats did not recline. We were not even offered water. Had we known all of this, we would not have booked Avianca at all.

No water for a 5 hour flight entertainment not working seats with little room for knees when person in front of me reclined kept bumping my knees.

Seat space was terrible no food on a six hour flight

Avianca flights to Galapagos and back and well organized and on time.

I flew with my service dog unfortunately they didn’t allow it to flight on the canine, but ok, the only problem was that when I arrived to Quito it took 1 hour to deliver my dog, they were supposed to deliver it the moment we get off the airplane.
