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.

Special AVML was terrible Movie choices were quite limited Otherwise excellent

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.

Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.

You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.

Premium economy was not what was shown, no leg riser, seats were broken and do not recline more than economy, food, we couldn't eat it was so bad, no menu 1 item and it sucked.

Our original flight was cancelled. This was a slightly earlier flight. We were business class and it was very good. The staff were marvellous and very helpful. Pity our baggage didn't make it!

British Airways is very good... Taxiing after landing took 35 minutes, can't really blame the airline but the terrible infrastructure at JFK.

Our section of the aircraft in premium economy was very cold. We asked the attendants twice to raise the heat but it never happened. Even with the blanket it was chilly for 10 1/2 hours

Really slow transfer after getting off the plane at Manchester, and lost luggage! Take the train, terrible experience on arrival

The flight was canceled and I was directed to Air France two days later than my plan departure day. This involve getting two more days of hotel and also not being able to get a boarding pass until I got to the Istanbul Air France boarding desk. It has been a troubling time.

I didn’t take that flight. My original flight was cancelled from Los Angeles. They rebooked me following day through Montreal My flight was LAX to YUL and YUL GVA

It makes no sense for several types of drinks to already be out of stock in the middle of the flight.

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.
