TAM is a real disappointment. We had to jump on a crowded bus for a 6am flight - although there were at least 15 available fingers that could have been used by our plane. Then, we were placed on row 30 - the last row of the plane, despite having purchased the tickets a long time ago and being TAM gold plus members. Note: worse seats on the plane. Great way of rewarding your frequent flyers TAM ! I now remember why I stoped flying internationally with TAM and moved to American, United, Swiss, Lufthansa and BA. TAM has no respect for its customers.

Everything was as you would expect in coach - fine. Flight was close to on time.

It was confusing because I got a notification that my gate was changed when in reality it wasn’t

Flight was great Customer service was questionable until we found someone at checkin to help us. One young lady took all our passports disappeared for 15 minutes, came back with nothing done, handed to someone else and left for lunch. Very complacent. Baggage was very expensive until we went to the service counter and a separate person helped us. Even with platinum status they wouldn’t allow free bags. We will continue to fly Delta as our preferred carrier but will avoid checking in with Latam. Dr. Armand Radke

It was ok for the most part, it is missing something

Hostile flight attendants. Second flight with Jose so much better. Arrived 1/2 hour early. Thanks.

As usual, LATAM tried to rip me off as a Gringo. They ignored the fact that having paid for my assigned seats, I was entitled to one free luggage per person, up to 10kg, and tried to charge me USD40 per item. While they ripped me off by $160 on my outbound flight (4 luggage pieces, which should have been free), I vehemently protested this time around. Note that they only request this from gringos, not from Spanish speakers. LATAM behaves like a racist extortion organization.

The flight from PDX to New York was cancelled, and I got rebooked one day later. Because of this I missed a meeting at my final destination, EZE. I now need to stay longer in Argentina, and was told the tariff difference was $780 plus $150 penalty! I am not using my return ticket, and have purchased a one way ticket EZE-PDX for $606 with another airline. SHAMEFUL

Pros: "Nothing as we could not take the flight."
Cons: "Allowing the option to change your ticket date, but failing all debit and credit cards payments offered, actually means that they are not allowing flight changes due to COVID related issues like they say they do. We had to book new tickets with another airline to get home."
Pros: "The crew was great"
Cons: "They should be on time but we left 30 minutes later."

More than 3 hours of delay and not even a snack was given.

GOL made the flight experience a true delight. Everything was smooth, from the check in process, to the disembarking moment.

Boarding was very expedite. The chairs are fixed you can't rest comfortable during the flight.

There was absolutely no food or drink service unless it was paid for. I am not used to this.

Awful. I checked in online and there was no option to pay for baggage, at the airport when I checked in my baggage was received and Iwas not charged. When I got to LA during the boarding process I was told I didn't pay for baggage, the crew resolved I was let in the plane. When I got to my final destination my baggage was not there. It took me two days to receive my baggage. Bad service ever!

The temperature was cold and the food that we had to pay for was awful. The crew didn’t even offer a free glass of water. It was a long, expensive and uncomfortable flight.

It is better at the jfk than my home country. It was very easy and everything was 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.

No complimentary food and beverage (water, soda, coffe) is offered for a six and a half hours long international flight, not even in premium economy, just to try to squeeze a few more dollars out of the passengers. First and last time flying with Avianca.

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.

Larger seats on this plane made the ride reasonably comfortable. Our next flight, from Lisbon to Copenhagen, was inconsiderately tight and stressful. The seats were smaller, space between rows was very limited (no button or mechanism to even slightly incline anyone’s seat), and leg-cramping under the seat in front. Just like sardines in a can. Really felt for all the tall Danes on the flight. Their knees were pressed against the seat in front throughout the flight.

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.

Everything was nearly perfect, and TAP staff were especially helpful when we missed our connecting flights and had to get on the next flight to Rome. The only aspect that could have been better was boarding: it was somewhat disorganized, which created a bit of stress. But in the end, everyone got on the plane, so the less-then-perfect boarding process did not take away from the overall excellent experience.

Two of three flight attendants were not super kind as I would expect. The very kind young lady in my section was wonderful but then lady and man up front were not. Sorry but it makes a difference !

O comissário não nos serviu bebida no jantar. Quando voltou somente serviu água.

Very little space between chairs, making any long travel very uncomfortable. Food is also very basic.

Airline attendant never walks along the isle to check if everyone is ok. The food is worst I’ve experienced. Chicken pasta is very salty while the fish is bland and over-cooked. Only two toilets for the entire economy section.

TAP needs to allocate gates at airport. Boarding and disembarking using buses is tortures in hot weather.

Crew and flight were excellent! THIS is how a crew and a pilot should act! They were nothing like our Rome to Lisbon flight! The few things that could be better? Organize the buses better and have better food choices. Also get bigger glasses for soda, water and juices. Other than that, this flight was excellent! John and Barb Sanford Plainville, CT USA

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

Flight was an Iberia Flight on Level but seemed to be outsourced to a 3rd airline - Wamos. Seating pattern was different than when booked, we waited on the JETBRIDGE for 45 minutes to board, food was terrible. Movie options were limited to about 20 and very old, TV shows was limited to about 15 and equally as old. Staff was fine but definitely the "b-team". Landed about 60 minutes early and waited on the runway for 45 minutes - despite that Logan Airport in Boston recently added new gates. Mediocre experience at best.

I liked the friendly crew and desk staff, all very helpful. I was surprised and a little annoyed on my outbound flight from LGW to MCO as I had prepaid and booked my seat, which was all correct at check in on my boarding pass. when I got on the plane someone was in my seat ! I was moved to another seat. The food choice is quite limited and I feel that an option of a muffin for breakfast snack would be welcomed, not everyone wants egg or bacon wrap. The choice of entertainment is good, plenty to keep you busy on a long haul flight. I liked the option offered to have the cabin bag checked into the hold, it saved me as an older, lone traveller lifting my case into the overhead locker or finding there was no space.

My luggage never arrived in Miami; still waiting a day later.

The only comment I have is why do you sell snacks on board? They should be free. When we take domestic flights here in US, our snacks are free. Also, please communicate with me in English. I received so many emails way before my flight that were in Spanish that I had to ask my son to interpret for me. You should be WELL AWARE if the customers you are communicating speak the language, it does mean that we speak and understand Spanish because we are traveling to Spain, NOT NECESSARILY! Thank you!

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I like the team but I don't like the food you provided with money. I want free food and free water.

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

I’m hoping for WiFi included. Everything else was very good

Seats, comfort level ugh. Crew was not attentive, only to coach

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.
