We liked the way we were treated by the sraff at lima airport counter and the the flight attendants. We did not like the fact that the kiosks at airport rebooted after we entered our information and then told us that there was an issueand we needed to go to the counter. Such a waste of time for a group of 6. Once we got our boarding passes there was no assigned gate so we did not know where to go.

We liked the way we were treated by the sraff at lima airport counter and the the flight attendants. We did not like the fact that the kiosks at airport rebooted after we entered our information and then told us that there was an issueand we needed to go to the counter. Such a waste of time for a group of 6. Once we got our boarding passes there was no assigned gate so we did not know where to go.

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

Good check in process Poor information on payments at Lima airport

Apart of Sky miles delta. And they go everywhere in Brazil

On board crew was very good. Crew was friendly, snacks were good, especially the chips. Seats seemed a bit cramped. Boarding seemed unorganized, as we were instructed to get to the gate an hour early and then just stood around until boarding.

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Poor, the airline was not able to help me move flights.

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.

Business class seats aren't comfortable. Food was not good.

Great service overall. One of the best international flight experiences Ive had.

Didn't make announcements during boarding, flight attendant seemed annoyed when I asked for water. Too many hours between flights. Confusing check in at the Lisbon airport.

The flight crew were absolute rock stars. When they came to the gate they looked like royalty, so chic. They also were extremely kind. Food was good and I loved the lack of plastic waste. The flight was lovely and smooth.

We were unable to check in due to technical problems on TAP’s end. The flight was delayed forty minutes with no reason given. We received timely notice of the flight delay. We were also notified of a gate change. The new gate was at a different terminal. When we got to the new terminal, we learned that we had to go back to the old terminal first to check in. This information should have been included along with the gate change notification. Also unexplained, the steward skipped us when offering breakfast.

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

Delayed at the beginning and the end and almost missed our connection

Menzies group staff not very sympathetic good at breaking up families during the boarding process

Kayak let me choose these flights on TAP but then after 2 months, cancelled my flights because they didn't think 90 minutes was enough time for the connection. I notice that neither flight was actually cancelled. Just my reservation. Why let me go through all of that effort to find the right flights for us, only to cancel it from underneath us 2 months later leaving us scrambling to find an alternative?

We upgraded to business class. Nice seat with lots of room but otherwise not impressive.

The flight was long but everything went well. Crew was helpful and very attentive. Food was good and the entertainment options were many.

My long-haul flight experience with this airline was not very pleasant. Earphones were paid, and no eye mask or other amenities were provided. The meals were served in cardboard boxes with plastic cutlery. The restroom was unclean and ran out of toilet paper. However, the boarding process was smooth and well organized.

We experienced a delay of almost two hours before takeoff. For a flight of more than 10 hours, sitting on the runway for two hours is quite exhausting. The airline did nothing to attend to the passengers during that time. We were not given any courtesy drinks or snacks—only the bare minimum during the flight. The crew seemed very apologetic, but apparently they have restrictions imposed by the airline, because despite their friendliness, they provided strictly what was necessary and, of course, everything else was for sale. However, after a two-hour delay, one would expect at least complimentary beverages. In addition to this, the space between the rows of seats is inhumanely narrow. Air Europa should review this for such long flights and be a bit more considerate and humane with its customers.

I flew in business a couple of months ago, it was great, tried again in economy, it is the cramped seat I have ever been into, for an overseas flight across the atlantic it is inhumane to put passengers in such cramped space. Other than that, everything ok. Took a second flight from Madrid to London, also economy and it was roomy and perfect.

No WiFi on the plane. Crew was insensitive to my medical supplies and medicine in my carry on. If the crew was monitoring passengers putting 2 bags in overhead bins there would be room. We sat for 2 hours extra. Iberojet is horrible never again.

There was no water in one of the sinks in the executive area, which is unacceptable as we could not wash our hands after using the restroom

Like I said the experience was mediocre. Nothing special about this airline.

This flight was delayed by more than an hour. The seats are uncomfortable ans do not recline properly. I prepurchased a wifi pass, but wifi was not working on this flight at all. The food was bland.

Food situation was bad. Also movie choices when compared to other airlines was terrible. Seats very narrow. My tv didn’t work.

I was not allowed to cancel the flight, customer service is atrocious

Cancelled flight and re booked seats were a downgrade. British Airways said the upgrade was t available but when I checked it was but then they wouldn’t make it right

The crew was exceptionally good. Came around with snacks and drinks multiple times during the flight. I asked for hot water and they remembered. Responded to call light promptly. Very pleasant. The aircraft was also kept very clean. Boarding was organized. Overall was a great experience.

The boarding was a mess as there was another document check in the small congested area after the stairs at the gate. No food is offered for Economy travelers except for a cookie and a small water bottle. No entertainment is available since it’s a short flight. But at least the seat reclined as opposed to my flight to Faro.

Flight attendants need to come by a little more often to pick up trash.

Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.

The whole experience was excellent, O can say out from Miami the best airline to travel with for any European destination. Since the ground staff to the inflight crew attention was great, service on board 10 of 10. Finally the 380 is very confortable and nice to travel.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

I had a mixed experience on this flight. The plane itself was comfortable, the flight was smooth, and the entertainment selection was excellent with plenty of movie options. However, the service fell short. I had an entire row to myself and fell asleep with a blanket over me. A flight attendant, Karleigh, woke me up to see if I had my seatbelt on, which felt unnecessary given the situation. Meanwhile, trash sat uncollected on the tray at the end of the row and was never picked up. During the second meal service, no one woke me up, and when I used the call button multiple times, there was no response. I eventually had to walk to the back to ask for assistance. There was also a long stretch without snacks, and when I requested something savory, I was dropped off sweet options, which wasn’t ideal. Overall, while the flight itself was comfortable, the lack of attentiveness and responsiveness from the crew made the experience disappointing.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

The employees at the gate were not communicating, they preferred to give the upgrade to pilots and not to the elite passengers Every flight I more disappointing, clients shooed be priority instead of other employees even if they are pilots, there was plenty room for pilots in economy

This was my first time flying with you guys and my very last! This was the most horrible experience!!! There was not even tv in the plane! How cheap can this airline be!!! I paid so much for my suitcase!!! I would never fly with this airline again! The crew are very rude!

They should provide water to passengers who ask for it

Seating was tight. Seats don't recline. Initial flight was cancelled. Lost two days of vacation.

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

I upgraded to businesses class. Because of that the flight was comfortable.

I actually upgraded to the medium level of seats from basic and even doing that it may have been physically the most uncomfortable flight I have ever had. They packed everyone like is a train to death camp. It was a red eye so I hoped to get some sleep but it was physically impossible to find a comfortable way to rest. I met other folks on the same flight and they said the same thing. It was an utterly miserable flight and if I have any other options I will never fly with them again

Avianca has transitioned from full service legacy airline to "low cost" but has now became a strange hybrid (minimum leg space, started offering business class in domestic flights again, charges passenger for printing boarding pass, etc.). National and international coverage and destinations are really wide but service is not at its best

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

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