Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Everything could and should be better. We are paying for, it's not a favor, it's a service and should involve quality, responsibility and respect.

Seats were comfortable, 8 hours. One flight attendant was not appropriate in his verbal response: "Please, DON'T touch me.", after being tapped near his elbow after being made unaware he skipped serving me & had passed further down the aisle.

Boarding in Amsterdam is always chaotic. More complicated than needs to be ( boarding pass checked twice, once for general security, then by the airline). The bathrooms on this flight are dirty, and smelly. The food was mediocre at best The crew was decent

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

I was flying business class, and the French fellow passengers were super noisy. It was not a comfortable flight. And the crew was not helpful.

Boarding was a mess, they call all priority members without distinction so gold, platinum, silver were all mixed together in a long line which defeats the purpose

Entire experience from check in to landing was amazing the flight crew was excellent and friendly. Seats were comfortable.

Boarding was confusing from staff telling going to preboard and than to group 1 Airplane was not cooling at the beginning

Avoid at all costs. My wife had to stay back on a connecting flight as her parents flight was delayed. 10 days later on the way back they cancelled all our flights. We had to rebook all four of us on the next days flight.

The food is terrible I ask for water never got transport my mother we’re late and my sister from Lima was the worst waiting to long for wheelchair

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

Seats were awful. Media should have been included for such a long flight.

A lot things happened in this trip.The fly should be less stress.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

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.

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.

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

LATAM is a great airline who takes care of there guests. They consistently walk around and see if you need water in addition to taking care of all the passengers. The chicken in process is really easy and I’m always offered a chance for an upgrade which I appreciate.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

LATAM’s crews are fine, but God help you if you need any customer service. Their app and website never work, with error after error. Trying to solve anything over the phone is painful, and lastly, the boarding pass LATAM gave me to board the flight with Delta was invalid and I had to purchase an emergency one-way ticket at the last minute to get home.

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

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

Everything was fine except the end of the flight. We spent more than an hour circling around Miami due to weather conditions. That was not good.

They lost my bag. ... And I asked them 3 times to 3 different people if my checked bag will maKe it all the way - they all confirmed and at the end it was left at the connection... Bravo

Cancelled BOYH legs of our flight home 30 min before initial boarding

Cancelled the flight half hour before boarding. Then cancelled the connecting flight too.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

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!

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.

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

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

Boarding was late due to the company’s that cleaned the aircraft (very poorly done) and the catering company. The entertainment system was not working for this six hour flight, uncomfortable seats in business (barely any cushion or recline). The airline staff is very good but the planes are horrible and not well maintained.

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

I had to go to the boarding counter for them to enter my return flight as it’s not with Avianca. There was a long queue as there were lots of people being called to the counter.

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Horrible experience. Flight cancelled. Arrived at destination 12 hs later. No one gave us an answer or any information. Very very poor service. We won’t ever travel again with Avianca
