Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Not very good, they nickel & dime you for better seats & pay extra for the checking in bag, bad service all the way around

Flight from Lima to São Paulo didn’t have USB plug to charge the cellphone.

It was a good experience, the flight was a little too long & the food was ok

Check in of my luggage which needed to be paid for was excellent. Thanks to Nora

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.

This airline is full of junk fees. After paying to get my kids to sit with me, we were asked at the gate to check in our roller bags and pay $40 for each one. Peruvian passengers all took their roller bag in the plane. I don’t appreciate airlines who spot the gringos to tax them more.

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."
Cons: "I needed to change my ticket and Kayak had another agency issue the ticket. Kayak does not change tickets and the third party and the airline said only Kayak could make the change. Having to purchase a whole new ticket from the airline, save the money and frustration and avoid Kayak and just book directly with the airline. The ticket would have and should have been changed with no fees. $325 lesson learned."
Pros: "Yes"
Cons: "Serve some type of beverage with out charging a lot"

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.

I don't think anyone actually reads these comments, so I won't spend much time on this submission. If you want to talk, you know how to reach me. The D/FW manager of Avianca (self-identified), Juan Calderon, insisted I buy an onward ticket from San Salvador even though I have diplomatic status in El Salvador and live here. It cost me $1,393 and Mr Calderon would not let me make the ticked flexible so I could get a refund. He went out of his way to be rude to me. He gave me seat 32K -- windowless window seat in the last row and did not offer to let me upgrade even though there were plenty of seats. I have flown well over a million miles in my life and this is the worst experience I have ever had. I would like a refund on the ticket I was forced to buy. Just awful!

This is the Spirit of Latino travel. And don’t even get me started on customer service.

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!

There was no food or drink service, couldn’t even get a glass of water for free. It was a long and expensive flight to not offer food or beverage on the plane.

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

There is no food. There is no in-inflight entertainment. The seats are cardboard. The airline is a living hellscape.

My experience was amazing! They helped my elderly mother board on early through a wheelchair and were accommodating to have us sit together since our seats were in different locations. When landing at the airport in GUA they were very helpful with full of hospitality.

No complimentary snacks food, beverage (not even water), pillow and blanket on a 6 hours long flight (including economy comfort). A low form of nickeling an diming. Lost a recurring passanger over a soda. Avianca never again.

Flight departure late. Got late in Colombia making us take a different flight next day. Avianca airport crew messed up my ticket so when a I got in Brazil I didn’t have a ticket for my destination. Had to buy a new ticket out of my pocket.
