No cumpli mencionado trayecto por reasignacion de Copa Pero extraviaron mis maletas por su culpa

No cumpli mencionado trayecto por reasignacion de Copa Pero extraviaron mis maletas por su culpa

Pros: "Boarding was organized"
Cons: "They didn’t turn on AC until we landed in Lima, during bording they were hurrying people to get on their seats fast"
Pros: "Nothing. This airline is awful in every way imaginable."
Cons: "We booked tickets to Costa Rica with Copa and they just changed our flights to two days later than the booking. They didn’t even bother to inform us of the change we only found out because we booked through Kayak and they let us know. Apparently Copa expects you to frequently check your booking just in case they’ve changed anything and don’t feel the need to inform their customers of any changes they make. Then we were told we could get a Copa voucher to use for other Copa flights for having to cancel our booking and rebook with another airline as a 48 hour change to our flight made flying with Copa not doable for us. But the website kept telling us we had a voucher that was sent to our email but despite repeated attempts it never came through. And spent hours trying to get through to someone on the phone to sort it out with no success ever getting through. My advice. NEVER EVER FLY WITH COPA."
Pros: "Both of my flights were on time which i know sounds basic but all of the flights i’ve catched from SJO to X were late and this time my connection in Panama was only 1h15 and we got there earlier, so that was nice!"
Cons: "A bunch of seats were free and we were mostly sat all together (3 person next to each other).. With the covid situation i think it could be good to be more separate if possible"
Cons: "The amount of turbulence experienced was ridiculous. The landing was rough. This was the same for every flight with Copa on my round trip from SJO to MDE. This was extremely concerning."
Cons: "The seats are very uncomfortable but other than that it was wonderful!"
Pros: "Profesional, on time and quality service. A tremendous difference to the US Carriers. A+ based on price, service and amenities"
Pros: "Crew was great. Seat not super comfortable, worn out support. Entertainment very limited for five hour flight. One movie option playing on shared screens. A kid movie."
Cons: "More comfy seats and entertainment options. Crew, however, was excellent."
Pros: "Food was good"
Cons: "Different movie, more leg room but I'm tall so that is with any plane."
Cons: "If we were not forced to pass through Costumes and take our Luggages and go through security again, although we were in transit for couple of hours only. I lost my pierce and no one helped"

Avianca flights to Galapagos and back and well organized and on time.

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.

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

Flight attendants to show up on time, offer drinks and food.

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.

Avianca: you pay for a high-end flight and you fly like a low (very low) cost!

Wasn’t able to take the trip and no one could help me with a refund or rescheduling

My international flight from LAX to Argentina had one free check in bag included in the price I paid, however your crew in LAX made me pay $95 USD to carry it on! Please note I had only on small size luggage (carry on size) and one backpack. I demand my $95 USD back that you guys charged me illegally in LAX.

The flight was overbooked and the solution gave was unrespctful. I arrived 4 hour in advance in the airport and only after 2hous was possible suggest a different ticket with another company LATAM, I have accepted, but when I was checking in at LATAM the tickets was issued without luggage, what it is absurd since I have bought my tickets including it since the beginning. Due to the timing for the next flight was not possible return to Avianca to claim due to the distance between Both companies Avianca and Latam since were located in different terminals. I have insiste to the crew of Latam to call Avianca to solve it, but they could help they were alleging that only paying a thousand pesos Mexicans ($1,000 MXN) to dispatch my luggage would be accepted and I have no money at all. So I had to beg for others passagens, it was an humiliating to exchange luggage with who was platinum in order to return back the luggage in the connection airport in Brazil (GRU). I have no clue that a judicial process would be taken from my side due the lots of stress in sequence by the non professional treatment with a passenger that was just following everything said by Avianca.. Long hours of waiting until next flight and only arrive at final destine in 6hs later..

Pros: "Puntualidad"
Cons: "Quise comprar un equipaje 3 dias antes, la app es malisima, trate mil vecss Imposible siempre fallaba Lleve al aerop los comorobantes e igual mw cobraron el Doble, la gerete una maleducada me trato super mal, me pidio comprobantes, le mostre y no hizo nada Horrible atencion!!!!?? Desastre"

I missed my plane because there was a lot of people during the migration process. The airline has the chance to care for their clients and they could get the passengers missing in the flight. I lost a day of work and Montfort transportation to go back home and go to the airport again. Unfortunately the airline doesn’t care about that. I use latam at least 4 times a year, so I guess I need to be treat better. In addition, one on my baggages didyarricw to my destination. So frustrated with this trip.

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.

Our yoga retreat was cancelled and besides not refunding is, they would not even let us change dates or locations. As a matter of fact they wouldn’t even talk to us and kept referring to the travel agent, who said they couldn’t change anything and it was up to the airline to do so. They passed the buck until it was too late to do anything about it. Avoid Latham and Budget Air for your travel plans.

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 boarding process of back to front was really efficient and thoughtful with the pandemic. And the smocks the FA wore."
Pros: "Muito confortável. Boarding muito rápido. Muito bem atendido a bordo."
Cons: "Infelizmente o serviço de bordo não pode ser apreciado, mas entendo que é pela segurança dos passageiros."
Pros: "The crew was great"
Cons: "They should be on time but we left 30 minutes later."
Pros: "seat was comfortable"
Cons: "On a long flight, lack of drinking water during the flight, need to improve on this. Lack of communication needs to be improved"
Cons: "Would not let us board with 25 minutes prior to departure Because they lock their doors 35 minutes prior"

I paid extra for a comfortable seat in the second flight, but the plane didn't have those seats, the first one did

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.

My seat was broken and the crew had to find me somewhere else to sit. The crew was extremely courteous about this
