On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The flight was delayed but we got to our final destination.

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

The plane was one hour late cause they were doing some reparations with us on the plane no mention I was in the first seat and the door was open the entire time with 8 degrees! The plane was totally dirty no mention old ! The staff was nice but no put together, the attention to details and passenger experience is missing and i always travel first !!! Is better the lounge than the plane! KLM/air France every details is taken care maybe you need a creative creator or experience client need asap was terrible and not memorable for the price that I payed very dissatisfied

Flight was great. DELTA did a fantastic job! ATL was busy, as usual!

Flight was great. DELTA did a fantastic job! FLL airport was chaotic!

I received the two differed meals: chicken and pasta. I asked and I received. I am anti-wasting food!

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

The flight attendants were friendly and seemed to like their jobs. I am not a high maintenance person, but they seemed to respond to people's needs and requests in a timely fashion with a smile.. I appreciate the benefits of complimentary snacks and beverages, as well as the relatively inexpensive checked baggage fee. (Although I would like it better if it were free! :) ) The only improvement that could be made to make the boarding process more efficient is to board the plane from the back. The alternative would be to board people with only a personal item first. This would reduce the wait time while others are stowing their baggage.

Boarding was slow again. Too many people with too much luggage.

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

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

Copa me elige como "voluntario" para cambiarme y poder enviar a una familia a la cual había sobrevendido los tiquetes. Finalmente me envían a las carreras con Avianca, pero Copa lleva mis maletas hasta Panama y luego las devuelve a mi aeropuerto de origen, dejandome sin mis pertenencias y además no asumen la responsabilidad ya que dicen que es problema de Avianca Literalmente vi cuando el avión de Copa se lleva mis maletas, sus funcionarios en Bogota, incluyendo la gerente local me aseguran la entrega en Miami, pero simplemente era para poder engañarme y dar el cambio de silla por sobreventa

the planes are not modern there are no phone chargers

I liked the friendliness of the crew and comfortable flight. All good.

Cons: "Copa is trash . Doesn’t accolade passengers with hotels . They except people to wait in the airport for 14 hrs lay over when it’s their fault ! Straight trash . Poor 79 year old lady had to stay at the airport cause her family was 4 hours away ! Trash trash"
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"
Pros: "You are so good all the time."
Cons: "We understand that this time is tough because the Coronavirus, they took care of all of us, and also they were kind and friendly. Thank you so much, for everything"
Pros: "No drink because didn’t open de bottle. No one care about it."
Pros: "Yo había ido al sanitario, cuando regrese ya habían repartido los jugos, la aeromosa muy atenta me llego a preguntar si quería jugo y me lo llevaron."
Cons: "Al momento de dar las instrucciones de seguridad, creo que los pasajeros prestan más atención y entienden más si hay alguien del crew al frente dando ejemplos de cómo hacerlo. Todo lo demás excelente!"

I didn't realize they didn't have bathrooms on the plane. Almost had a very bad situation.

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

It’s been some time since I saw the plane and the cabin that old and worn out.

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.

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.

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

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."

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

The flight I was connecting with waited for me even though my 1st flight was late. I really appreciated that.

The seat is too hard and my back and bottom are having servers pain

it was our first flight with Air Canada. The flight was very good. The arrived 10 minutes early. The crew was attentive and very professional. The seats were comfortable and the food was fine. There were a lot of movies and TV shows to choose from. The boading was OK, but it is more about the Montreal airport procedures, but not about Air Canada.

Crew was very respectful and ready to serve. Much better than before.

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

It was an enjoyable flight. I guess the airlines will never go back to catering, they save so much money.

Lovely staff for a short flight! Complimentary wine too made me happy.

5 delays to departure. Finally left 2 hours after scheduled time. Further issues with “paperwork” when we were ready to push away from the gate. Air Canada has a real problem with flights between Montreal and Toronto over the last 24 months. Of my 12 flights, 8 have been delayed or cancelled. With no compensation. I now drive between Toronto and Montreal whenever I can. At least I know I will get there when I planned to.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

Terrible crew. Mediocre food. Terrible headphones. No Bluetooth connection for entertainment. Crying babies. Horrible experience.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Difficile quand le gate change, les deux fois. Quand on m'a changé les sièges que j' ai réservé, les deux fois. On m'a dit que j'allais être remboursé et rien eu encore
