Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

8.0 ExcellentDavid, May 2024SJU - JFK
Read more about Delta reviews

Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

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.

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!

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"
Cons: "The turbulence was really bad ! I couldn’t sleep at all !"
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: "Sure. I had booked a two week vacation in Brazil. All hotels, car rental and guides booked. Copa changed my fligjt at the last minute and out of the 14 days vacatipn I had in Brazil, they would have me spend 6 days in Panama City!!! Lost of small fortune with hotels, car rentals amd had to buy another ticket with Latam. They are a scam!!"
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"

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 was charged $140.00usd for my backpack the only luggage i had was my backpack

More than 3 hours of delay and not even a snack was given.

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

Boarding was very expedite. The chairs are fixed you can't rest comfortable during the flight.

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.

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

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.

I flew with my service dog unfortunately they didn’t allow it to flight on the canine, but ok, the only problem was that when I arrived to Quito it took 1 hour to deliver my dog, they were supposed to deliver it the moment we get off the airplane.

No complimentary snacks, food, beverages (even water) blanket and pillow on a 6 hours long flight (economy comfort). A low form of nickeling and diming. Lost a recurring pessanger over a soda. Will never fly Avianca again.

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

We enjoyed that we boarded and took off on time. We didn’t like that our connection flight was a twenty minute walk through the airport with only one hour in between flights.

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.

Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

The flight was actually good the staff was all friendly, but I have to give it a bad rating because my luggage was damaged and I was not able to claim that it was damaged. I only realized it once I got to my hotel and when I tried to contact Air Canada it was almost impossible. The number give to make claims is only for US & Canada yet I was in Seoul, when I tried contacting the number for Seoul I was once again told to call the other number or to return to the airport (which was not possible at the moment). So very disappointed that there was no way to claim my damaged bag and now I have to try to get a new bag while on vacation.

Mess up with not assigning my husband a seat when our two tickets were purchased at the same time. They put us on standby. We were almost bumped off the plane at the gate before departure. Luckily someone volunteered to get a later flight.

The flight itself was ok the staff was great and so was the inflight food. The biggest problem was that my luggage was damaged (the zipper pull from both sides of the zipper where completely ripped out) and I didn’t notice at the airport but at the hotel and when I tried to make a claim it was not possible for me because I have to either call (which is difficult because I’m in another country) I tried to call every nombre given to me but the one that I need I was never able to contact and going back to the airport was not an option. So it’s basically impossible to make a claim if you are abroad. Very disappointed that there are no other ways to claim a damaged bag and now I need to buy a new luggage while on my trip.

Pretty good service and US Migratory officers providing services in Canada was awesome, because the arrival was quick and smooth

Rouge needs to offer seats with better pitch in economy. Many sick people on a full flight.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

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.
