Airline reviews

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Connection flights should be spaced out farther because too close I missed my connection.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

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

Friendly crew, good food options, food not the best and seats not as comfy but that’s typical.

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

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

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

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.

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

Apart of Sky miles delta. And they go everywhere in Brazil

On board crew was very good. Crew was friendly, snacks were good, especially the chips. Seats seemed a bit cramped. Boarding seemed unorganized, as we were instructed to get to the gate an hour early and then just stood around until boarding.

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

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

After boarding, there was a small issue with the aircraft which caused a delay of about 45 minutes. During boarding and while passengers were being seated, the plane was being refueled. There were also a lot of unusual noises during the flight, which was not very reassuring. In addition, there was no WiFi or entertainment available.

The worst experience I've ever had because the "people" @ Avianca wouldn't let me fly because they said I needed a round trip ticket

Seating was tight. Seats don't recline. Initial flight was cancelled. Lost two days of vacation.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral

I actually upgraded to the medium level of seats from basic and even doing that it may have been physically the most uncomfortable flight I have ever had. They packed everyone like is a train to death camp. It was a red eye so I hoped to get some sleep but it was physically impossible to find a comfortable way to rest. I met other folks on the same flight and they said the same thing. It was an utterly miserable flight and if I have any other options I will never fly with them again

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

Deplaning was a mess, I sat in business (seats are horrible) and the front door had a problem so we had to deplane from the rear exit. The stairs were not tall enough to reach so there was a large step down from the plane to the top of the stairs.

Staff are the rudest in the industry … awful customer service … will never fly Avianca again

Pros: we leave and arrive on time Cons: the most uncomfortable seats ever. You cant recline at all your seats. No entertainment No TVs flight attendants didn't provide even a glass of water. You have to go to back of the airplane and ask for one. I am Colombian and I remember seeing the flight attendants very neat, elegants which is or was a staple of Avianca.it was one with tennis shoes, no male up, the hair was messy... that was really odd.

Here we have another airline flying to Guatemala but doesn't have a plus or a less, just in the middle. Why? Well, first we don't have even free water Movie selection is poor Seats don't recline in some places Food selection is carb based Forgot to mention, customer service on the web is the worst. Good things; Very reliable on schedule Kind crew
