Airline reviews

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 Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.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.

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

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

Placed us in the last rear row of the plane so could not recline seats because of the rear wall, and also made it more of a tight space when the passenger in front reclined their seat. While understand seat assignments, every passenger should be afforded a reclining seat. The odor control scent from the restrooms was overwhelming strong. My wife and I could not deal with it, and she suffered a terrible headache as a result. I kept getting hit by the crew since I was on the ilse seat. No apologies, nothing. They made me feel like I was supposed to take the beating for a 3 hr flight.

There was no individual at the front check in when I arrived. I waited for at least 15 minutes and walked around asking security/janitors if they could help and they did not have a solution. So I had to take my checked bag through security and they threw away some of my items. I ended up making it to the gate only a few minutes before it closed due to my waiting for an agent at check in.

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

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

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

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

I never got this flight. You sent me to Chile!!! And from Chile I got the other flight to São Paulo... I've arrived 7h latter than I was supposed to arrive because of Delta delays.

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

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.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Overall a good experience, however Wifi was not working on the flight.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

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

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

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

I receive a service for what I pay, so it is fair.

They charged me $120 to check one bag and then charged me another $120 for a carryon. Ridiculous!
