Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was very warm the entire time, despite my vents being open. Additionally, we didn't have internet on our personal devices

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

We were made to check our carry-on luggage because it did not fit the measurements. That’s what we were told, but I saw plenty of carry-on luggage on the plane that was the same size as ours

Flight Crew Review The crew was absolutely amazing from start to finish! They were friendly, professional, attentive, and genuinely made the flight feel comfortable and enjoyable. Every interaction was pleasant, and they went above and beyond to make sure passengers were taken care of. You could really tell that they cared about providing great service. I truly appreciate their kindness and professionalism and would be happy to fly with this crew again!

stood in line to check in luggage for nearly an hour. very poor service and not excusable

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Do not book it’s a scam! They stole $1200 from me

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

A lot things happened in this trip.The fly should be less stress.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

I would like a glass of wine or some kind of alcoholic drink.

Very long delay but we just made the connection. The requested wheel chairs were not there so I had to assist/carry BOTH of my parents to the gate while carrying their bags so we could make the connection. The plane had no entertainment system and NO WIFI, legroom zero. Restrooms on ALL of flights were dirty and one restroom did not even work properly. I was surprised to see COPA like this since my flight with them in 2013 was incredible, the seats were amazing and the food options were spectacular. Of course, I see this kind of service on many airlines now, with services and hospitality at an all time low. The worse part of the trip was seeing my 90 year old parents go through hell on these flights and having to try and rush to a gate to make the next flight. Never again

Abysmal overall. Delayed flight caused me to get in with an only 9 minute connection. No help from flight attendants or gate agents to try to make the connection. Second flight left 5 minutes early despite not having at least 10 people on it, including me. Rebooked 24 hours later. I asked four separate delta agents how to ensure my bag would get on the rebooked flight and all assured me it would be there. Landing in Rio right now, 24 hours late, and just got an alert that my bag didn’t make it. Horrible overall experience.

I missed my original flight due to miscommunication and it was a challenge to communicate with service personnel, since my Portuguese is limited. However they got me food and a hotel overnight and a seat on the next available flight.

It was a bit unnerving to know that flights are generally oversold. We chose not to pay extra to reserve a specific seat, without realizing that that makes us vulnerable to being bumped. Everything else about the flight was great.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

The seats are getting smaller and smaller. Very uncomfortable trip. More than in other airlines

I do not speak Spanish or read in Spanish When asking for help, people were hard to find they spoke quickly and pointed a lot directions for where to go and what to do we’re unclear. Which made my traveling uneasy.

Flight was great Customer service was questionable until we found someone at checkin to help us. One young lady took all our passports disappeared for 15 minutes, came back with nothing done, handed to someone else and left for lunch. Very complacent. Baggage was very expensive until we went to the service counter and a separate person helped us. Even with platinum status they wouldn’t allow free bags. We will continue to fly Delta as our preferred carrier but will avoid checking in with Latam. Dr. Armand Radke

Another American Airlines flight, another significant delay. At least this one wasn't canceled like many others have been. This time we sat on the runway at LaGuardia for 2.5 hours. By my count that is 7 American flights the last three months that have been delayed 2 hours or more or canceled entirely.

There was no clear update on the flight until last minute and made it an hour delay. No clear flight aircraft or incoming flight which we will be boarding. We would plan accordingly for our connecting flight. This is one one the worst service, I also had to buy an another ticket with different ai carrier. American airline was not letting me plan my trip, made us just waiting. Not a good service at all.

The plane was delayed after we boarded - although they sent an email to my work email (which I did not get until later) there was no announcement from the PA about the delay in flight. Fortunately, they made up the time in the air and we landed around the original time.

My luggage was lost at some point during my layover between Chicago and LHR. I landed Tuesday morning, and did not get it until Thursday night. Ironically, the people at the ticket desk had added a “priority” sticker to my tracking tag.

My experience was fine, with one surprising exception. After leveling off at cruising altitude, the main cabin flight attendant made an announcement that he had a cold, so he would not be coming through the aisle to provide cabin service. He claimed this was in consideration of his health and safety and ours. However, if passengers wanted a beverage, he invited them to come to the back of he plane, where he would provide service. I understand that a flight attendant's primary responsibility is to ensure passenger safety, but a secondary role is to provide service. If this flight attendant was too sick to perform his duties - and if he truly cared about passenger health and safety , as he claimed - he should have stayed home and called in sick, rather than exposing the cabin to his germs.

The flight was delayed multiple times. Breakfast was not served and only an apology given and statement that we could find better pastries in Paris. Seats were extremely narrow and uncomfortable.

We waited over 30 minutes for a gate in Chicago and more than 15 minutes for the doors to open. Cookies were missing from the menu.

Flight was 2 hr late but at least I was upgraded to first class

The flight was delay roughly 90 minutes. Once we arrived at O'Hare, we sat on the tarmac for another 90 minutes. I understand that O'Hare is under construction however they need to figure out a solution as every incoming flight I have been on has been delayed coming to a gate.

We were stuck with no gate upon landing for 90 minutes. Unacceptable.

Better seats, allow us to upgrade, terrible website, poor telephone service, better equipment

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

Avianca is not what it used to be. So disappointing

It was horrible. My experience with Avianca. I didn’t know it was Pakistan international Airlines but anyway, whatever it is it is bad horrible you guys need to upgrade everything in those planes. And you guys charge $130 for a carry-on did they wanna let me in with my carry-on that I travel everywhere with the luggage you guys are such a dog thank you

why did we have to go through security mid flight
