On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

Everything was as you would expect in coach - fine. Flight was close to on time.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Horrific checkin procedure with neither Delta nor Latam figuring out how to check me in. 4 hrs on customer support with both and both airlines pointing to each other who should do checking. I was not checked in until morning of flight, which for international flight is concerning.

It was a good experience, the flight was a little too long & the food was ok

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

Tough flight with turbulence… I was told by a fellow passenger that it is common. Nonetheless, very stressful. Cordial staff.

Very unprofessional staff in the checking and boarding. There was no space for my carry-on bag, which is understandable for a full flight. However, the rudeness in answering my questions about my bag were unnecessary. Shaming and threatening a passenger to be left behind was something I had never experienced (I am 57 years old and a Skymiles member) before. At a minimum, the boarding staff (Krystal Mejia and her manager Dee) should undergo further training on cultural sensitivity and professional skills on speaking with passengers. Krystal, just because I have dark hair and “look Latina” does not mean I can speak Spanish. Your assumption and threatening words until the very ending of my boarding (door of the airplane) were not only unnecessary and stressful but something that a passenger should not experience before boarding.

The flight was overbooked and the solution gave was unrespctful. I arrived 4 hour in advance in the airport and only after 2hous was possible suggest a different ticket with another company LATAM, I have accepted, but when I was checking in at LATAM the tickets was issued without luggage, what it is absurd since I have bought my tickets including it since the beginning. Due to the timing for the next flight was not possible return to Avianca to claim due to the distance between Both companies Avianca and Latam since were located in different terminals. I have insiste to the crew of Latam to call Avianca to solve it, but they could help they were alleging that only paying a thousand pesos Mexicans ($1,000 MXN) to dispatch my luggage would be accepted and I have no money at all. So I had to beg for others passagens, it was an humiliating to exchange luggage with who was platinum in order to return back the luggage in the connection airport in Brazil (GRU). I have no clue that a judicial process would be taken from my side due the lots of stress in sequence by the non professional treatment with a passenger that was just following everything said by Avianca.. Long hours of waiting until next flight and only arrive at final destine in 6hs later..

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

Cons: "The flight was full and all seats were taken. It means it was impossible to maintain the required and necessary social distancing."

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

they made me check my carryon. There was space in the overhead bins.

It was spectacular. I had basic Economy and was given so much space and their seats lean back so far. Staff was superb, food was superb, everything was superb, Finnair is Fantastic.

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Cold air blew constantly on my legs almost making me numb.

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day
