I love my entire experience. What I love most, was the friendliness and helpfulness of the staff at check-in and that of the crew on the flight. Their Customer Service was paramount.

The flight crew was extremely hospitable, though there was a lot of turbulence, they made it a good experience. The only negative was the inflight experience for economy class. There wasn’t any, or at least non that I was aware of.

I liked the friendliness of the employees at the airport

I liked the extra leg room in Caribbean plus. Worth the extra money. The food could have been more balanced, there was no salad or veggies

The Flight itself was smooth and uneventful. The crew was polite and caring. I used the Lounge in Piarco and the service was STELLAR

Crew were quite friendly. Food was very poor considering the price of the ticket and the flight time. Could not charge my phone due to USB charger not working..

The food wasn’t good. Need better food. There wasn’t any entertainment.

STEWARDESSES WERE AWESOME! The food could be a bit better. Rice was SOGGY with gravy and the chicken was RUBBERY.

I was treated well in first class. I have no complaints. I will definitely fly with my favourite airline again this year.

There was no music on the flights unless you came with your headset.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

Friendly flight attendants, smooth 8-9 hours flight. Economy seats are small and uncomfortable as usual.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Flight left early and arrived early. the whole trip was excellent.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Everything was great. Great service, excellent communication, and early arrival

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

No entertainment yatem in flight at seat 51H. Would not shut down either leaving a self moving and openin and changing menus with changes in colors,images brightness levels sort of the type when you get sleep deprivation and image overload when being tortured during an interrogation. 8 hours worth of it. Unable to place backpack underneath seat on that chair. One female stewardess was excellent as she gave up her carryon's space for my backpack but the rest of the iberia crew were very sharp an chtting during the whole flight. The plane did not have hot water so nobody had coffee nor tea. The plane was not up to par to be flying.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

Nice modern plane. Can use your own device for entertainment. Get a snack on the plane.

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

The flight was delayed leaving Miami. When we arrived in Charlotte, we were unable to park at our scheduled gate. We had to wait another 30-45 minutes before we could park at a different gate. All in all, we were delayed by almost two hours arriving in Charlotte.
