Pros: "Amazing crew"
Cons: "I had booked a window seat, the when I went to board, it was changed to an isle seat. I find that I dislike the sole due to the rudeness of people in general and I kept getting hit with purses and such from passing passengers."

Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."

Pros: "Quickly moving through the airport."
Cons: "Take out old planes. It was really run down."

Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."

Pros: "Entertainment was awesome. Although airlines are stingy with snacks, Delta had a good overall selection and very generous."
Cons: "Something that cant be changed overnight, however, there should be a little more Aisle space for folks pass through as my shoulder was getting beat up after every passing person and cart."

Cons: "Cabin was very loud, with jet engine noise. Could not block it out. Seats were not comfortable."

Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"

Cons: "Crew member passing out ear buds ran out and never came back"

Pros: "Nothing particularly stands out. I did arrive safely."
Cons: "First class did not come with lounge access? Drinks were not cold. Bathrooms were falling apart and came with a disgusting odor. Time to retire these aircrafts."

Pros: "Flight attendants were nice based on the situations beyond their control."
Cons: "Flight was delayed for about three hours, due to mechanical issues with the second engine not starting. We sat on the the plane for over an hour and half. Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."

Cons: "Tv"

Cons: "1/12 hours late had to change out equipment"

Pros: "The chekc in person was very helpful."
Cons: "The plane was too hot and the pilot did not accommodate the passengers request. More than just me made the same request."

Pros: "on board entertainment options are really nice... esp to be free. real time luggage updates in early"
Cons: "like to see a bit better snacks"

Pros: "It was great"

Pros: "That I landed safely"
Cons: "1st class was horrible."

Cons: "I have traveled with my luggage plenty of times through airports and the flight from washington to jacksonville, my luggage came back to me cracked and broken. I was surprised that Delta handling was worse than any of the cheaper flights I normally take and will not be checking any baggage with Delta again."

Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"

Pros: "Nice flight and good staff and service"

Cons: "Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this."

Pros: "My flight was canceled but Delta rebooked me on a flight leaving at about the same time as my original flight, which arrived just a little later than originally anticipated"
Cons: "My original flight was canceled"

Cons: "Delayed two hours"

Pros: "same"

Pros: "Delta never used to be my first choice in airlines, but of my recent experience with them has been excellent. The people from the counter to the plane have been professional and courteous. This is why I will fly with them more frequently."

Pros: "Got to my placs"
Cons: "Lol put the two fattest people next to each other"

Pros: "The fact that there were no snakes on this plane :-)"
Cons: "Same issue... there were no snakes on the plane :-/"

Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."

Cons: "There delay"

Pros: "Staff friendly,efficient and courteous. On time. Different snacks. Prompt service. Power source each seat worked."
Cons: "Gate area for flight change filthy. LAX gates 31-38. Garbage overflow with no seating. No entertainment option on flight."

Pros: "The crews were very friendly and everything went as planned. It was a nice flight."

Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."

Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."

Pros: "Everything was great"
Cons: "Nothing everything was fine"

Pros: "The crew and the flight were all very pleasant. Highly recommended."
Cons: "Unfortunately the trip was marred by being stuck on the tarmac for the better part of an hour while we waited for out gate. Even when it became available however, we were forced to wait while ATC sent every other plain taxiing through our route which was clearly visible from our vantage point. Not an issue with Delta per se but nonetheless it left us all exhausted and frustrated."

Cons: "paying extra for leg room and checked bags"

Pros: "lte leaving Houston, cancelled flight back from Atlanta, reset to 3 hrs later, wound up leaving 12 hrs later."

Pros: "Nothing"
Cons: "Being scammed by the Chinese, China Southern"

Pros: "On time departure and slightly early arrival"
Cons: "Airline food is just so inadequate in every way."

Pros: "Rebooked to Atlanta because of a delay."
Cons: "Delta notifications and Kayak notifications were giving me conflicting information, however once I arrived at the Houston airport a Delta representative clarified my issues."

Pros: "I am 6'6" 300 pounds ... So I regularly book first class for trips over 2 hours in length ... Delta remains my #1 choice for both value and overall experience in first class. The difference between Delta and all other domestic carriers is just overwhelming. United and American/US Air could learn a lot from Delta. I could have flown this trip direct on United, but chose to fly through Atlanta on Delta for less money and a better experience from the baggage check to the gate to the in-flight experience."

Pros: ".....delta in Washington was great changed my flight so I didn't have delay !!!!!! Will always use"

Pros: "The crew was super nice, they offer me to change my seat to fly with my sister."
Cons: "The pilot"

Pros: "It got me to my destination safely."
Cons: "Very abrupt service. Not much room."

Pros: "Crew were amazing"
Cons: "WIFI please for the god sake it’s a transatlantic flight"

Pros: "787 seats have better legroom & recliner"
Cons: "Vegetarian food needs lot of improvement"

Cons: "My tray table was dirty. It had crumbs on it. The flight was on time which was awesome."

Cons: "The seats are extremely restrictive and in a aisle seat I had the gentleman sitting next to me with thighs touching and attendants brushing by me as I squished to left to avoid contact with him. Entertainment screen between center seat and window seat so I just didn't even try to look at it and mostly just leaned forward to have a little space. Also another inch or 2 was taken by person in front of me putting their seat back. With such restrictive space why is this even possible??? Flying has become ridiculous and I try not to as much as I can."

Cons: "We landed early but the plane was late 50 minutes into gate. Plane went pst our gate twice, just driving around the terminal."

Cons: "I'm expecting more from AA. We were delayed for 2.5 hr since we didn't have a pilot !!!!!"

Cons: "Speaker volume was too high."

Cons: "Instead of taking my one half of one ounce plastic cup half-full of wine, the stewad, allowed me to keep it. I love common sense."

Cons: "4 gate changes, delayed delayed delayed. UGH. Sirens going off at gate no staff around to turn it off or talk to. Lady at counter very upset with pilot. We had a plane at the 2 gate but no flight crew. Next gate no plane but crew. Who organizes this? American airlines has some work to do!"

Cons: "N/A"

Pros: "On time"
Cons: "Tiny seats, no snack or napkin with the drink. Noise in back."

Cons: "I missed this connecting flight."

Cons: "Too bad you paid$$$$ and they give you pretzels"

Cons: "Small, cramped seating"

Pros: "The flight was on time"
Cons: "Tiny bathrooms"

Cons: "Poor flight. Staff kept the plane ridiculously warm the entire flight."

Pros: "Fast trip!"
Cons: "We were delayed because of a broken tray table and then the broken tray table was mine. But we made it, and the flight was good, so it was fine."

Pros: "The flight crew was very friendly"
Cons: "I wish the flight was longer. :)"

Cons: "The flight was delayed an hour (which wound up being a 3.5 hour delay in total, with all the continual delays that pursued afterwards(, which would have made us miss our connecting flight back to our home destination. We switched flights in order to make it home at a decent hour and not spend our entire day and night in an airport. We arrived home and they did not transfer two of our three checked bags to our flight, thus making it highly inconvenient upon our arrival home with no luggage."

Cons: "The male flight attendant was incredibly rude, kept hitting my arms with his body with zero apologies. No manners when taking food and drink orders. Did not seem like he liked his job and in a customer service atmosphere this was extremely disappointing."

Cons: "Too many delays as usual"

Cons: "Poor seating and lost my bag."

Pros: "The terminal seating"
Cons: "I am a 100% disabled veteran and I was being rushed by flight stewards with no regard to my physical limitations. I wanted to try the kayak route but after this last experience I don’t know if I’ll still with Kayak"

Pros: "The flight was smooth."
Cons: "The crew announced we would not receive beverage service without a reason. Also there was very little air coming from the vents, so not to receive a cold beverage on a hot airplane for a 72 minute flight (should've been 52 minutes; however we were delayed on tarmac) is not logical."

Pros: "Plane was new and entertainment was free. Great service too."
Cons: "American has improved a lot"

Pros: "Everything else was Fine on the flight..."
Cons: "...But having HBO NC-17 available on a public flight is uncalled for. Even though screens employ technology limit viewing from the side, the seats behind can see everything. We were thankful none of our kids were on this flight. Gratuitous sex scenes in abundance. No thanks American."

Pros: "On time. Crew was nice, too"

Pros: "The pilot did a great job flying. Very smooth."
Cons: "The flight attendants were pretty mean and just overall dissatisfied. Apparently we had community water to share? Everyone gets water from the same bottle?? Too strange."

Cons: "Seat in front of me was broken in the reclined position so I had no leg room."

Pros: "The seat pockets were decent, though I like when the magazines have their own designated slot behind the tray in addition to a pocket. Also good there were power outlets. I liked that they didn't skip row numbers, including 13. So if you're in row 22, for example, you know that's literally how many rows back you are."
Cons: "It took 25 minutes from when plane landed until it reached the gate. There was also apparently an issue with the auxiliary power -- the lights went out in back half of plane when we arrived at gate. I prefer having a screen behind each seat, rather than those attached to ceiling on this flight, so that the entertainment can be customized."

Cons: "Plane had no Per-seat entertainment system."

Pros: "Crew we're phenomenal"
Cons: "Great flight and crew baggage claim at Philly needs work"

Pros: "Biscoff!"
Cons: "lack of ent. options"

Cons: "Flight was cancelled and we were never notified!"

Pros: "Boarding process and flight crew were just fine - nothing excellent, just average. The plane was an older model, nothing special. We arrived 10 minutes early but then had to wait 20 minutes for a gate."
Cons: "They had no alcohol and no entertainment on a Transcontinental flight from IAD to LAX. Also once we landed we had to wait 20 for a gate assignment."

Pros: "entertainment displays on the back of every seat headrest. Nice room on Main Cabin Xtra, even with someone in the middle seat."
Cons: "1 of the flight attendants was pushy(older caucasian lady)"

Pros: "Flight got to gate 15 earlier than scheduled."
Cons: "But took one hour to get gate checked bag, which was mixed in with checked bags at bagged claim."

Pros: "Comfy seats, great service, was a smooth ride"
Cons: "my entertainment system wasnt working, the headphone jack was not working at all."

Pros: "Friendly, helpful flight attendants. Flight left and arrived on time, despite being completely full (asking for volunteers to bump). Offered to gate-check our carry-on bags for free to alleviate crowding of overhead bins was fine for us since we already had checked baggage."
Cons: "If you don't pay for the premium seats, the legroom is pretty tight. I'm only 5'8" and I felt it -- if you're 6'+ you better pay for it. This aircraft had screens, but not individual ones so you're stuck watching whatever sitcom replay they pick, although there is a moderate selection of other music. I've been on a newer aircraft with the in-seat power and interactive screens so I know how good it can be, so this was a little disappointing."

Pros: "Crew was nice"
Cons: "I would like to be able to let the passenger next to me to close the shade. He slept , the sun was not in his face ."

Pros: "The staff was so nice and helped me find my way around."
Cons: "Food prices a bit high when compared to buying the same thing outside the airport."

Cons: "Each flight delayed at least an hour"

Pros: "I did like sitting on the left side of the plane. There's a little more room. I feel it's horrible how the airline charges so much and cram so many seats in one air craft. Making it a miserable flight."
Cons: "See above"

Cons: "no food"

Pros: "The flight was on time. It was serviced well by very friendly flight attendants. I enjoyed it very much."

Pros: "The crew was very helpful and kind."
Cons: "Our flight was delayed over an hour and we had a connecting flight to Vegas that we were worried we were going to miss."

Cons: "flight was rebooked to a terrible time, the next day, had to spend over $300 for hotel, extra parking, extra meal, extra day on rental."

Cons: "Cancelled, had to stay in Dallas until next day"
