Pros: "Movie options and healthy food"

Pros: "Economy tickets this trip and seated in Row 13 wasn’t too shabby! But passengers need reminding that airplanes deboard in ORDER.. a seat 15 need not shove in front of my 12 year old son.."
Cons: "Late flight and too many dogs who CLEARLY aren’t for therapeutic reasons, but personal.. and NOT well behaved ( barking & jumping .. and on ME, btw..love dogs, have 2 myself but my expectation is a dog in the plane with people ought be ofthe best behaved variety.. screaming babies need Benadryl, parents need to be notified of this, because we ALL pay the same price for tickets and need not be subjected to an acoustical assault for 2/4 hours of a flight ✈️."

Cons: "N/A"

Pros: "On time."
Cons: "Slow boarding and deplaning."

Pros: "Nothing."
Cons: "Put on an American carrier despite having booked with Alaskan. Told the wrong gate. Then told the incorrect boarding time at the correct gate. Missed flight due to gate keeper. Had to gheck my back on the next flight despite ample room to carry on. EVERYONE that works for American Airlines is incompetent, rude and terrible. I WILL NEVER FLY YOUR AIRLINE AGAIN. Your company should be sold off and every employee fired."

Pros: "The crew is consistently on point ! Accomadating , friendly and warm !"

Pros: "Boarding was efficient, seat was comfortable. I appreciate that food and drinks were offered often."
Cons: "One particular flight attendant purposely ignored me when I tried to ask for cream and sugar for my coffee which she did not offer when handing out drinks. Then she looked right at me twice as I tried to give her my garbage which she was collecting, but she ignored me again and left me holding my garbage until a different flight attendant came much later and took it without incident. It made me wonder if it was because I looked Asian- she was helpful and polite to the white women next to me. I was polite and was not being difficult in any way. I'm half white, but was often treated like this in Illinois when I was growing up. She should have been professional and if she had I would have rated the trip as excellent."

Cons: "Barely any free snacks, aside from water. Everything either needed to be paid for or was advertised in a way that eventually got annoying and overwhelming. I felt less like I was on an airplane and more at one of those promotion things where you have to sit in an uncomfortable chair for three hours listening to a guy in a suit talk about boats before you can get a free fast pass ticket to a ride at Disneyland."

Pros: "I like a lot the treatment"

Cons: "Taco"

Pros: "The fight was very professionally carried out."

Pros: "The crew and the comfort plus seat"

Cons: "Taxied at ORD for 45 minutes waiting for a gate to vacate."

Cons: "Smooth on time flight"

Pros: "Nothing."

Pros: "The seats were ok."
Cons: "The flight was delayed over 3 hours so I missed my connection in Chicago to Seattle. I’m now stick in Chicago overnight and have to be on a 6 am flight tomorrow. The Delta staff at LaGuaurdia was extremely rude and not helpful at all. Hate Delta......"

Pros: "Flight left on time"
Cons: "Gate crew had trouble identyfing boarding pass on their computer. Difficulty getting on plane"

Pros: "Amazing crew and clean cabin."

Pros: "I loved the flight attendants and the desk staff everyone was so friendly and made me want to travel delta again."
Cons: "Delta doesn’t offer military spouses free checked bags and I found this out at the airport. It was disheartening, but at least it’s Delta and not the airline that is supposed to represent America."

Cons: "Plane journey awful. Speaker had a loud buzzing noise all the time so never heard a word bad landing. Rattling plane Very cold."

Pros: "Clean plane, the seat felt roomy. Smooth ride and the captain communicated clearly."

Cons: "Small aircraft"

Pros: "Staff, service, options"

Pros: "As usual great staff and awesome entertainment/connectivity"
Cons: "Due to weather & maintenance flight was delayed for IFR release & fuel temperature gauge issues. Staff was very helpful. Would have appreciated a drink voucher. Some unprofessional passengers took their frustrations out on the flight attendants."

Cons: "Over an hour delay before boarding due to supposedly bad weather. Because flight was overbooked they were offering $400 gift card to change to standby on another flight. If you didn’t make that flight (evening), you’d be confirmed on a flight the following morning with one stop in Detroit (we booked a nonstop to Chicago). Uh, no thanks. Then to top it off, we’ve landed and been told that it will be at least an hour before we can deplane due to no availability at the gate (it’s 1145 pm right now). All this plus their new policy of not allowing us to select our seats because we bought the cheapest tickets. Really Delta? You go ahead and cater to the rich and I’ll choose to fly with another airline."

Pros: "Crew friendly"
Cons: "Middle seat with no option for me to move"

Pros: "Movie"
Cons: "Break downs again... At least this time they found another plane."

Pros: "Flight attendants were pleasant."

Pros: "Friendly service, comfortable seat, on time, no issues."

Cons: "Everything"

Pros: "The crew was great"
Cons: "The flight was 4 hours delayed"

Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."

Pros: "i liked that staff and crew were very communicative and pleasant."
Cons: "one crew member didn't show up and caused delayed flight."

Pros: "Flight was on time. Boarded quickly with no fuss."

Pros: "Flt on time, very nice and friendly gate agent and flight attendant"

Cons: "Too tight and seats not comfortable."

Cons: "Delayed"

Pros: "The Delta people were solicitous, efficient and brilliant the whole way through. We had not a bit of trouble. Our first class seats were comfortable, but with the supplied blanket, pillow and poor air conditioning it was a hot flight. The cabin personnel were wonderful as per usual, and my tasty gin and tonic soothed any discontent. I wish I could fly this way all the time!"
Cons: "The private contractor handling wheelchair assistance was terrible. A Delta employee theorized that they do not pay enough to attract and retain personnel. Our pre-arranged chair was not there, multiple calls by our Delta assistant finally got us a ride to the chair holding area, but after about 45 minutes we gave up and shuffled off to the security area on foot. Thank goodness my hubby is mobile enough for that to have been an option. When we abandoned our wait we were still 4th in line for an attendant to push the chair. If Delta has any responsibility in this it would be in the retention and compensation for the private contractor."

Cons: "The delta studio didn't work with Android 8"

Pros: "We were traveling with a toddler and infant but put in different row because the tickets were purchased separately. Gate staff promptly put us together and even bumped us up to delta comfort. Was a very pleasant trip. Thanks delta!"

Pros: "Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league."

Pros: "Airline stewards were very friendly and pleasant."
Cons: "We booked with Delta, but were put on Air France. Even though we had our boarding passes in hand we had to wait in long, slow line for baggage tags because they would not print from kiosk. There was minimal Air France staff on duty serving thousands of passengers during busy season (July). While the lines grew larger, the staff was reduced from 4 to 2. Another long, slow line for customs, another long slow line for security=Charles De Gaulle airport was awful. We arrived at the airport 4 hours before our departure time and got to our boarding gate with no time to spare."

Cons: "Very uncomfortable, seats did not recline and seats way too close together."

Pros: "Entertainment options weren't bad. Most of the crew was polite other than one flight attendant who seemed ambivalent and unhappy to be there."
Cons: "Three hour+ flight and just one tiny bag of pretzels? And no lemon or lime wedges on the beverage cart? Plus, I have to pay extra for one checked bag. I will only fly Delta if I have to in the future. Subpar airline."

Pros: "The crew was incredibly helpful assisting my last minute boarding needs. Staff was friendly and polite."

Pros: "I was notified about the delay via text before I left for the airport, which was nice. I would not have checked my email."
Cons: "Delayed for over 2 hours. I have never flown Delta before this flight and it wasn't a great representation. The flight attendants were nice but I was in a seat near the engine and it was making really weird noises. I fly almost every two weeks, so I'm used to engine noises but this was one of the loudest/most rickety sounding flights I have ever been on.. and I have flown Spirit a few times. It just didn't feel safe. Landing scared me a little too as I have landed in O'Hare countless times and have never flown so low to the highway upon entry. It felt like we were only a couple hundred feet above the cars."

Cons: "Unnecessary flight cancellation. I had friends taking the same flight at the same time at the same airport from different airlines and they came through for their customers. I received no consolation it assistance with overnight accommodations."

Cons: "Landing"

Pros: "Everything was excellent"

Pros: "Comfy seat, great entertainment options"

Pros: "seat was basic. prefer having tv screens in the seatbacks as opposed to using my tiny phone as a viewing screen."
Cons: "prefer having tv screens in the seatbacks as opposed to using my tiny phone as a viewing screen. only food available besides pretzel was pay food."

Cons: "Try to be on time!"

Cons: "If we had access to the WiFi to watch shows earlier like United does, that would be nice."

Cons: "The service and courtesy of the staff wasn’t great."

Cons: "Rude staff, not willing to help"

Cons: "Poor they lost my luggage. They did not allowed me to take my suitcas whit me because the plan was too small. I never travel again whit amercan airlines"

Pros: "The jet"

Cons: "No advanced seat assignments unless we paid $100 per person?! Recently flew Delta on same equipment (A321). Delta had in-seat entertainment & adjustable head rest"

Cons: "Waited on the tarmac for over an hour before departure with very little explanation."

Cons: "There was no entertainment at all, and pretzels are gross"

Pros: "Loved the seat back lcd entertainment"
Cons: "Not accepting Apple Pay. Who wants to dig out the wallet."

Cons: "Nothing..."

Cons: "delayed/not on time"

Pros: "Loved the exceptional kindness of the staff"
Cons: "Lack of movie or music"

Pros: "We were rerouted through Philadelphia."

Cons: "No audio in business. No working electric outlet."

Cons: "No wifi, no personal TVs"

Pros: "Good entertainment"
Cons: "Bad organization during boarding"

Pros: "Very nice staff"
Cons: "Nothing"

Cons: "Delayed a total of four hous!"

Pros: "NOTHING"

Cons: "Think it is ridiculous that I had to pay so much to select a seat ahead of time, and it was just a regular seat. I can understand for extra legroom or exit row, but for a regular seat, that is ridiculous. Then there was a fee to change priority boarding, so I could ensure I was able to have my carry-on with me, instead of risk having it go underneath. Unable to use the entertainment, as I was unaware had to use my own device, which I had not set up in advance."

Pros: "Comfort"
Cons: "Nothing at all"

Pros: "It is good"

Cons: "No tv on seat. Those dumb comedy tv show"

Pros: "delayed at both sides with very little announcements keeping us updated"

Pros: "Friendly staff Smooth ride On time"

Cons: "Always delayed"

Cons: "Got cancelled"

Pros: "very smooth, ontime ride.. kool"
Cons: "everything was ok"

Pros: "Delays caused a little stress but all in all a good experience."
Cons: "Late arrival to DCA."

Pros: "The TIMING AND ATMOSPHERE"

Pros: "It was five star all the way."

Pros: "Service, clean aircraft, I felt AA cares about me"
Cons: "Changing gates before boarding"

Pros: "It was fine. I was comfortable and I slept throat most of it."

Pros: "Not much"
Cons: "We sat on the tarmac for an hour after we landed. Missed my connection, no other flights that night. It wasn't even 10 pm yet."

Pros: "Everything was very professional."

Pros: "Boarding was smooth"
Cons: "It was fine"
