"2hours delayed and didn't give notification right away 🤷‍♀️. I even lost my food to rush to go to the airport. Paid $60 for seafood plate ending just leave it almost halfway on my way to the airport find out the flight was delayed. I wish they have more accurate policy to let passengers knows for any problems about the flight as soon or as early they can"

"I like that I got to my destination safely."

"The TSA screening is absolutely unnecessary. It is dehumanizing and has been proven to be in-effective!"

"Anyone that purchased a Delta 1st Class seat should have access to the Delta Sky Club. My wife and I purchased 1st Class tickets for a Delta flight from SeaTac to Washington Dulles but were denied entrance to the SeaTac Delta Sky Club because we did have an American Express card."

"Really accommodating staff, and on flight amenities. I would fly with Delta again."

Pros: "The seats were very good. The crew was helpful and friendly."
Cons: "We had a connection in Detroit. The flight from Seattle to Detroit arrived about 30 minutes late, and we barely made the connection. Apparently Delta had not told the Detroit-Boston flight to wait a few minutes for us. We did make the connection, but we arrived at the gate with no seat assignment (we had been bumped the day before from our original flight because of a mechanical problem) as the plane was loading. Had we missed the flight, we would have had to spend the night in Detroit and go to Boston the next day. Delta should have told the gate agent that we were coming."

Pros: "Crew attentive, professional, appeared to be enjoying job with full plane."
Cons: "The mew food boxes in furst class taste terrible."

Pros: "Sitting in the exit row"
Cons: "Nothing"

Pros: "Great crew."
Cons: "Mask enforcement"

Pros: "Clean safe comfortable plane seats. friendly staff."
Cons: "A small credit for miles as the Wifi didn’t work."

Cons: "Having cocktails available on-board"

Cons: "The exit row that I paid up for, for leg room, didn't have extra leg room. First world problems."

Pros: "Crew was awesome!"
Cons: "The boarding did not go on time. An announcement about why would have been nice. Still made it on the flight on time."

Pros: "This was a redeye flight which are never the best. We upgraded to first class for a chance to sleep. The sanitizing of the aircraft was beyond expectations. The personal wipes were a plus so we could clean the areas around our seats to our satisfaction. The individual snack bags are a great idea to minimize handling."

Pros: "It was nice that the plane was not packed full."
Cons: "Box water instead of water bottles. The seat wasn’t very comfortable since it wouldn’t recline."

Cons: "The Seattle gate agents never said which flight they were calling and since neighboring gates were boarding at the same time it was very confusing and rather chaotic."

Pros: "Crew was very attentive. I appreciated the extra spacing between passengers."
Cons: "I would have liked to see alcohol served."

Pros: "There was an amazing variety of tv shows and movies. That is essential for long flights like ours was."
Cons: "For long haul flights, I am used to being offered a pillow/blanket, even when sitting in economy."

Cons: "There should not be a pay wall around the internet in today's day and age"

Pros: "Everything from hospitality to the ease of the flight. Captain communicated to put all at ease during this time in which this pandemic has gotten many fearful of flying. Great landing as well."
Cons: "Everything was great!"

Pros: "Crew was great, flight in general was okay"
Cons: "The plane itself and seating was filthy, some unknown substance fell on me from the vent above, there was a bunch of crumbs in the seat buckle that fell out all over my lap when I fastened it. I'm not sure the tray table was wiped down, or at least not very well. The in-flight tracker was completely incorrect, I was on a 4-hour flight and it read 14 hours and counting throughout."

Pros: "Flight was comfortable and smooth all the way"
Cons: "Tastier food options"

Cons: "We weren't alerted there was a chance of delays. Over two hours late."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Pros: "Crew was very friendly and efficient. Flight was pretty smooth."
Cons: "On time departure would have been nice. 2.5 hours late."

Cons: "2 seats and neither tv/entertainment centres worked....unacceptable on a 10 hr flight!"

Pros: "The entertainment was nice."
Cons: "If the screen wasn’t behind the seat. I could hear the tapping of the person behind me."

Pros: "Crew had pleasant personalities.. not stoic annoyed faces"
Cons: "People should wait their turn getting off the planes “Wait until the seat in front of you is empty,” says the elementary school teacher .."

Pros: "Crew was very upbeat and helpful"

Pros: "Excellent service in most every respect! Boarding was easy, accommodations were quite ample, food was great, and the entertainment was plentiful."
Cons: "Slight problem with making my seat into a bed, which wasn't fixable. Movies were good, except for the trailers before and after each, which seemed to take forever! Didn't get the seats my wife and originally booked with China Southern/Delta, but the substitution was quite adequate! Problems with checking in on flights, as neither airline seemed to be able to deal with this split ticket! But they tried very hard to make thing up to us, which goes a long way to making us feel like we are valued customers!"

Cons: "Missed connecting flight because the first flight was delayed by 2.5 hours. I didn’t get the comfort seat I paid for because of this and was not given a refund for it."

Pros: "I think they flew so fast. We could land almost on time even though we departed a hour late. Airplane was new and clean."
Cons: "Boarding was chaos. They overbooked 25? 45? Anyway, they are in panic. They tried to request ppl to take next day flight by giving away 300 gift card etc. the ppl who were told there are no seats upset and arguing at the gate. Flight was delayed for one hour. Once we are on airplane, they are still shuffling seats around, so ppl cannot move forward. Just standing there for 10mins waiting for things to settle. Flight attendants did not give us a headphone. (I have a headphone for iPhone X so I could not connect it to their entertaiment system.)"

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: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."

Cons: "Partner site said it was Aeromexico. First flight was delta so different check bag policy for internal flight that cost me $80. Screw you all"

Pros: "Nothing really"
Cons: "Flight delay further to the 30 minutes additional 20 min due to crew being not there"

Pros: "Nothing, they didn’t care about you or to help, the llady was so rude and unfriendly, this situation ruin my whole trip"
Cons: "I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?"

Pros: "Boarding is easy as always, I like Delta's system."
Cons: "I had a seat by an exit door. I was incredibly uncomfortable the entire flight due to the cold air comin in and hitting my feet / legs. Two coats and a blanket weren't enough to remedy the issue."

Pros: "It was whatever"

Pros: "Almonds"
Cons: "Seat, did not get upgraded"

Pros: "Great service, very comfortable."

Pros: "The service on board is always GREAT! in Aeromexico"
Cons: "The flight was canceled and we were put in another flight next night. But the staff in Buenos Aires run the situation chaotically and made mistakes that infuriated many passengers. They need more training to learn how to say "I am sorry" more often and know how to avoid getting into arguments with passengers."

Pros: "The crew was friendly and attentive, and the flights were punctual. I was assigned a good seat, and I appreciated the meal, as i was going to arrive in Mexico very late. I also enjoyed the entertainment options."
Cons: "I really have no negative comments."

Pros: "Smaller plane, aisle seat with a lot of leg room (5c), smooth flight"
Cons: "Shorter flight so no snacks/drinks were served, although requests were fulfilled."

Pros: "Food selection and quality were fine. I also enjoyed the entertainment options. Seat area was comfortable and spacious."
Cons: "The flight attendants were uniformly rude and nasty to passengers from start to finish. As I boarded, I asked for a piece of art to be stored in the wardrobe compartment. This was treated as an inconvenience. During and after boarding, flight attendants addressed passengers rudely when encouraging them to take their seats in a timely fashion. Later, when my seat mate politely asked a FA to repeat the food options, she asked, "Excuse me?" several times and seemed very irritated to have to repeat the choices for him. Also, near the end of the flight, a pillow was on the ground and a FA asked those seated in my row to pick it up. We responded that it wasn't ours and she said something to the effect of, "Oh yeah? So how did it get there?" (Maybe because someone else dropped it and we didn't notice?) The FAs seemed irritated to serve passengers at all. Each time they passed through for beverage or meal service, I felt like I was imposing on them. I have never witnessed anything quite like it. Makes me wonder why they were all so upset and and felt it appropriate to speak and act disrespectfully toward customers. (Delta, do you have any insights?) I hope they all got a good night's rest after that haul."

Pros: "Good Snacks, crew is friendly, toilet was clean and we arrived on time"
Cons: "Nothing"

Cons: "As a Platinum AFK/KLM Skyteam member I was NOT allowed to use the Delta Lounge. On the flight the meal choice was poor and the staff were not really geared to serving regular clients. The movie choice was poor. I expected better!"

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: "We had a whole row of 3 to our family, so we could put the armrests up & the kids just laid down in our row (on me, & each other) and slept most of the flight. The flight crew was very understanding and helpful with my kids who were just with me on an intl flight "daddy duty.""
Cons: "Since it was a flight from Seoul, Korea to Seattle; it would've been nicer if all the movies had Korean subtitles-- my 4-yo boy who only speaks Korean, couldn't make it through more than 15 mins of a movie because he couldn't understand (of course, some of that is due to age & short attention-span). But he kept saying, "I hate English" in Korean while trying to pick a movie. Also, I'm 6'2"; so while it was nice having the whole row for my kids to lay down in-- I was cramped and uncomfortable the whole flight, even moreso with Delta's seats being closer together than on other international carriers I've flown."

Pros: "Nice food"

Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."

Pros: "15 years ago I told myself not to fly Delta anymore. But these 2 flights Detroit to Amsterdam and back changed my mind. I enjoyed the flight very much and I'm looking forward to the next one."

Pros: "Great airline"

Cons: "Flight got cancelled"

Pros: "Crew was great and helpful despite oversight in my special meal."
Cons: "Special meal request was overlook. I did not mind so much as eating less does some good! It is human to err!"

Pros: "Great crew, comfortable seating with enough leg room."
Cons: "Provide dinner before getting to joburg, instead of a snack. Flight arrives late so dinner would be appreciated"

Cons: "The flight was a bit delayed, but the airline handled it incredibly well. I was put up in a great hotel with good free food and caught another flight the next morning."

Pros: "The friendliness of the crew"

Pros: "Entertainment was amazing"
Cons: "Seats a bit hard"

Pros: "The space at my feet with the chair in front was a bit akward."
Cons: "Not being seated next to small kids. Perhaps they should have a separate section? ;-)"

Pros: "One crew member was very good but all were not very available or checking on people. I had a seat that I purchased and it was very hard to recline I only found out that it did if fact recline it the last hour to hour and a half of the trip! It was a difficult push back to get it to recline"
Cons: "If I knew how to recline my seat earlier. I did try several times"

Cons: "Long haul flight made pleasant by KLM"

Cons: "Lost all our bags so couldn’t ski"

Pros: "Boarding agent extra effort to improve my seating!"
Cons: "Food amount less than expected."

Pros: "Efficient boarding system, clearly signposted. Professional staff"

Pros: "Very attentive crew. Attended to needs immediately. Took a lot of time with each person when someone had something to say."
Cons: "The seat I had with no seats in front of me was very small. Much smaller than the other economy seats because the tray table and video screen were in the armrests. Paid extra for the legroom by ended up losing it side to side. Really had to squeeze into the seat."

Pros: "Crew where awesone and the choice of entertainment was fantastic"
Cons: "Seats way to close together"

Pros: "Wider seat than most business class"
Cons: "Row 6 in business is after the first 5 rows and Galley and restroom. Very awkward"

Pros: "Wide selection of entertainment, food was good."
Cons: "Boarding unorganized, but that may have been more of a passenger issue then KLM"

Pros: "Great smooth flight staff was pleasant and the overall experience was fantastic."

Pros: "It's the best flight I could get for such a low price. But don't expect to to get the best and newest planes around but it's still overall a good experience."
Cons: "Quite bummed the plane didn't have wifi / USB"

Pros: "We love the flight all the way"

Pros: "Nothing"
Cons: "Airlines had no record of our pets flying with. Missed our flight even though we were there over 3 hours prior. Ruined the last day of vacation. Now we are waiting for the promised help in Amsterdam. No one is here. No one knows anything. Feel like crying"

Pros: "Having exit aisle made a huge difference in comfort Crew were EXCELLENT"
Cons: "Food was not very good Tasteless and rubbery"

Pros: "Flight was quick, professional, friendly."

Pros: "There was no flight! So it's one thing that you have to cancel the flight because of fog; but rebooking us the next day on a flight through New York that doesn't exist, was way below the standard of care I would expect from any airline. Apparently, the NY to LAX flight that KLM booked us on, was only one leg of the flight to Sydney Australia; and according to some airline agreement, only Australian nationals are permitted to take that flight! Running around at JFK from terminal four, to terminal seven, to terminal eight, back to terminal four, to get a flight out, was a bit much considering how tired we were – not to mention hungry, since KLM neglected to provide the kosher meals we had requested with plenty of time – BOTH going to and returning from Europe."

"Not the best crew. Extremely annoying with mask wearing. Even when I was eating and drinking they would come up to you to tell you to wear your mask. Extremely annoying."

Pros: "El entretenimiento"
Cons: "Demasiadas mascotas sin posibilidad de descanso. Un gato en ej asiento del frente que no dejó de hacer ruido y dos asientos atrás un pero en la misma situación. Debería tomar más medidas para el viaje de mascotas"

Pros: "The crew and the food were great!"
Cons: "The seats weren’t very comfortable. You could tell the plane was a little dated. There was no WiFi and nowhere to charge your devices."

Pros: "More leg room"
Cons: "Space"

Pros: "Crew asked us if we’d like to move to an empty row to be more comfortable without us even requesting it."
Cons: "Bigger coffee cups? Really nothing to complain about. Everything I would expect from a flight. A++"

Cons: "I was almost forced to stow my luggage in the hold despite me telling the check-in people tjat I had my meds and cpap in the carryon. I spoke to multiple people. Not sensitive."

Pros: "Crew attentive. The delay was due to airport conditions in FCO, cannot be blamed on Air France."
Cons: "Food. For a 2-hour plus flight, from 11am to 1:30pm, we got 20gr pretzel sticks. This is ridiculous. Don't pretend you are not low-cost! Formerly, before the Joon failed (thank God) venture, Air France had real sandwiches around that time of the day on that line."

Cons: "Comfort plus seats need some work. Very thin padding on a hard seat. The leg rest needs to come up higher so you don’t slide down while semi reclined. Nice compromise between business and coach though."

Pros: "Amazing crew and on time flight"
Cons: "None"

Pros: "Crew was great. Seats were comfortable."
Cons: "The airline lost both of my luggage suitcases."

Cons: "Entertainment worked sporadically"

Pros: "Crew was really good, polite, efficient. The aircraft was relatively new and clean (rare for an airline to provide a new craft on an Africa segment). Food was good, seats comfortable. Will definitely make them my airline of choice to the extent that I can cost wise."

Pros: "Yes"
Cons: "Everything very good"

Pros: "cbvghjkl;"
Cons: "mmmm"

Cons: "Baggage check in was stressful"

Pros: "The airplane"
Cons: "Nothing"

Pros: "Very efficient boarding. We actually departed earlier and then landed in Barcelona 15 minutes ahead of schedule. Overall a very smooth experience."

Pros: "The staff..the attentions..food."

Cons: "Long delays to go through security screening and then further delays as the plane was still being fueled at departure time."

Pros: "Very quiet"
Cons: "We were in the last few rows on a turbulent route. The yaw damper constantly overcorrected, resulting in lots of side to side motion for the passengers"

Cons: "My luggage was lost in Paris. Now I need to wait still."

Pros: "We flew with our special needs child without requesting any particular accommodations except for gluten free meals. The gate staff and flight crew identified him and allowed us special bordering that facilitated the process. That act of kindness is a rare experience on our part. Thank you Air France staff!"
Cons: "Nothing."

Pros: "Food was Fantastic, Air France the Best on Air."

Cons: "Airplane really old. Cabin configuration economy was in front of economy plus. Just 1 bathroom for economy and economy plus. Economy plus seats old and uncunfuttable ( more than it should be )"

Pros: "Boarding for BUsiness class was fine. Seating was cramped."
Cons: "As I said in my rating, seating was cramped. Food was mediocre. Crew was pleasant."

Cons: "Crew not only lacked sensibility to understand the purpose of an emotional support dog but kept harassing me about the dog being tied to my seat. At some point a flight attendant even tried to touch my dog, invading my personal space. When the dog rightfully acted defensive trying to protect me, the crew member started threatening me that he would have the dog sent to cargo, the last thing a person with an emotional support pet wants to hear. Extreme lack of professionalism."

Cons: "Horrible Crew..."

Pros: "The cabin crew was very good!"
Cons: "The economy premium seats are very uncomfortable"

Pros: "Charmingly nice crew and involving captain"
Cons: "the delay of the flight, the drinks we had to pay in the lounge, some poeple got a 25$ compensation coupon and we didn’t. The connecting time was about 1 hour and the luggage was not put on the plane to beirut"

Pros: "Service was excellent, top of line Food ,some of the best I’ve had on a airline Seats & pillows comfy But we were in La Première! Also the equipment- a380 was terrific"
Cons: "Only 1 bathroom (toilet) for all of first class"

Pros: "Staff was nice"
Cons: "Very cramped. Poor leg room also with.metal bars under seats that further. Limited foot room. Terrible options in movies."

Pros: "The food, the service and everything else is fine, quite good."
Cons: "However, our baggages were 1 day late. Your missing baggages would deliver to you 1 day later, for some maybe 2 days later...Quite a few people said that it's been always like this with air Aeroflot if there is a transfer flight."

Pros: "Got pillow, blanket, headphone and eye cover"
Cons: "Older plane Very small tv screen Didn't get the bread roll with my dinner. Asked for it but she didn't bring it to me. No usb plug to charge"

Pros: "Absolutely nice friendly and professional crew. Congrats! Nice food, rich and healthy Right in time despite few delay at departure"
Cons: "Just a need to improve entertainment facilities (digital screen, Wi-Fi. ..)"

Pros: "Good service all around, personnel pleasant"
Cons: "Very difficult to find where to register with the flight but this is more tied to the way things are run by the airport"

Pros: "Good on a short flight"
Cons: "Paying for carry on due to weight limit. First time this ever happened!"

Cons: "Business Passngers have to wait in the same bus to board the flight what is the point then...."

Pros: "The time of the flight was great as well as the arrival time and subsequent connections to Paris. Enjoyed the rather full line of in flight beverages!"
Cons: "Leaving late seemingly without reason from Paris - chaotic boarding line in Paris with difficult to hear PA. Seats were ok'ish but than again, it's a 45 minute flight. The sandwich was gross and I'm somewhat known as a person who eats everything!"

Cons: "The leg-space is very narrow The chair is very tiring No entertainment at all Food was tasteless But most surprising was that we were on stand by for our connecting flight. Though we bought the tickets months ago and we got our luggage checked in all the way to the final destination."

Cons: "We were rebooked, which understandably happens for any number of reasons. However, we were not informed or asked about our preference until our luggage was checked through! The staff especially in Chicago where we began this awful experience couldn't care less about our situation. Then AIr France lost our luggage and provided no help in locating them. We had to rely on folks who had friends working in Zagreb Airport to locate them. Air France is incompetent, insensitive and unprofessional. If you have an important trip avoid Air France - they treat you like captives not customers."

Pros: "Not much"
Cons: "Plane late departing allegedly because of cleaning the plane, but why was the cleaning done that late? Also, ground crew remarkably uninformed about what was going on in the plane. Poor communication between plane and ground crew. No explanation from pilot as to continuing reason for delay even after we boarded. Departure time, 1.00 pm, boarded at 1.10, actual departure time 1.45, causing me to almost miss my connection and definitely causing my bags to miss the connection."

Pros: "Flight arrived safely."
Cons: "Air France offered no help rebooking missed connection at JFK due to delay of more than 2 hours in arrival."

Pros: "Good seat near the front."
Cons: "Delayed arrival by 30 minutes."

Pros: "It was clean The crew was very kind Food was very good Flight was on time"
Cons: "Seats were exceedingly close Screens for entertainment were small and game controls were difficult to use"

Pros: "Cabin Crew and food selections were top notch"
Cons: "Seat configuration as a first class ticket was awful. Same configuration as economy class but by leaving the middle seat empty constituted first class. I'm 6'-1" and missed the legroom...."

Pros: "Seats were comfortable, but the sliding action, instead of recline, took getting used to. Food was very good. Snacks available on demand, along with drinks. Complimentary wine with meal was also quite good. Entertainment system was first rate with plenty of options for TV. movies, music, games, etc..."
Cons: "Sitting in the middle two seats in the center of the 777 left me stuck for most of the flight. Got up only once. Wife's feet and ankles were swollen by the end of the flight. Not enough legroom to move much during the flight and not enough aisle space to get around with the plane so full. Have made flights twice as long on the 747 and were able to get up and walk."

Pros: "Food and service"
Cons: "Too many business class seats and the plane is so big it basically feels like flying on coach. You have two seats next to the window so it's exactly the same when trying to get up than in economy class with a passenger stuck next to you"

Pros: "Boeing 777 had a lot of space. Good legroom. Timely departure and arrival, hassle free, safe trip all the way. Enjoyed the red wine; very delicious!"
Cons: "Seat didn't recline. The entertainment unit was very difficult to dislodge and raise to use (We were in the front). Movies were kind of older ones but I had reading to do so entertainment wasn't that important."

Pros: "The crew was friendly."
Cons: "One of the engine was smoking just as we took off. This should have been checked beforehand that it was working correctly. The pilot missed the first landing, was going too fast and had to turn around. We circled the London eye 3 times. When we were actually landing it was extremely bumpy and on the way down the plane was tilting back and forth a lot. They were going too fast when we landed as well, I have never been in a plane that has landed so poorly, and I have travelled a lot and used many different airlines. It was worse than any budget airline I've been on. As we were driving back to the terminal, the pilot stopped short for some reason. Things were not explained clearly. I will not be flying with airfrance again and will be sure to spread the word of this awful experience."

Cons: "Left a little late for no apparent reason."
