Great customer service. Safety and cleanliness. Fly delta.

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: "Nice crew"
Cons: "No leg room for 6’6” person."
Pros: "Average flight. Crew was polite."
Cons: "On time performance. Barely made my connecton, because of flight delay. Seems like only 1 in 5 flights are on time according to flightaware.com."
Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Pros: "Everything! Thank you"
Cons: "Nothing. Thanks"
Cons: "Food really bad on both segments."
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."
Cons: "N-S"
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: "Entertainment was good."
Cons: "The crew was very rude."
Cons: "The wifi wasn't strong enough to download the app to watch movies on the plane."
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: "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: "Very comfortable plane, 4 snack choices, friendly crew."
Cons: "It was all good, except that the charging stations were difficult to figure out since they were out of sight under the seats. I had to have the flight attendant plug in my charger."
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: "Short flight with great views"
Cons: "I was not asked to check my bag, but there was no space for it so I had to take it back off after everyone boarded. No drink or food. Ground crew forgot to get bags at end of fliggt for those of us who checked at the gate. Had to wait quite a while."
Pros: "Nothing!"
Cons: "Racists bastards!"
Pros: "Lufthansa is a great airline."
Cons: "Food was so hot that it was difficult to remove the packaging to be able to eat the pasta.... Desert was ok, brownie was real hard and too sweet...."
Cons: "The least leg room in any flight I’ve taken. We had requested vegetarian and the flight from Frankfurt to Nairobi gave our meal to other passengers.they told us we had to eat the best dish or nothing. This on an 8 hour flight."
Pros: "Staff was extremely nice and helpful"
Pros: "Very smooth flight. Everything was perfect."
Cons: "Check-in Seattle was ill organized and folks cut and groused"
Pros: "The crew was friendly"
Cons: "Maybe not have my luggage lost and get rebooked to a later flight for no reason"
Pros: "Crew were great. Very friendly & helpful"
Cons: "Lufthansa really need to serve something better than high school cafeteria grade food"
Pros: "Crew were friendly, boarded promptly"
Cons: "Food could have been better."
Pros: "Tv screens, free beverages, frequent service"
Cons: "The single most cramped and uncomfortable flying experience of my life. The chair in front of me recliner lined to 4 inches in front of my nose. Couldn’t move legs or arms for 10 hours because it was so tightly packed. I couldn’t believe it was legal to fit that many people that closely together."
Pros: "My seat was next to bathrooms when everyone start using it start smelling too much very uncomfortable sitting there. Food chicken was very salted, they run out of drinks 10 hours flight dinner served at begging no snacks or anything till 2 hours before landing"
Cons: "At least air fresheners in bathrooms or something better so passengers can sit comfortably"
Pros: "The flight attendants were friendly. The seats were new. The movie selection was good."
Cons: "The scrambled eggs for breakfast appeared to be powered eggs, or overcooked eggs. The storage bins for the luggage were very small for the middle seats (aircraft was an Airbus A330-200). After several hours of flying, there was trash in the aisles and on the toilet floor. The toilets were dirty and not cleaned. Finally, the toilets ran out of paper towels and tissues with 3 hours to go in the flight, and they were never refilled. The flight attendants put a roll of toilet paper next the sink to use for your hands."
Pros: "Lufrhansa is a fantastic airline"
Cons: "The seat pitch and width were too small."
Pros: "flight attendant found me a seat away from the screaming babies."
Cons: "I was surrounded by about 6 babies. This is not acceptable for a long flight! I would like to have options as to where I sit. There should be a baby section where families pay more to be in a section on their own!!"
Pros: "We purchased seats with extra legroom. They were well worth the extra cost as we were very comfortable."
Cons: "Very bad food"
Pros: "I always had a great experience with Lufthansa."
Pros: "Good plane and service"
Pros: "Crew was very attentive and efficient. Flight was ready to leave on time but was delayed due to security concerns at Sea Tac airport; even though the flight arrived on time."
Cons: "I did not have a problem with anything."
Pros: "Food was ok. Beer offered at no charge. Lots of entertainment options"
Cons: "Plane was HOT no air and economy was unbelievably cramped and uncomfortable. 9 1/2 hr flight was torture"
Pros: "Staff were nice and friendly."
Cons: "The plane was dirty. The seatback was not clean, and the tray table was stained. The 9-hour flight did not have any USB ports or outlets for charging. The touchscreen did not work well, and my seat would not move forward or back without me pushing or pulling it. This"
Pros: "It was an overall good experience. Very well organized. Since both legs of the flight we're half-empty, it was easier on the crew too. They were nice and helpful. Everything very clean. Entertainment choices were good. Had an excellent entertainment system."
Cons: "Food was kind of bland."
Pros: "Crew is very friendly, seats are extremely comfortable and good room overall, comfortable flight."
Cons: "Hi, To be honest, it was embarrassing to serve that dish on such a major airline. Chicken with bbq sauce and corn or something like that. Was distasteful I couldn’t take more than 2 small bites."
Pros: "The Entertainment, the Food and the nice and friendly manner of all personell."
Cons: "Nothing."
Pros: "Such great personnel in the air - can't say enough how much I appreciated them."
Cons: "The airline as a whole, however, encourages you to book with them under the reasonable assumption that connecting flights with Lufthansa will be achievable. Now that I've seen Frankfurt, There was no way they could actually expect any of us to make our connecting flights. And they offer no compensation. When I did get another flight, it was terribly delayed. Talking in line with regular European travelers, they said they expect it. Also met several fliers at the service desk attempting to connect via entirely different routes, all having the same experience."
Cons: "Crew was not nice at all. They would skip us along the way while serving others, or even drop ice on us, and never said sorry once (instead, they would say it's only ice, or if I want 2 since they skipped me already twice when serving tea unlike the passengers around me on both sides). We paid nearly $6k for the 3 of us, but the crew made us feel as if we paid nothing. The entertainment system did not work well, and most of the time the movies refused to play. We were always suggested to restart, and were not even given free access to internet as an alternative. No one ever apologized for anything in the entire flight, it felt like this flight was a favor."
Pros: "Flight went smoothly boarding was a little delayed."
Cons: "Getting to gate 10 minutes after boarding time and no one had boarded yet."
Pros: "Everything was generally good and normal"
Cons: "Except the plane was roasting and had no vents"
Pros: "Service , on time"
Cons: "Munich airport should be improved far more. it took more than 20 mins to find a toilette. they should install more toilette for the travellers."
Pros: "service, care for my 85 pound dog and his kennel while traveling halfway across the globe! Thank you! Flight was smooth, services on board excellent."
Pros: "Aircraft crew was decent."
Cons: "Seattle to Frankfurt aircraft was the dingiest and most crammed aircraft I have ever used on an international leg. The seats were tiny so much so that some other passengers were not able to fit in! The lighting was gloomy, restroom dirty within the first hour of the flight, no space to keep any magazine or books on the back rest of the seat in front of you, etc. Overall - such a bad experience. Not expected from Lufthansa, especially as I have had great experience with Lufthansa earlier."
Pros: "The view - flying low over the northern extremes of Canada was superb. Thanks to the pilots etc."
Cons: "The flight was late arriving at Frankfurt. I requested a notification to my connecting flight. Crew member frowned, turned away and in formed me, "We don't do that". I ran to the Connecting Lufthansa flight and barely made it on time."
Pros: "Boarding was done very quickly. Unlike the norm nowadays, people weren't cramming every single inch of space in the overhead. In addition, the flight wasn't full so my travel companion got to enjoy a full row to himself while I enjoyed an empty seat next to me to stretch out. The food was very good. The staff came by quite a few times to offer orange juice or water. The entertainment syren was excellent. I watched four full movies on the trip and have in mind at least a couple more for the return leg."
Cons: "Not a thing."
Pros: "Lots of room on a 747 - Lufthansa will probably retire them all soon. They handled my special meal request online and loaded the meals on the plane."
Cons: "The crew didn’t bother to confirm who had requested the special meals, and they perhaps were confused by the size of the wide body rows, so they served my dinner to the passenger in the window seat (seat K) instead of me (seat H) By the time I realized what had happened, my row mate had eaten half the meal. The crew also rammed my knee with a beverage cart while I was dozing. Not the best showing ever..."
Pros: "service, good quick flight"
Cons: "late departure in Frankfurt; high noise level of the Embraer plane;s engines; failing AC in the cabin"
Cons: "There was light turbulence in some parts during the flight but the captain never turned the "fasted hour seatbel on" sign which was strange."
Pros: "The crew were very helpful and polite. The seats had plenty legroom. The food was excellent, and entertainment was also very good. Most importantly, there was no delay."
Pros: "Flight attendant was very helpful. She went out of her way to bring me a special tea. Large selection of entertainment."
Cons: "Food could've had more healthier choices. Also, kid-friendly food would've been a plus. Not enough leg room. Headphones were only working for one ear which is really bad for the ears. Air conditioning was really turned on really high and gave me a headache and the sniffles. I started throwing up during landing time. Horrible."
Pros: "Nice airport"
Cons: "Too cramped. Pay for all food and drinks. Cheesy! Sad!!"
Pros: "Our attendents were clearly focused on our needs. Efficient and still very human and kind. A real treat."
Pros: "Lufthansa service"
Cons: "No entertainment"
Pros: "Lufthansa is one of few airlines in Europe with pure class and excellent service. Even in economy!"
Pros: "COMFORT AND ENTERTAINMENT WAS BEST"
Cons: "BOARDING SLOW CREW A BIT RUDE"
Cons: "A kid next to me keep shifting and kick me and nudge me all the time. His dad was trying to stop him from moving too much but couldn't control entirely. I kept waking up"
Pros: "Lufhansa did a great job. During flights, everything was good."
Cons: "Security check in Frankfurt was terrible, violating all human rights in every possible way! Please don't tell me that it is for passengers safety; such a humiliation cannot be justified by any reason! Since Lufthansa uses this airport for the most of their flights, I would not fly with this company anymore"
Cons: "We were told by the Delta baggage handler that they strike one day each quarter. This would have been helpful information before we booked our flight from Kayak. We had to delay our honeymoon by 12 hours and fly into a different airport. Delta was great though and the Luthanza agent who rescheduled us was also great."
Pros: "Most of the aspects of flying"
Cons: "There is a fair amount of room for improvement when it comes to Lufthansa airplane food"
Pros: "Check in smooth and professional. Please change places with Asia air so you are in front of rather than behind the hoard of people."
Cons: "On my flight from Seattle to Frankfurt I had one stewardess repeatedly skip me. She was a bit older. I thought after the first overlook she would take extra care but did not. This resulted in me having to ask the crew to repeat their previous steps just for me. "Hi, I know you are serving coffee but I wanted red wine". She was a bit clipped about having to repeat steps but what was I to do? She never looked up enough to see my hand and clearly didn't look at my face. She also didn't pick up my hand towel. I essentially had to rely on the rest of the crew but the care from this lady started to feel purposefully negligent of me. The rest of the staff was friendly and efficient. I also thought we were supposed to get an appertiff...one was never offered. Couldn't check in online. Was fine once I got to the countr but could you trade space with Asia air? It makes sense to have them at the end as they have a huge hoard of people it would be nice not to have to go through and several spots to check in. Check in at the desk otherwise was smooth and professional."
Pros: "The crew was especially great!"
Cons: "I had paid for an upgrade to sit in the front of the cabin with extra legroom (row 14A). When I boarded a man sat it my seat. He had not paid for the upgrade, but the crew let him stay in my seat. I had asked him to social distance but he continued to sit right behind me bo matter which seat I moved to. He argued with the crew until they gave up and let him stay. They did not check his boarding pass or ask him to move to his assigned seat I found a different seat away from him but I don’t see the point in paying for extra legroom when the crew let’s people who haven’t paid for it sit it those seats. I felt harassed by the man and was very uncomfortable the whole flight. I am considering my next step, I think I should at least receive a refund for the upgrade I paid for."
Pros: "Due to business I travel allot so I deal with allot of airlines. This is by far the best airlines I have used. Excellent crew and airport staff. I don’t think words can express how satisfied I am with this airlines and airport. The nicest people and great service. Clean and modern aircraft. Going to try flying only with KLM from now on."
Cons: "Nothing"
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: "Crew good and seat OK but not exceptional for business class"
Cons: "Food was average - main course could have been better. Range of movies ok but not great"
Pros: "Yes"
Cons: "Everything was good"
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: "Crew was helpful and food was very good"
Cons: "There was no entertainment on the flight from Vancouver to Amsterdam and this on top of a two hour delay in taking off which led us to have to literally run to our gate in Amsterdam to make the connection to Mumbai"
Cons: "Late departure. Rush to connect."
Cons: "The air conditioners fan was bad and they had to fix it in London which took over 40 minutes off travel time...we arrived much later than expected in Lagos"
Cons: "Flight on time would have been good when you have a late evening arrival. Long wait for luggage at Birmingham airport."
Pros: "Amazing services .. on time just exactly .. I feel really happy onboard KLM ❤️"
Pros: "Seat space a bit tight . I should have upgraded to more leg room . Next time!"
Pros: "Lovely crew, very helpful"
Cons: "N/A"
Pros: "Cabin Crews was extremely good and hospital. Transfer point staff buggy / wheal Chair was good and second to none."
Cons: "Transfer point needs upgrade."
Pros: "Smooth and faster than expected trip. I felt free to get up and walk around on this long flight. Food was good. I sat in seat with extra leg room for the first time and it was worth it"
Pros: "Boarding agent extra effort to improve my seating!"
Cons: "Food amount less than expected."
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: "Amsterdam airport and Rome airport were as breeze to navigate, even only knowing English"
Pros: "The crew was efficient. Flight left on time. Food and wine served."
Cons: "No entertainment."
Pros: "Everything was clean and well organized."
Cons: "The flight was delayed 1 1/2 hours."
Pros: "Nice flight ...was comfortable travel ...good food.Thanks"
Cons: "No such things"
Pros: "Decent meal (warm Pasta all'arrabbiata), nice little muffin for dessert and standard drinks (coffee & tea were a bonus, as they didn't serve any on a similar flight, from Barcelona to Amsterdam), friendly cabin crew."
Cons: "Poor timing - no reason for a 40 minute delay at take off (plane was fully boarded in time) Old aircraft, shabby, dirty and cramped seats. Coming from my connecting flight from Barcelona, I could clearly tell the different in the quality (and cleanliness) of the aircrafts."
Pros: "Smooth boarding, clean seats/plane, nice small aircraft (2 rows x 2 seats each), surprisingly spacious (more legroom than expected - and I’m 6’2”)."
Cons: "About 1h30min delay without an explanation. All other planes in the terminal seemed to take off on time without a problem, without exception (aside from this flight, of course)."
Pros: "Overall everything was ok."
Cons: "Not that I cared at the time but having been asked for a rating on “entertainment” - there was none. Cheap and cheerful really. No extras over the likes of RyanAir."
Cons: "Actually the Welcome on board announcement. The part where they special welcome loyalty program members. I do not get that... I am an explorer holder my self, but really?? so other paying customers are not as welcome. This is leftovers from the older days.."
Pros: "Good information and helpfil boarding."
Cons: "Has to wait in confined area fir nearly 2 hrs before boarding. No restroom or refreshments within that area."
Pros: "Due to lightening bolt strike our pre-Y2K era plane got switched out with a newer plane with modern media delivery at the seats."
Cons: "This caused a two hour delay in boarding and another 30 minutes on the JFK T4 tarmac. Same crappy headphones so it wasn’t the"
Pros: "Lovely staff, good food, great movies."
Cons: "Bag was lost"
Pros: "Everything. A truly faultless experience!"
Cons: "Nothing"
Pros: "Pretty basic one hour flight so there's not much to complain about or praise about. I got some sleep which was good."
Cons: "The crew had their general Dutch aloofness on form. Chatted to one of the stewardesses in Dutch up until she saw I had a British passport then she decided she could only speak English to me."
Pros: "Excellent experience with the cabin crew."
Cons: "Seats on the 777 were too narrow. This 777 had a 3-4-3 seating arraignment, it would have been better with a 3-3-3, similar to a 787 configuration. With the current layout, even with an aisle seat, I was sitting in the aisle. And I am not a large person! The flight was full, so use the 787 and two daily non-stops. For a twelve hour flight, the food was only Okay, could have been better and with a better selection. Meal timing was poor."
Pros: "Cabin Crew was awesome."
Cons: "Entertainment System was not working and no Non-veg food option in flight."
Pros: "Cabin crew very pleasant"
Cons: "Lost our bags, little sympathy from staff"
Pros: "Usual professional and friendly service from my airline of choice for most destinations."
Cons: "Nothing"
Cons: "suitcase didn't turn up, although connection was quite tight"
Cons: "OLD OLD plane with hard seats and tiny screens"
Pros: "Crew was friendly..business class seat was very comfortable and seemed wider than most Nice power outlets great entertainment system"
Cons: "Row 6 in business is after the first 5 rows and Galley and restroom. Very awkward"
Pros: "Everything. Staff incredible."
Pros: "Of the multiple international airlines I recently flew with, I would have to say KLM was by far the best. Relaxing atmosphere, comfortable seating, great in-flight entertainment, although I have the go-go in-flight data/entertainment plan with t-mobile (highly recommended), the flight included a decent selection of movies, television programs, etc. The food far exceeded typical "airline quality," even for an international flight - and included a fabulous little snack box with locally sourced gourmet and specialty items such as chocolate from Belgium, fine cheeses from France, and crackers from England. Drinks = gratis, and crew was exceptionally attentive and went out of their way to make flight as pleasant as possible."
Cons: "Nothing."
Pros: "The crew were pleasant"
Cons: "They didn’t let us board the plane. Allegedly the plane was changed and make us travel by train!! They offered us a compensation but we haven’t heard from them yet. Not good experience at all."
Pros: "The cabin crew, the flight and communication and the cleanliness of the plane."
Cons: "It was really unclear which desk to use at Birmingham airport to check in. It was extremely stressful for a first time flier as I had no idea what to do - the desk location wasn't marked clearly and when no staff were there it wasn't clear that the desk was open."
Pros: "Quick (relatively) flight."
Cons: "Skinniest seat ever. Couldn't even lean back. I now have hunchback."
Pros: "Night flight so no entertainment allowed sleeping"
Cons: "Kosher food could be improved"
Pros: "Spacious cabins, friendly service"
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: "Nice, turbulent-free flight. Food was good, service with a smile. Leg space was OK because Boeing 777s are usually better at this."
Cons: "Flight left over an hour late because of a sensor glitch. It is concerning when a technical glitch happens. But, the flight was smooth."
Pros: "captain was great."
Cons: "Flight delayed ... Myself and three other colleagues didn't have our luggage show up from KLM flight from Amsterdam to Brussels...even though all of our luggage was labeled "priority". Once in customer service line, we looked and saw that many of the other passengers on our flight also never received their luggage. We estimated that 20-25% of the people on that flight did not receive their luggage as they were in line with us for the same problem. Hard to understand how so many pieces of luggage could have been overlooked and not loaded on our flight. Obviously there is a huge gap in their quality system to ensure mistakes like this are prevented."

The staff between IAD and Copenhagen was not friendly

Pros: "The Crew was great. Friendly and attentive."
Cons: "Very small seat. Had a big person next to me and was quite uncomfortable"
Pros: "I really enjoyed the ease of boarding and how smooth the flight went. The airline crew was friendly and the food was great."
Cons: "I wish that I was informed ahead of time that SAS GO LITE flights do not include check-in baggage. I ended up paying $109 instead of $60 because I was unaware that the fees change the day of departure. This upset me."
Cons: "It would be better if the plane was cleaned before boarding. The row where I was seated has potato chips all over the floor. Pls. clean your plane before boarding."
Cons: "Multiple delays. Need to offer back up flights and hold connections for delayed flights."
Pros: "Left and arrived on time. Crew very efficient. Smooth flight."
Cons: "Everything was great!"
Pros: "Very professional crew"
Cons: "One more pass at the end of flight to pick up more trash, to create less work for cleaning crew."
Pros: "Professional and courteous crew"
Cons: "Nothing, was a pleasant flight"
Pros: "Seats ok. Crew very nice."
Cons: "Short flight but entertainment is always a nice thing to have"
Pros: "Plenty of room on this flight. The plane was about half full."
Cons: "Everyone's breakfast was supposed to be an "egg and bacon" flavored wrap of some sort, but there was absolutely no egg or bacon flavor associated with it. The flavor of bacon is very distinctive. This thing's flavor and texture suggested some sort of very tasteless doughy material, with certainly nothing tasting like egg or bacon inside of it. Ugh."
Cons: "Delayed flight - 2 1/2 hrs. No advance info. Departure gate change after check in. No Info at original gate. Unfriendly staff. No apology. No explanation for delay. Food substandard, even for cheap airlines."
Pros: "Quick"
Cons: "Basic travel, if you’re in the US, similar to what you’d find on Southwest. Bare bones but it’ll get you there."
Pros: "Good crew"
Cons: "Premium economy wasn’t as good as others"
Pros: "Newer plane with comfortable seat for coach. I liked the two-four-two seating arrangement. The direct flight to my destination was a plus."
Cons: "Nothing was negative."
Pros: "Efficient boarding process."
Cons: "Seats super uncomfortable, no food for a 3.5 hr flight, just tea or coffee as free drink options."
Cons: "There was no food or entertainment offered."
Cons: "The flight was over 2 hours late leaving Copenhagen, and then we sat at the gate while they unloaded bags to find the luggage of some passengers who decided not to be on that flight. Then it was total chaos at O'Hare. Very few SAS ticket agents who were not prepared to deal with the many passengers who had missed connections. We spent the night on hard chairs in the airport when we could have been re-booked on a flight out that night if they had been at all organized and efficient."
Pros: "I liked the bottle of water in my seat. Thanks!"
Cons: "We could not order vegetarian, so arrived hungry."
Pros: "Made an effort to avoid the turbulence."
Cons: "Bumpy ride."
Pros: "Good service, pleasant staff."
Pros: "Food was good and so was the entertainment on board"
Cons: "Issues with boarding due to problems with brakes so flight was delayed by 3 hours. No food or drinks were offered"
Pros: "Friendly staff"
Cons: "n.a."
Cons: "Not enough characters to express my disappointment."
Pros: "I'm surprised this is called a budget airline (or am I mistaken?!). Anyway, everything was great. The entertainment options were limited compared to Turkish, Emirates, Lufthansa or Qatar, but enough for a 7 hour flight and then some. Also, I liked that there was a bottle of water on each seat for people to hydrate. Very important, and I haven't seen any other airline do it."
Cons: "Nothing stands out really. I'm likely going to fly them again."
Cons: "The flight was cancelled."
Cons: "They should really let you know ahead of time that certain seats (like the ones in front of the emergency exit--not at the emergency exit) dont recline. The passenger in front of me reclined her chair all the way back and seeing as I couldnt recline my seat I had very little space and found the three hour flight extremely unpleasant."
Pros: "Plane was quite empty"
Cons: "Plane wasn't in the best shape"
Cons: "They take blankets away too soon so u freeze. Three hour delay and they only give u a voucher to buy a cup of coffee"
Pros: "Boarding should be done like this on all airlines"
Pros: "Technically, since the first leg of my flight was changed I no longer flew this route, but it was through the same airlines and they fixed my issues no problem."
Pros: "Scandinavian Airlines was good to work with in person to fix issues."
Cons: "This was a connecting flight that was swapped to go to Newark instead of DC due to unforeseeable delays in DC. Not bad in and of itself but they only gave me a few hours notice that my flight was changed (email sent at 1 AM on a 7 AM flight) and I lost my already paid for upgrade to premium economy. They couldn't find any record of me having purchased an upgrade when I went to check in on my 5+ hour flight."
Cons: "Delayed, charged even for water:("
Pros: "The flight from Newark to Stockholm was late, so I was late for the flight to Vilnius,had to recheck-in and wait for 6 hours."
Cons: "A very dishonest experience. The booking never made it clear that I was not allowed to check my suitcase and I had to pay € 70 extra both coming and going and thereby paid 1 1/2 times more for my suitcase than for my ticket. I am very disappointed to be 'tricked' in this way and consider it a very dishonest business practice."
Pros: "The cleanliness"
Cons: "I Had checked several times to make sure I had 2 bags included ( standard for US-EU flights) and every time. At the airport I had to pay an extra charge for my second bag which made the flight very expensive and just ruined the whole experience for me"
Pros: "New airbus with good entertainment screenset clean"
Cons: "Delays on boarding (on departing as well as returning home) Damaged luggage"
Cons: "Discovered that I would have to pay 70 euro for my bag check-in. Not fun at all."
Pros: "awfully glad I was on SAS instead of Lufthansa, which had a surprise strike"
Pros: "It was perfectly On schedule, the plane was very clean,"
Cons: "Pilot was not easily understood, boarding was a nightmare"
Pros: "great plane and food and crew"
Cons: "cant pre book luggage way too expensive for bags"
Pros: "The plane was well kept and the entertainment system worked well with enough choice. The crew was average: no problems."
Cons: "The (transatlantic) flight was delayed 8 hours and the only compensation received was 175DKK for lunch. Had to stay in the airport over 11 hours due to this delay and had already had a 16 hour layover from the day before. I realize that unexpected delays may occur, particularly in cases where passenger safety is in question, but delays of more than 5 hours cause major inconvenience and I felt stuck in the airport with my bags and having checked out of my hotel room already. Just compensating for lunch is not enough. In the future a partial reimbursement for the flight, access to the priority lounge or a more comfortable facility such as a hotel would provide the passengers with compensation proportional to the inconvenience."
Pros: "There seemed to be a little more leg room on this flight compared to the flight from IAD to CPH on 6/26/16."
Cons: "The movie choices weren't nearly as good as the flight from IAD to CPH on 6/26/16."
Pros: "The food is great, the flight attendants are great, and the flight is comfortable."
Cons: "There is little legroom unless you are in first class."
Pros: "The Boarding was fast and the Entertainment ok"
Cons: "Minimal Service Southwest style. Not the best international trip."
Cons: "Lost 4 out of 10 pieces of luggage from our group, and damaged one piece. Got 2 pieces of luggage 5 days later, one piece 7 days later, and the last one 9 days later."
Pros: "Easy flight, on time"
Pros: "Punctuality"
Cons: "Gate changes on both sectors, second one was inconsistent, was too far. Can't comment about food as i didn't buy it"
Pros: "Not much to like other than it was mercifully short."
Cons: "Extremely small space between seats. This is the worst I've experienced in 50+ years of flying. I thought I had purchased an upgraded seat for these flights but was seated in the lowest end coach seats. Of I find I was not seated properly, I will demand a refund."
Pros: "Flight not full could stretch out Arrived early yet gate was ready"
Cons: "Printing baggage tags and putting on suitcase and hefting to conveyor belt. Someone there to help us but we are reaching the age where hoisting bags is not smart"

Service missing, for horrible and small portions

Pros: "Comfortable seats, new plane and friendly crew."
Cons: "Food needs to improve. Pasta versus pasta is not a choice."
Pros: "Crew was very nice"
Pros: "Not a lot. Just that the departure was on time."
Cons: "This Business-class seat is a proper rip-off. The only difference from Economy is the in-between seat is not used. No extra leg room whatsoever. Economy from Honolulu to Los Angeles I had more leg room then this one. Unacceptable response from the crew: "that's how it's been the last years"."
Pros: "Everything was fairly mediocre..."
Cons: "They lost my ski bag! I had PLENTY of time between connecting flights and to not have my ski bag show up at my final destination (Munich - which was also a British Airways flight) was pretty bad. This set me back 4 hours after I've already been traveling for 20 hours! BOOO"
Pros: "Both the crew and the leg room are awesome!"
Pros: "Food was good. Intertainment options good."
Cons: "My seat did not recline so I had trouble trying to sleep thru the night flight. Seats too cramped even after updgrading."
Cons: "Long wait at the gate upon arrival at Heathrow."
Pros: "American Airlines is kicking your guy's butts when it comes to comfort."
Cons: "Tiny seat for international flights is nearly inhuman! I became an overnight contortionist sensation whether I liked it or not."
Pros: "Staff were lovely."
Cons: "Old plane with an ancient entertainment system, generally cramped and uncomfortable. Paid for a specific seat but was given a different one."
Pros: "The plane was newly refurbished. Entertainment was excellent. Seat room, or course, is an issue and comfort was a little above average for economy, but the operation was well-run, the food was descent, and entertainment was solid."
Cons: "The screens on the seatbacks could use shielding from oblique angles. If the people in front of you decide to binge-watch movies late into the night, it can interfere with sleep."
Pros: "Kind crew helping a frightened passenger"
Cons: "Terrible, frightening turbulence and illogical birding. Why not bore back of plane to front of plane?"
Cons: "There was a very large group of teenagers that were very loud the entire flight and disrespectful to crew and other passengers"
Pros: "Food was good. Decent movie choices"
Cons: "Plane was older and in poor repair. Our air vents and over head lights had been completely removed for our row - so we could not read or knit as others could. Seats are far to small and close together to allow for any real rest or sleep."
Pros: "Food was great. Sleeper amazing- I was asleep for at least 4 hours"
Pros: "Arrived on time although departure was delayed. Cabin crew was vert friendlyand boarding was fast"
Cons: "Would have been nice if the reading material was not so beat up to match the plane's perfect interior, otherwise nothing to fault at all"
Pros: "Easy flight sequence to get from Seattle to BCN"
Cons: "Could use better entertainment selection"
Pros: "Service was excellent, and the 777 flight was very comfortable. The flight attendants were remarkable. The ticket agents had difficulty rebooking the London to Milan leg of my flight when that flight was cancelled while I was on the way to the airport, but they were somehow able to get me onto an earlier flight than was originally offered. What I gathered was that the computer was not very cooperative. The ticket agents were incredibly helpful during this process."
Cons: "I lost my original exit row seat somehow and had to inquire into it. I think what happened was that while the ticket agents were able to rebook my cancelled London to Milan flight, my seat reservation on the Seattle to London leg got lost somehow. I suppose another passenger may have grabbed my seat during that rebooking process. I noticed the changed seat assignment only after I left the ticketing counter. I was able to get a different exit row seat (but with less leg room) assigned to me by inquiring with the agent at the gate."
Pros: "We liked that the food and drinks were included. The timing of food and lights going off and on were perfect."
Cons: "The take off was a little shaky but it was our first time on this size of plane, so that might be normal."
Cons: "Luggage did not make it to Paris pit on next flight which in turn was also delayed."
Cons: "Quality of food"
Pros: "Let’s face it, B.A has proper service with friendly crew members, offered up grade to premium economy which I normally take and was more than happy to pay for."
Cons: "3 hours on the plain waiting for take off. Cheap sandwich for breakfast."
Cons: "Being late"
Pros: "The flight attendants were all very nice. The flight was on time."
Cons: "I'm told (late) that BA does not subscribe to TSA prep in the USA. That meant going to the TSA line first, being rejected, going back to check-in to know the reason, then back to the standard long line. Once onboard my seat's entertainment system dies not work. 3 reset attempted with no luck. A month ago, on another long haul flight the same happened. Food was very bad. Salmon so overdone that it was hard to cut, overcooked vegetables and some lukewarm mash potatoes."
Cons: "I was not allowed to board, because I was told I needed a Turkish Visa, even to change planes, and may have lost my ticket payment."
Pros: "Crew"
Cons: "Food, artificial not tasty"
Cons: "I ended up being rerouted to LA!"
Pros: "Once the flight was boarding/ boarded it was seamless. The crew were more than happy to meet or exceed your needs with snacks/ meals, blankets and even drinks."
Cons: "Flight was delayed 1hr and 50min and the supervisor was less than accommodating even after my wife and I had told her we had 2more connecting flights this was going to affect. Due to the delay, we spent an additional $211 on flights and spent the night at the airport."
Pros: "Smooth and uneventful flight on a 747 Staff looked very smart and were efficient"
Cons: "Check in queue, queue at gate, seat was not clean, food poor The World's favourite airline is becoming impersonal"
Pros: "more comfortable than the flight from Seattle - more leg room and larger seats."
Pros: "The Chief Purser came over to apologize. At the end of the flight, the Captain came to me to apologize on behalf of the airline. (Too little, way too late.)"
Cons: "I am handicapped and the jetway was broken. British Airways took a bad situation and made it worse! Obviously they had no contingency plans and the gate agents just wan't to avoid any responsibility and started blaming the poor man who had been wheeling me all over the airport. ONLY BRITISH AIRWAYS WAS AT FAULT FOR THIS. Eventually they put me on a lift several gates away and then loaded me onto the platform lift of one of those catering trucks that deliver food to the planes and drove me to my plane. The plane door was shut and they had to bang on the door to have them open it and let me board. As a result, I personally delayed the flight (officially) 28 minutes; in reality about 40 minutes. This was one of the most embarrassing and humiliating experiences of my life; to be loaded on a plane like freight!! Is this how British Airways operates??"
Pros: "Not much"
Cons: "Flight boarded late, left late, making my connection very tight and my baggage didn't arrive with me. Very inconvenient"
Pros: "It was short"
Cons: "Lost luggage - no one cared despite it clearly being lost at check in going down a broken bag shute. Plane was late. BA is losing their upmarket appeal trying to compete with cheaper airlines."
Pros: "Friendly, efficient crew, entertainment & flight info on monitor."
Cons: "Economy seating. Quite cramped.. I would make sure to book at least Premium Economy in the future."
Cons: "Food was unappetizing and down to one choice by the time it got to us in Premium Economy. nothing premium about it."
Pros: "Seattle to London was wonderful in all aspects great service comfort and amenities."
Pros: "Quick flight with no issues"
Cons: "Little cramped."
Pros: "Got me back to the UK"
Cons: "Lack of storage around seat Lack of privacy Felt like a patient on a trolley Heavy handed portion control Club larder stocked with leftovers Poor quality tableware, that was chipped"
Pros: "Great meal service and goodies. Great entertainment, service. I think BA is the best airline to fly"
Cons: "I liked everything!"
Pros: "TV screen."
Cons: "Food."
Pros: "The flight was great."
Cons: "London/Heathrow arrivals had us going to gate A and through all the security and then we found after going through the security check (1 hr) we saw that the gate for Flight to Venice was B gates. We are not young people, but we aren't ignorant of travel. There was a lot of running around on our part with a lot of undue stress, when we didn't have to leave the E gates at all. There were no gate assignments posted when we landed until 30 minutes out while we were running back to E gates. There is no excuse for that, except we didn't know til the last minute where we were supposed to go after asking 2 people. Why the second check for security after the states on connecting flights? Is this new?"
Pros: "Crew was polite and professional, despite plane being absolutely packed."
Cons: "Food was really horrendous. Better off sticking with basics like frit, cheese, crackers, sandwiches, etc. If I pay extra for early seat selection, don't guilt me into switching with someone who didnt, because they didnt have enough leg room and had a bad leg. Situation was such that I couldnt refuse. So ended up paying extra for a really crappy seat. Seating chart should indicate where the metal boxes are that affect leg room in certain seats so those with a disability aren't seated there."
Cons: "After a three hour delay- the flight was canceled. Was able to rebook flight for next day but took eight calls to find a room for the night. It was a bit of a nightmare. Had pre paid for up graded seat but one was not available on the re-booked flight."
Pros: "We got to our destination eventually"
Cons: "Lack of communication. No explanations. Feelings of confusion and abandonment."
Pros: "The stewards and stewardesses treated everyone as the were sitting in the First Class section."
Cons: "The area near the top edge of wall in front of me needs cleaning."
Pros: "Crew and choice of movies were excellent"
Cons: "Loading sucked. They couldn't keep those that are not boarding yet out of the way for those in the back of the plane to board first. Made one comment to the crowd and then gave up."
Pros: "boarding was quick"
Cons: "seats werent that good for sleeping but I managed"
Pros: "Cabin crew were excellent, good food. Nice blankets and pillows, crew allowed 'quiet time' for sleep with no disturbing announcements. At the end of the flight, after people were getting off, they let my airplane-loving son and I look at the 'upper deck' of the 747 and my son got to sit in the captain's chair for a photo."
Cons: "Seats were cramped, no USB or power sockets, older seat-back entertainment screens"
Pros: "Seemed pretty clean"
Cons: "Had to ask for water several times, they didn't come around much (hardly at all). Boarding was a joke, way too many "classes" and two doors that all went into one line--so it was slow. They should just do first class then business and call "seats through whatever" instead of gold, silver, bronze or what ever they all were. All toilets ran out of toilet seat wipes so all women had to sit on dirty toilet seats or wipe them down first, no paper protectors either! Gross! BA used to be the best but am afraid it's not the case any longer!"
