Airline reviews

Pros: "Great smooth flight, crew were friendly and many movies and shoes to choose from."
Cons: "Seats are tight and not much leg room for the unfortunate ones who fly Economy class. Food was ok."

Pros: "Service was excellent"
Cons: "Carry on baggage size misleading"

Pros: "Movies"
Cons: "Crew was rude to passengers. One passenger asked for extra bread and crew arrogantly commented , we dont give but ok take one."

Pros: "Everything was just dandy!"

Pros: "Amazing food, There were pillows, blankets and earbuds on every seat. Really a great flight overall and I would fly with them again."
Cons: "The only minor complaint was that the seats are so small that when the person in front of you reclines, you literally can’t get out of your seat."

Pros: "Best food I've ever had on an airline! Great flight. Not too full."
Cons: "Arm rests didn't lift all the way up on the plane."

Pros: "Crew was attentive to passenger needs in a quiet way: without fanfare, did all possible to make it a pleasant, comfortable trip. In fact, went out of their way to get me a wheelchair ride to next flight, which I dearly needed"
Cons: "First flight was delayed due to circumstances outside of airline’s control. They managed to get us there and help me with wheelchair, etc to make flight. Great service and kindness"

Pros: "Seats were comfortable and the crew was great"

Cons: "I had a carry-on sized bag which would have fit in the overhead compartment. I was told that it would not fit the Swiss Air compartment, thus was forced to check it at the gate. I expressed my concern that it would get lost (thus the reason I never opt to check bags) and was assured "They are very efficient in Zurich." When we arrived in Madrid, my bag was not at the carousel. I was told at Customer Service that it was on another flight, but that they could deliver it to my Airbnb between 4-7 pm. I had to wait there instead of enjoying my vacation to wait for my bag. The bag did not arrive until 10:30 pm. I did not have my clothes or belongings with me all day. Swiss Air in particular needs to update their overhead compartment regulations, as my bag definitely would have fit there, and could have avoided this entire situations."

Cons: "My special meal wasn’t available."

Cons: "The seats in coach plus and Bussines were terrible"

Pros: "Excellent Service. Excellent food."

Pros: "Most everything about the process."
Cons: "Person in front reclined chair fully and left virtually no room for sitting!"

Pros: "Not very much. At least the staff was friendly."
Cons: "It seems like they always sit me next to the bathrooms. If I'm paying that much for a flight, I don't really appreciate having hordes of people lined up for the bathroom, bumping me constantly. I also don't very much like the door constantly opening and closing, due to noise and the obvious smell. Furthermore, I sat next to a family with 2 screaming babies. Overall, 8 hours of agony. Not a good experience at all."

Pros: "The flight attendants seemed very courteous, but unable to do anything about the situation."
Cons: "We had a family of four sitting behind us. The father yelled all the time. They took up four overhead bins and he was frequently up and down getting things out of the bins. His very hairy large belly was touching my daughters head every time. He and his children punched the backs of our seats on a regular basis. My back was in constant pain and I was unable to do very many things due to the back pain during my "vacation", The flight attendants had to remind the parents that their children could not stand on the seats during takeoff or crawl around under the seats. No ability to change seats or I would have. I didn't have a problem with the other children on the flight, when they were crying their parents tried to do something. However these people brought playdough for their child to roll out or punch on the seat tray and all they did was constantly yell loudly at their children, Well not about the kicking, punching, or crawling around. Just yell in general at them."

Pros: "On time and friendly service"
Cons: "Poor selection of films, cramped seats and mediocre dinner"

Pros: "Airline services and great time scheduling"
Cons: "Upon arriving to Chicago airport the Chicago airport couldn't get passengers off the plane due to mechanical issue"

Cons: "Seat in front of you tilts back and gives you NO room. Horrible!!"

Cons: "Airline lost my flight, no explanation and or apology. Seats were terrible could not move when seat in front was reclined. No economy plus, no reciprocal consideration for gold status on star alliance except for one checked bag free. I will never fly Swiss again"

Cons: "There was a supposed difficulty with my entry in Europe when I tried to Check into Chicago. I thought that I had to cancel my flight. Swiss air representatives had to do much consultation, which took nearly an hour, while I was standing there the whole time. At the end, I was thanked for my patience and told all should be well and not even given a small upgrade for the distress this caused me. Traveling is disagreeable in general now, and personally, even moreso after this episode."

Pros: "On time, efficient, good service, professional"

Cons: "They lost my bag and after 24 hours, still no word on whether it's been located."

Pros: "Very prompt and courteus"
Cons: "Baggage missing for three days. Communication poor."

Pros: "Flight attendants were perfect, sincere, and friendly. Great selection of free movies."
Cons: "I could not open my laptop and do any work once the person in front of me put their seat back. Big time bummer."

Cons: "My flight attendant was rude and condescending the entire flight. I don't appreciated being treated like a moron for asking someone to repeat a question."

Pros: "The flight crew were friendly and helpful. The food served on our flight to Zurich was delicious. We loved the big movie selection which helped pass the time."
Cons: "The leg room was terrible on this plane. If anyone reclined their seats, you were trapped and could barely get out of the row to get up or go to the bathroom. Boarding was a bit like herding cats and everyone was jammed up trying to get on without any orderly direction."

Pros: "Staff were courteous and there was abundant food and beverage service."
Cons: "No child activities were distributed by the crew (like they did for our return flight)."

Pros: "crew"

Pros: "Flight boarding was quick and fast and food was great."
Cons: "Seats had no room and if someone in front reclined the tv was right in your face. Also what happen to having individual fans above. It was so hot I felt sick the whole way and when we pushed the call button no one came had to flag down an flight attendant walking by. We had to ask three more times to get the heat down. Overall it was okay."

Pros: "same"
Cons: "same"

Pros: "Everything else."
Cons: "The selection of movies was not impressive"

Cons: "Nothing. Had a great trip!"

Pros: "It was a great flight!"

Cons: "It was all good"

Pros: "such a big difference in size of aircraft, very comfortable and great crew."

Pros: "Nice crew"

Pros: "Crew was great flight was comfortable however checking in bags and printing boarding pass was slow and also very unorganized"
Cons: "Checking in bags and printing boarding passes were long unorganized lines of people"

Cons: "Overall, I am disappointed in Kayak for listing my round trip flight as KLM, when in actuality, only one short connection of this flight was actually KLM. My itinerary said KLM all over it, but in the fine print it said "operated by Delta." This is dishonest and misleading."

Pros: "Great crew. Very kind and efficient."
Cons: "American carriers seem to enjoy poor seat ergonomics."

Pros: "The crew was amazing and effiecent. Had weather delays, bag got left, but got it the next day."

Pros: "The crew was outstanding and the good choices were excellent"

Pros: "Comfy, nice crew, attentive."
Cons: "Nowt"

Cons: "My bag was damaged in transit"

Pros: "Crew were great"
Cons: "Uncomfortable to sit for eight hours"

Pros: "Friendly staff, so much food/snacks were offered. Good movies available."
Cons: "Nothing"

Pros: "The crew was professional, responsive and friendly."
Cons: "The following experience goes down in history as the worst ever because: we had a 3.5 year old child, and mom and dad seated directly in front of our row. The couple ignored the instructions to move seats forward during meals making it impossible to eat. They placed their luggage in the overhead compartment belonging to both rows, which wasn't a problem if they hadn't proceeded to open and close the compartment every 20 minutes. The 300 pd dad repeatedly stepped on my broken toe while reaching for his luggage, while rattling around and disturbing sleeping passengers. And, sadly the child repeatedly threw temper tantrums without any care or effort of intervention from the parents. In short, they terrorized the surrounding travellers. In contrast, my outbound flight, also had a family seated in the row directly in front. This family was the antithesis, considerate and respectful of their fellow passengers. Susan Laws"

Cons: "Seatback TV is of the worst quality among airlines. They really need to upgrade those. They don’t nearly give enough beverage and water. The gate wasn’t announced till last minute. There was no group priorities when boarding. Process was chaotic. Food was meh. No internet."

Pros: "Entertainment Meal service and quality"

Pros: "Legroom, lovely staff and all round good flight"

Pros: "Everything was as or better than expected. Did not have high expectations, because price was so much less than other airlines. Crew was friendly. Was pleasantly surprised all was good. Was expecting extra fees, (from reading reviews) but had none. Virgin checked bags all the way through, even though tickets were unrelated (and my online checkin said I would have to recheck baggage for second flight)."
Cons: "Seats are small in economy. I was lucky it was not a full flight, so I had two seats. The entertainment system was a. It confusing to manage, but the choices were good. Food was ok; but not worse than would expect."

Pros: "Our ticket was canceled apparently due to an error by the airline. Very unhappy about that. The airline couldn't care less."

Pros: "Good Service. Great attitude of flight attendants..early arrival. smooth flight."
Cons: "despite purchasing 'extra legroom' seats, it was still very, very crowded and tight."

Pros: "Food and service was ok"
Cons: "Delayed at the airport. Very little leg room and hot while waiting to yake off. Entertainment was really bad. Bad screen and sound quality was awful."

Pros: "Crew was very solicitous...food was quite good.."
Cons: "Baggage was very slow in arriving. ..45-60 minutes"

Pros: "Overall comfortable journey"
Cons: "No option to book food option 24 hours before as could check in could not been done earlier than 24 hours before flight. I logged exactly 24 hrs before filled in details which took a few minutes by that time said too late to book special meal."

Pros: "I loved how the airline crew were very accommodating. This was an awesome experience. A+++"
Cons: "I have no complaints."

Pros: "The onboard crew were lovely."
Cons: "Stood at check in for over 30 mins with no staff in sight. Boarding was a disaster. Staff was not prepared nor organized and the crowds were unbearable. Upgraded seats were laughable and not worth an extra $60. Food was mediocre. Entertainment would have been good but GE touchscreens are so old, they were difficult to work."

Cons: "Once In London, we were told by British Airways that was flying us to Nice that Delta had “lost” our infant electronic ticket - It took 1.5h to get new ticket reissued! We missed our connection and had to wait 3 more hours for the next flight - We were somewhat lucky as multiple flights were delayed/cancelled that day - I will avoid using Virgin Atlantic in the future as they need Delta and British operate their flights and this makes it prone to issues like that"

Pros: "I like flying Virgin whether Australia or Atlantic!"
Cons: "Just a little bit more leg room."

Pros: "The crew was the best part of my experience, super nice and accomodating"
Cons: "the wifi had subpar performance"

Pros: "The crew was excellent. Flight was quite comfortable. Nice attention to service"
Cons: "I would have appreciated another round of hot drinks."

Pros: "Even it was a 12-13hrs flight, I had been my best flight ever in a long flight. Virgin really exeeced my expectations."

Pros: "I was selected for additional screening at the gate. I have no problem with this at all. From the start I told them I am traveling with my fiancee. They tried to hold me back in a separate area after the screening and I once again told them my fiancee was waiting for me. One staff memeber walked with me half way back to get her and then disappeared. By the time I found her and came back, the staff memeber was no where to be found. Now we had lost are spot in the line and had to go to the back of the line. We spoke to 3 different staff people about what was going on and everyone said, oh the guy over there will help you. But no one did. The staff had No idea how to run a security check or handle paople. There was No working wifi! There was no tvs in the seats, only the old style in the aisle. The staff told me the plan was going to retire at the end of the month. The food was more for animals then for humans! We got updates by txt 10 mins before the staff updated the gate on our flight out from SFO. I have traveled all over the world with a lot of airlines and Never had such a poor service, but what is it to expect. It was United after all!"
Cons: "Refund of the whole flight."

Pros: "Helpful flight attendants"
Cons: "Delay at the airport due to system down where agents had to check in everyone manually"

Pros: "I was very impressed by the generosity you show concerning food och drink. the staff was kind and glad."
Cons: "I never understood how to connect the earphones to the screen so I couldn't ser any movie. But - I could have asked the staff of course ..."

Cons: "Very small leg room"

Pros: "Entertainment selection Cabin Service associates were very good WiFi service available"
Cons: "The planes are old and tired, new 787s on this route are long overdue. Thomson's premium service is an improved offering over Virgin and offers more inclusive extras such as lounge access. There is no wonder wall on the 747 only a wonder "basket" If you are flying from Gatwick, upgrading to premium isn't worth it. Go to upper class or fly with another airline. Check in was quicker for Economy passengers and it proved a challenge to work past the economy passengers during boarding to get to the premium agent."

Pros: "The speed of boarding, then the frequency of service. Cabin crew were very dedicated. All in all, a very smooth flight. Ps. my first Virgin was called Carole. ;)"
Cons: "The food left a lot to be desired, but apart from my flight on Emirates to Auckland, Airoplne food does tend to be somewhat......mmmm not sure what the word is, but room for improvement describes it."

Pros: "Food was good, crew was nice."
Cons: "Seat was broken. Button was stuck in so I couldn't keep the seat up. Also a light was stuck in the on position for the entire flight not allowing people to sleep."

Pros: "1st class, what's not to like?"

Pros: "The service, the service. My wife got a cheese and fruit platter after dinner. Crew went out of their way to make us feel special and welcomed. Excellent service."
Cons: "Nothing to complain about."

Pros: "Nothing"
Cons: "Crew had poor communication, didn't seem friendly or helpful, no food given for free and no warnings fhat this was the case. Flight was delayed at takeoff And they did not accurately tell us how long the delay was"

Pros: "Plenty of leg room Open area for self-serve snacks and non-alcoholic drinks Food was very good Super friendly attendants"

Pros: "First off,the staff is awesome. From the check in people to the flight attendants .... The entertainment was up to date and the safety video was awesome.. Great conditions for economy class.good leg room...I give them a 5 star rating ... I only wish they would do more flights to other countries overseas ..."
Cons: "I can't think of anything I didn't like"

Cons: "I couldn't rank the food or entertainment as I didn't try the food since it was for purchase only, and there was no entertainment offered."

Cons: "Why are there no plug-ins?! That was very disappointing..."

Pros: "Entertainment was okay, flight crew was nice"
Cons: "After checking in my wife and I were in separate seats. I was then unable to change my seat after check in. After calling the helpline I was informed that it is impossible to change the seat after checking in until I am at the airport. No other airline has such an obscure, in efficient rule. Virgin takes pride in being a step above their competition - I didn't see it. I have flown international on Delta, American Airlines, British Airlines, United, and others and any difference in the experience was negligible."

Pros: "Very friendly and helpful staff! Food was very good too."
Cons: "More leg room always desirable"

Cons: "The carrots were hard and the bread was cold."

Cons: "I would ask that the gate does not share in detail reason for delay in seat assignment is related to getting a family sitting together when the basic rules should apply unilaterally."

Pros: "Got to my destination without any issues"
Cons: "Seats/seating area are too small, and I'm not a big person."

Pros: "No"
Cons: "The flight was delayed almost 6 hours, the crew was rude and the “comfort +” seats had very little leg room ."

Pros: "The flight was on time, the crew was pleasant and looked like they enjoyed working in the air."
Cons: "Our second time on a 787 Dreamliner across the Atlantic as about the same as the the first. The seat pitch is very tight so when a passenger reclines into the next row the seatback nearly touches your face. The Dreamliner seats seem to be very hard and it's difficult to get comfortable."

Cons: "Flight was delayed a bit due to a couple passenger booking/misc issues. 1st class didn’t get gate bevfood service. Oven was busted so my meal wasn’t available. Entertainment console had all channels functional except — not really an issue I just really wanted to have ESPN playing in the background"

Pros: "Son got wings, so was happy."
Cons: "No entertainment."

Cons: "It was late"

Pros: "Good snack selection. Crew was personable."

Pros: "Crew was great."
Cons: "Couldn’t hear/understand the pilot"

Pros: "Flight attendant in first class was amazing."

Pros: "Jeff was our flight attendant in first class. He is an excellent flight attendant. He has an amazing attitude and his manner made us feel as if we had been friends with him for years."
Cons: "Passengers who pay retail for first class on domestic flights should get access to the Delta lounges even without the AE card. Other airlines do this, and we have come to expect it."

Pros: "The boarding was fast and very well handled."

Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires. No one helped and did not know that the flight was delayed and I had to find a place to sleep. I'm not satisfied with the experience and I have not yet arrived in Argentina because of the whole"

Cons: "It was delayed"

Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."

Pros: "There was a bit of a mixup in boarding the plane but otherwise the flight was good. There was no entertainment system on this short flight. The flight attendants were very pleasant & efficient. They only served snacks on this short flight but were very good at ensuring everyone had at least one or more beverages. The premium seats were very comfortable ."

Pros: "Short flight"
Cons: "Flight attendant was not willing to go above and beyond as he stated he would. My husband asked for a coke and the flight attendant told him he could only get water."

Pros: "It was a smooth boarding, flight and exit out of the plane."

Pros: "On time departure/arrival despite weather in Atlanta. Always a fan of free messaging and choice of snacks."
Cons: "Delta needs to invest in their gate area at ORD. Understand it’s not a hub but it’s a key business/leisure destination. The MD-80s are ok for a short hop but over 1 hour unless you’re in Comfort+, it’s tight."

Pros: "Snacks, cleanliness and crew"
Cons: "N/A"

Pros: "Nothing"
Cons: "They take them forever to find me another fly ,make miss my other fly, my work my time and my sleep"

Cons: "Entertainment app from Go Go didn’t Work."

Pros: "It was a normal flight as well expected."

Pros: "I was given a complimentary upgrade."

Pros: "The crew and pilot were absolutely amazing."
Cons: "This is my 3rd delta flight in a row that has been delayed. I understand these things happen, just extremely frustrating."

Pros: "Great service, nice agent friendly"

Pros: "Very friendly and professional gate agent and flight attendant"

Cons: "I was unable to fly at all due to a spelling error on my ticket. The airline refused to alter the ticket. Worst experience of my life, ruined my Christmas"

Pros: "Very nice flight and attentive staff. Enjoyed the view of NYC as we flew up the East River, then looped over Nassau County to approach LGA."
Cons: "The male flight attendant who handed out the complimentary drinks and snacks acted a bit strangely. I was very thirsty, and I asked him if I could keep the rest of the can of soda. He neither said yes nor no, but rather completely ignored what I said and just poured my drink and moved on. I was a mildly annoyed, but figured maybe it was policy and he was shy and didn't want to debate the matter. When he took care of the older couple behind us, however, things got really strange. He asked them whether they wanted pretzels or peanuts, but they misheard him and asked for a ginger ale. I happened to know that he did have ginger ale, since my wife had just gotten one, but rather than just pouring the old folks a drink, he repeated himself. "Peanuts or pretzels?" They misheard again and asked him whether he had a diet ginger ale. Again, rather than just pour them the drink, he repeated himself. "Peanuts or pretzels?" This went round and round a few more times -- like a poorly designed computer UI that refuses to accept anything except the correct input -- before the old couple finally figured out the disconnect and picked their snacks before their drinks. Very weird."

Cons: "Layover"

Pros: "Short flight"
Cons: "Too cold Not friendly boarding agent"

Cons: "Had a death in the family and no one would help me get back home"

Pros: "Seats were comfortable. Snacks!!! Nice flight crew."
Cons: "I liked everything."

Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."

Cons: "Plane was sat broken at gate and needed part to be flown in. 150 minutes delayed. Not acceptable."

Pros: "I missed my flight for the first time and I was having a complete meltdown at the check in desk until the sweetest agent said "oh no worries sweetheart, let's find you another flight back home"... It seems so simple but with the morning I had, this simple act had me in tears! The kindness and patience she showed me was amazing and definitely the reason I will always fly Delta to any and every destination they are able to take me! <3"

Pros: "No fee to get on an earlier flught"
Cons: "When I tried to rebook online this flight was not an option"

Cons: "I am a 5'3" 125# woman who, unfortunately, had a middle seat assignment. The passenger to my right, on the aisle, weighed approximately 375# and took up 1/3 of my seat. The arm was not able to go down comfortably, and when it did it was not usable . The passenger on my left, window seat, was probably 6'7" and had to sit with a man spread in order to fit. I could not move and was extremely uncomfortable. The plane was overbooked so I was unable to move. Therefore, worst flight ever. Plus, I paid for a full seat and was only able to occupy half of it."

Pros: "The in-flight service was good."

Pros: "Nothing"
Cons: "Poor hospitality by alaska airline staff, especially by MrPavel at gate H4, 01nov2016, prior boarding around 0730am"

Cons: "This was my first time with Turkish airline , the airbus from Chicago to İstanbul was quite old and seats were not comfortable while the plan form İstanbul to Islamabad was perfect . Thank you Turkish airline"

Cons: "No coffee no tea. Disgusting."

Cons: "Foddd no gud"

Cons: "Change the crew they were rude"

Pros: "Some of the crew were amazing and some were grouchy and not very helpful"

Pros: "The boarding, comfort and crew were excellent. Everything is very organized and professional."
Cons: "I had a 12 hour layover in Istanbul. The hotel was great and I appreciated the good food and rest. However, it took nearly an hour each way to the hotel. I think it would be great if Istanbul airways cooperated with the Yotel so transit passengers could stay in the airport. They helped me to get a visa and they say it will be reimbursed, but all of those things took time when I was so exhausted after a long flight. Overall, it was wonderful to have that opportunity to rest and shower on a long wait, but it would be even better if it was closer and it was clear ahead of time that a visa would be needed."

Pros: "The crew was great and service and meals where wonderful"

Pros: "The first trip from Chicago to Istanbul they given us the first chair with bed for baby But the next trip they not"

Cons: "being treated like a drug dealer at the boarding gate #312 and having passport / boarding pass checked several times"

Pros: "Everything"

Pros: "The flight was very accommodating. Everything from eye shades, tooth brush and slippers were provided. I took the red eye and slept the whole way."

Cons: "Was hot before taking off then had cold air blowing directly on my neck. For most of the trip it was comfortable."

Pros: "The service, food, and in flight entertainment were great. The leg room in coach was on par with other major carriers that I have flown transatlantic. The layover in Istanbul was pleasant (go to Staarbucks for free wifi). And I saved $500 over the price of other flights. I'd definitely take Turkish Airlines again, and maybe even arrange for a longer layover to be able to see Istanbul."

Pros: "First of all, the food is fantastic is you are not a meat and potatos (or big mac) kind of person. My original flight left late due to a hold up in security in Chicago.

Pros: "Nothing whatsoever."
Cons: "Worst customer expireince ever. I was making a short trip to visit my very sick mother. Turkish Airline changed my connection time without notifying me such that I had 5 min left for my cooection in stambul. They gave me no other option and blamed this on Kayak and kayak blamed it on the Airline leaving me with no options. I had to stay in Birlin at my own expense. Complaint filed with Turkish airline resulted in nothing. I made several calls for update and only repose I got was we will send an email to the complaint dept. and you will here in 24 hours. This has been going on for over 5 days with no contect, update or resolution. Once back in the US, I plane to file a formal complaint with FAA and more. DO NOT take this airline. They are worst airline I have ever used and will never use it again."

The plane also had Florescent lighting that changed colors every 20 seconds for the first 2 hours of the flight, my wife got nautious. At 11:30pm they served supper, which the food was good but this was supposed to be a red-eye so we were expecting some rest. The lights finally went out at 1200 midnight. They turned them back on at 6:00am for breakfast. I will never under any circumstance fly Turkish Airlines again."

I just filed a claim and got rude service saying I should have filed the claim at the airport baggage area but there was not anybody there to do the claim then he agent upstairs said they just spoke to them and they are there and I should have done it there. This was so rude and there is no way to get back into customs area. If we paid 200 for bags I expect them to arrive on time. I’m asking for a refund of the baggage fees."

Cons: "Bit cramped for space"

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: "787 is a great airplane. The 3-3-3 seat configuration leaves enough seat width to be just comfortable in coach."

Pros: "Flight was delayed for three hours and was a very stressful flight"

Cons: "Two hours delay in the start."

Pros: "I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly"
Cons: "Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in flight!"

Pros: "Everything. Staff incredible."

Pros: "Food and staff were great"
Cons: "Entertainment system old and not as many options as other KLM flight. No power on aircraft for charging"

Pros: "Excellent service, excellent food."

Pros: "Good flight, we got a nice snack despite it being a short flight, the staff was great."

Pros: "Crew was excellent"
Cons: "Economy was very tight! Seats were uncomfortable"

Cons: "I missed my flight because of MU"

Pros: "I liked the leg room, I liked the customer service of the crew, smooth flight."
Cons: "Both ways up and down I struggled with over-head luggage space. We were allowed a cabin bag and a small hand-bag in the flight but as we were among the last half of the passengers to board the flight we couldn't find anywhere to keep our luggage and the crew had to take them away from us to store them somewhere at the back far away from our seats. As a result we had to wait until all the passengers got off the plane to get back our luggage and we were the last two passengers to get off. Unpleasant!"

Cons: "Our flight from Nairobi to Lusaka was cancelled for some reason and we did not find out until we happened to log into the website to double check our itinerary. They automatically rescheduled the flight only giving us 25 minutes to reach our next flight...impossible. so, after calling, we were re-booked again and forced into a 13 hour layover in Amsterdam. Our original flight plan had 4 hours. so, because we are a family of 7 with a baby, we had to buy a hotel room to rest, costing us a lot of extra money we had not planned to spend. We contacted KLM for help with the cost but were rejected. We also lost 5 bags somewhere between Chicago and Lusaka, but after 2 days, we received them."

Pros: "Delays and no proper customer service."
