Airline reviews

Cons: "Flight delayed, sat on plane on ground for 4 hours then missed connecting flight."

Pros: "The crew was nice, the food was really good, the plane was clean, and they used reusable silverware and plates to avoid waste."

Cons: "It’s frustrating to not have the ability to select seats before arriving at check in counter when there’s really not much to choose from."

Pros: "The entertainment was good"
Cons: "The food on the 2nd flight was bad"

Cons: "70’ late on a 45’ flight"

Pros: "Crew was amazing"
Cons: "Entertainment and dinner food"

Pros: "The food was the best I've had on any airline in recent times. On the first flight it was a croissant and a swiss chocolate, on the second flight it was a hot danish pastry."
Cons: "The first flight was late so I was worried I'd miss my connection (however connection was delayed too so I made it). Also, I was asked to check in my bag because "the aircraft was full" however when I got on the plane I noticed it was half-empty and there would have been ample overhead room."

Pros: "The flight was smooth and on time. The flight crew did everything alright."
Cons: "Connecting flights. All lies, no cooperation. Not a small airport as it takes nearly half an hour to get to Gate E. Too few characters allowed to explain all we went thru."

Pros: "Short flight, no entertainment. They still offer free snacks on short flights, a plus, but it was an almost frozen cheese sandwich. A Little bag of pretzels would be better. The crew was very friendly."
Cons: "Boarding is confusing. Bad lines, unorganized, and people pushing. They should probably come up with a better system."

Cons: "Too hot. Too late. Staff could have been more accommodating. Online checkin was impossible."

Pros: "Customer service excellent even though I was in the economic class they made me feel first class!"

Pros: "Efficient, excellent staff and service, beautiful plane"
Cons: "There was a nearly impossible connection time in Zurich."

Pros: "Nothing"
Cons: "Delayed, bad entertainment system, lost our luggage"

Pros: "Nothing about it"
Cons: "They didn't even take us!"

Cons: "2.5 hour delay, missed connection, arrived more than 5 hours after originally planned. Entertainment system did not function. Crew did not collect garbage/unused items prior to landing and I was holding garbage in my hands during landing (and some spilled on my lap)."

Cons: "carry-on baggage procedure not clear. deal with this issue upfront, not at end when cost is 3x more so Swiss can make more money this way."

Pros: "Our flight on Swiss was excellent. On time, courteous crew, and loved the morning Croisant and the chocolate. As my wife and I are both retired flight attendants with TWA and American, we tend to notice customer service at all levels of an airline’s operation. Both our flight out of LHR to GVA and our return were smooth as can be. Nice job, Swiss!"

Pros: "Though our flight got delayed, we arrived almost on time."
Cons: "Because the flight was delayed, boarding seemed a bit chaotic. Everybody tried to board at the same time. The seat had technical issues - it would either recline or be upright. The crew had to spend quite a bit of time trying to figure out how to return from a flat bed to the upright position. Entertainment was re-booted 3-4 times during the flight to get it to work consistently."

Cons: "Excelent"

Pros: "Nice staff, very friendly"
Cons: "Paying for WiFi, could use more comfortable seating"

Pros: "staff was very nice"

Pros: "Friendly and high quality service"

Pros: "Crew was attentive and friendly"
Cons: "Very disorganized boarding."

Pros: "Swiss took care of your mistake, booked on subsequent flight."
Cons: "No idea a you never actually delivered a ticket. Flight over sold, Swiss had no record of the booking. KAYAK screwed up."

Pros: "I am very satisfied and I will recommended it to my friendships"

Pros: "-"
Cons: "- late in arrival - 2h late in departure - lost my luggage"

Pros: "Smooth flight"
Cons: "Crew just ok."

Pros: "Or print out a boarding pass. Much unlike our experience with Lufthansa flying from Boston through Frankfurt to Geneva."
Cons: "See sbove"

Pros: "Easy, on-time and courteous"

Pros: "Loved the smoked salmon!!"
Cons: "No wifi or tv"

Pros: "Crew and people were fabulous!"
Cons: "LONG lines at check in. Almost missed flight even being there 90 mins early."

Pros: "Crew was great."
Cons: "My wife is strictly Hindu vegetarian. We had entered her food choice at Swiss web site months before. She didn't get the food while going to Zurich and coming back to Boston. She remained hungry both ways. Although we were in business class while coming."

Pros: "Boarding without frills. On-time departure. Overall good food. Great cabin crew; they took care of a toddler with a fever and her mother."
Cons: "Nothing"

Cons: "1 hr 50'' delay"

Cons: "Small spaces between seats"

Pros: "They put us in a nice hotel"
Cons: "Flight was delayed for more than 1 hour and it was overbooked. So they put us on a united flight for today. This flight is also overbooked."

Pros: "The staff was helpful and professional and kind. The equipment was new and clean. The flight was on-time and uneventful. I would fly this airline again any day of the week."
Cons: "The entertainment screen was difficult to see when the person in front of me reclined because the screen was not perpendicular to my line of vision. I survived based on the other qualities of the flight."

Pros: "Friendly attendants responded to every need. Chicken with rice meal was very good."
Cons: "The sound system for movies was distorted."

Pros: "I don't think I'd ever experienced such a friendly and empathetic crew."
Cons: "Security was a disaster in Amsterdam. Lines were long and they were checking everything - e.g. My bag had to be screened 2x because of my Kindle, which never happens. But the crew was Extremely accommodating and helpful."

Cons: "flight was delayed half and hour and i missed my connecting w"

Pros: "All good"

Cons: "priority luggage arrived in SFO about 30 mins after regular luggage"

Cons: "I was taken away from boarding for a random check that took a long time due to not enough staff Entertainment system was broken for about 50 people, even after a reset. Terrible for an overseas flight. Food was very poor, staff lied about resetting the entertainment system. The plane took off 1 hour late and was not allowed to taxi to taxi to the gate for 1 hour, making us extremely late."

Pros: "Decent food (great chocolate), polite attendants and updated aircraft"
Cons: "Contrary to most experiences in Switzerland, the Swiss Air boarding process is a damn mess! Most airlines board by rows or boarding groups, but Swiss Air does none of that. As soon as first class is boarded, they open boarding to all seats, so it's like cattle boarding a train. With Swiss Air, don't wait to get in line - do it early to ensure you get carry-on storage near your seat."

Pros: "I like that this plane had more leg room then other airlines."

Pros: "Ok food and ok entertainment"
Cons: "Plane was very hot and there were no air conditioner valves so we had to sit in a hot plane for thirty minutes. Seats didn't recline at all so sleep was out of the question. Just a very miserable flight overall."

Pros: "Excellent flight attendants."
Cons: "The boarding process for the economy class seems a little chaotic since there is no distinctions by zone or seat row. The result is a surge of people right when they announce boarding for that cabin."

Pros: "Cornella was my flight attendant and she was amazing! Such a sweet woman. Someone give that beautiful lady a raise, extra week of vacation and a high five for me. Food was great. Drinks were plentiful. Seat was comfortable and I felt the pilots did a great job of finding the smoothest flight path."
Cons: "Entertainment selection left something to be desired. When comparing to Virgin it is tough to be anything but disappointed."

Pros: "The seats were actually more comfortable on this short leg than on the much longer flight back to Boston. And the Swiss chocolate was good."
Cons: "Having to pay for a second checked bag. And the refreshment (I think it was supposed to be ice cream) was awful. Also, I think it was the young pilots virgin flight. The jerky take off and bouncy initial flight was capped off with an approach to the runway for landing that was very scary, much too fast and wobbly. Thankfully the plane was pulled back up into the air, just before touch down, circled for ten minutes, and retried the landing. This time perfectly smooth and successful."

Pros: "Everything was better than expected."
Cons: "Nothing"

Cons: "This flight was probably great but I was not on it"

Pros: "Most comfortable seats of the three flights. Crew friendly and attentive. Acted like they enjoyed their work."
Cons: "Luggage still in Atlanta with Delta."

Pros: "quick and efficient"
Cons: "I know it's not the airline's fault, but we were delayed for weather. Also seats do no recline and there is no entertainment."

Pros: "Crew was very pleasant"
Cons: "Old airplane. Everything was worn out and stained. Entertainment system is ancient. Economy seats are so small you can barely get in and out."

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "Since I wasn't allowed on the flight because another leg caused us to arrive with only an hour to board, I can't tell you anything that was enjoyable."
Cons: "The KLM representative was COMPLETELY unhelpful. She basically told us we were screwed and to go away. We spent hours on the phone at great cost to us (international pay phone charges) to be bounced for one rep to another. We were finally told we could get in a plane home Sunday, please to be transferred, starting the process over from the beginning. It was TERRIBLE, beginning to end!"

Pros: "Going back home to the US"
Cons: "I had 15 hours layover in Amsterdam so I got me a hotel.one hour after I got to the hotel I got a notification from Kayak app asking me to go get my bag from Schiphol. My bag was supposed to be directly shipped to PDX. I had to leave my hotel back to the airport and spend 2 hours trying to find it only to be told that it was going to PDX. I lost my $170 hotel room, over $70 for taxis and ended up spending the night on the floor at Schipol. I do not think I'll ever use Kayak again. The travel guarantee is a joke too."

Pros: "Pilot welcome to the plan was very nice seats was comfortable food was good"
Cons: "Crew attaitude is not really pleasant with passengers"

Cons: ". The flight was overbooked and I had to wait for last minute to find out weather I will be on board of the flight .My bags were left behind in Amsterdam which were delivered later than they were supposed to."

Pros: "Good flight overall"
Cons: "Although I have priority status -The ground crew in Amsterdam gave me hard time with 7 extra Pounds, and I was trying to take it out of the suitcase to no avail. Eventually the agent I was checking in with got busy, I went to a new agent, and with a flick of a keyboard he approved the extra rate based on my status, without even have my to request it."

Cons: "No dairy free options!"

Pros: "I love the overwhelming positivity exuded by the stallions in business class. Sometimes good things happen to mediocre coffee, others not so lucky!"
Cons: "The guy next to me looked like Joel Osteen and his daughter was actually Cardi B. I could feel the existential dread coming from their tray tables. Also, Lemon and Caramel cheesecake? What an awful flavor combination."

Pros: "seat was fine."
Cons: "A/C was blowing right on our heads. Asked to have the A/C turned down. They said sure. The nothing. Asked again? Nothing. 3rd time, my neighbor and the people in the seat ahead told them that we were ll cold. Nothing! I was sneezing by the time we landed."

Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."

Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."

Pros: "Friendly staff, good service and on time departure/arrival. Was also quite pleased with the food options available during such a long flight."

Pros: "On the first leg I liked the entertainment options. There were plenty of current content to watch and the screen was good enough. I still resorted to my iPad after a while but it was more because I wanted to watch something specifically rather than I had to. The food was decent but as usual the good stuff runs out before you get your turn. Order special food next time."
Cons: "I don’t like any airlines boarding process in general. They always seem inefficient and slow. I didn’t like the free headphones they passed out. They’re so awful that they really ruin whatever you’re trying to watch."

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

Pros: "About 10-15 yrs ago I stopped transatlantic flights on Delta. It was a scruffy airline with uninterested cabin crew & not to talk of food etc. What a change! Neat clean A330, friendly crew & food + beverages to brag (you pay outrageous prices on 'leaner-meaner' airlines if at all available). Loved the whole experience. Flying is not only getting from A to B & Delta has realized it. Looking forward to my next Delta flight!"
Cons: "NOTHING"

Pros: "Great in every way"

Pros: "A good basic no frills flight"
Cons: "Luggage missed the flight and was delivered later that say. It is the same as happened the last time we took this flight."

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Cons: "The most horrible experience. Pathetic to say the least. No water in the flight lavotries. Such a pathetic service from so called top airline."

Pros: "The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!"

Pros: "Flight crew was pleasant and attentive. Seats were comfortable for economy as well. Food and beverage service was excellent along with entertainment options."

Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"

Pros: "Entertainment system was good, great crew, great food, great service"

Cons: "Smooth and easy"

Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Nice service for short flight"
Cons: "Lost luggage for 2 days."

Cons: "This flight was on a Transavia codeshare with Delta and a real downer after coming from a Delta One business class segment. An uncontrolled mass boarding, crammed in seating, no amenities and charges for a drink of water made this a pretty crappy flight. The crew was nice though."

Pros: "Great stewardesses, good food"

Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."

Pros: "Good staff, crew, amenities in the airport, courteous and helpful."
Cons: "Schiphol has an excellent system in place -- you get through all the checkpoints to the gaits in less than 15 minutes. Then at the gait, at least at Delta/KLM they re-check all the documents twice, and that part takes 40 minutes -- so be prepared to come early to take that into account."

Pros: "Left on time, arrived early. Great cabin service, attentive and polite. Comfort Plus seats are worth the extra few bucks."
Cons: "Nothing. Low rating for entertainment only because there really wasn't any, but I wouldn't have used it anyway, so no big deal."

Pros: "Good service once I finally got on a plane."
Cons: "The alternative routing after my missed connection was not good and would have resulted in a very long travel day on a comparatively ill-equipped aircraft. So I stayed in Amsterdam on my own dime to take the same direct flight one day later."

Pros: "All went as planned and expected. No thrill- like taking a Greyhound bus in the old days...gets you where you are going but without much pizzazz New seats and quite clean, but the new seats were very hard and uncomfortable after an hour."
Cons: "Somewhat claustrophobic and always wish the drop down tray table behind could be disconnected from my seat. When the passenger behind uses the tray as a set of bongo drums to keep beat with his headphones it is a pretty miserable trip."

Pros: "Food was good"
Cons: "No bags in Atlanta and no one to help. In Savannah baggage person not nice. Started the conversation telling me Delta is not responsible for delivering our baggage to our home."

Cons: "I'm not sure how you lose a bag on a direct flight from Atlanta to Denver, but Delta found a way to do it. They didn't even put my bag on the plane and had to send it with the next one coming. To their credit, they did drive it out to my house when it got here."

Pros: "The only airline that I'm aware of that still offers: • free snacks • free checked bags • free meal and drinks on international flights"

Pros: "Delta is focused on customer service, especially in the business class. Great airline. Love the crew attitude."

Pros: "Good flight and good meals"

Pros: "Nothing"
Cons: "everything else"

Pros: "The food and service was good. the Washrooms were good."
Cons: "The seats were too small, the built-in monitor in the seatback was kinda junky"

Pros: "Appreciate having movies available through wifi however didn't realize this until only an hour left in flight."

Pros: "Excellent service"
Cons: "Plane was a bit old"

Cons: "Luggage was not received. Now being told it will take up to 5 days! Unacceptable performance"

Pros: "They were smiling and very welcoming"

Pros: "It didn't crash."
Cons: "Food no screaming babies . Comfy seats and armrests,"

Pros: "Crews was excellent, always refilling water which I can appreciate so much. Keep it up! Loved the United pilot at John Wayne who came out just to say hi, let us know we were in good hands."
Cons: "Had to wait in tarmac forever from Frankfurt to Florence"

Pros: "Flight itself was good. Crew was nice"
Cons: "Flight was late. Airport experience in Frankfurt horrible. It looked like all was intended to increase the delay. They made me miss my train connection"

Cons: "My luggage did not make it with me."

Pros: "The crew was professional and polite"

Pros: "Nice plane, about the best in-seat entertainment options I've ever encountered."

Pros: "One flight attendant in particular was outstanding, Eva. Because of her, I would definitely consider Lufthansa for our next trip to Europe!! She mot definitely went above and beyond in her service and professionalism."

Pros: "Best part was how Lufthansa took care of travellers whose connection time was short. They had ground crew waiting and who escorted us through customs, and then drove us to the gate. This is how passengers should be treated. ~ Excellent movie selection ~ Great flight attendants"

Pros: "Some how i ended up in the "small child zone", The crew was very kind and moved me to another aisle seal towards the front of the plane. Crew would come by with liquids quit often, The food was very good quality. huge selection of entertainment options."
Cons: "A very long wait for luggage, That may have been the fault of the airport."

Pros: "Lovely crew"
Cons: "Airport is too hot"

Pros: "Excellent service, food and entertainment"

Pros: "Was not allowed on flight"
Cons: "When I missed the connection from the first leg of my flight and purchased the ticket from that leg to finish my itinerary, Lufthansa cancelled ALL of my return tickets. Both Lufthansa and my travel agency pointed the finger at the other and I had to purchase another $1000 ticket to get home. There was no cancellation emails or any notification. I didn’t know my tixkets were cancelled until I was trying to check in. Worst experience ever!!"

Cons: "Missed so there was none Spent night in Minic"

Pros: "Staff were amazingly helpful n friendly. Food was yummy."

Pros: "All airplane was on time"

Pros: "Great service and flight crew"

Cons: "Nothing"

Pros: "Great service both before boarding the plane and while in flight. The check in line was out of control, but lufthansa staff members ensured that I could still make my flight."

Pros: "Air dolomiti - great service, prosecco in a real glass and with small sandwich provided."

Pros: "We were well taken care off for a short flught"
Cons: "Nothing really"

Pros: "Crew was more understanding. Placed us to row 18...emergency exit."
Cons: "Checked online from row 21 to 6. Got a new ticket whilst boarding to 25: last row. Explanation...otherwise the plane was not able to go in the air...absolute bullshit. With my weight and of my fellow members better to let us in the front.. Row 6 was given to a miles & more client..."

Pros: "Plane not full so we hat an extra Seat"

Pros: "the woman who helped me at the boarding gate was great! Lounge was really nice!"

Pros: "The energetic crew who served with a smile"
Cons: "The tea was not strong and was served lukewarm and movies not up to standard.how about new blankets...and food only a choice between 2...chicken or pasta..why not beef or mutton?"

Cons: "Same as Abu e"

Pros: "Nothing no communication for delayed flight lost luggage. Just lines everywhere to fill out forms with only 2 employees worst experience ever"
Cons: "No communication. Flight delayed no answers. Just long line to be put on a waiting list"

Cons: "First flight mechanical issue so couldn't make it to any of my connecting flights and they had to reroute me, however they couldn't get me to Torino so they got me to Milan and I had to take a two hour bus and then the metro to get where I needed to be. And it took them over an hour to reroute my flight!"

Cons: "Flight delayed 1.5hrs after landing in Denver."

Pros: "Crew was beyond standard. Very nice and friendly and always accommodating."
Cons: "They ran out of vegetarian meals."

Pros: "The food was nice and the stewardess were professional."
Cons: "My ticket didn't specifically say I'm not allowed to have check-in luggage, so I needed to pay extra for that. I also got too little transfer time and barely made it because my flight arrived late. Then, my luggage got lost during the transfer, so I had to wait for 5 hours, which made my plans a mess. Overall not satisfied with my flight"

Pros: "Nonstop flight."
Cons: "The seats are the most uncomfortable I've ever sat in. The food from Frankfurt to Denver was subpar. The first 2 hours were very bumpy and unusual for that part of an Europe to USA crossing. The spacing of the middle seats with the support struts having to straddle for 13 hours is too much. I could go on, but you really need to rethink the design and customer service on your long haul flights."

Pros: "Our flight out of Amsterdam was roughly 30 minutes late. Since we were connecting to an International flight to return to the US there was no possibility we would be able to get to the International terminal through security and board our flight in the time available. So, Lufthansa staff met the connecting passengers as we disembarked, shuttled us via bus to the International terminal and ensured we made our connection. Finally, for airline food it was quite good (Vegan)."

Pros: "Hope to make today's flight home! Time will tell."

Pros: "You'r aamazing, great deals! Thank you!"

Pros: "We arrived 15 minutes early, which is always great!"
Cons: "They ran out of the chicken for dinner and only had manicotti left, which was horrible! No apologies for running out of 1 of the 2 options. The audio was horrible. In order to watch the movies, I had to hold the cord in 2 places in the exact right manner, or it would cut out and there would only be silence. Not fun trying to maintain that position for 9 hours."

Pros: "Great crew, very attentive. Excellent food and beverages! You don't get off of Lufthansa flight hungry! Good choice of entertainment. Lufthansa really knows how to take care of its customers on long-haul flights!"
Cons: "Online check-in is very difficult. told me that my request couldn't be completed, then when I got to the airport, they said "Oh, I see that you have already checked-in!""

Pros: "Staff attentive. Came by very frequently."

Pros: "We got there"
Cons: "Seat back entertainment? What a joke! It was like watching a movie on a Motorola Razr (or my old Ericsson flip phone). Surly old battle axe sky waitresses. 90s vintage plane interiors. Need I go on?"

Pros: "We cheked in on line At Amsterdam airport at the drop of lugage was a nightmare Line out the door wich made us almost missing the plane"
Cons: "We cheked in on line for our flight Amsterdam Boston Ariiving at 5.05 AM for our first flight to Frankfurt at the lugage drop of desk There was a line out the door wich made us almost mis the plane At the gate they had problems with my carier on The same carier on is traveling with me for more than 15 years and never denied plane acces Result all my creditcards/money and important documents where not longer withs us So we could not buy a drink or food at two airports There was plenty of space in the overhead compartments above our seats That part of our experience was very bad Tnx"

Pros: "The flight was relatively empty, so I got to stretch out across three middle seats and sleep for the entire duration of the flight. The crew did a wonderful job of serving the food and clearing away very quickly. They were very friendly overall."
Cons: "The entertainment system wasn't the best I've seen -- but I barely had a chance to use it, so I'm not complaining."

Cons: "Bad food, surly crew, old plane nor properly cleaned, ancient entertainments system, cramped seating"

Pros: "Liked the check-in service - no long lines, friendly attendants."
Cons: "1. I was not aware or told that in-flight entertainment via Ipad required the united app. So I could not use that. I would appreciate better communication. 2. At one time, a crew member stuck his nose in the coffee pot - I think to smell which pot was coffee versus tea. But heck, who wants coffee after that? 3. The final lunch served was a sandwich that required heating of the sandwich. Served cold it was dry. By the way, the wrapper said the sandwich is oven ready! Good gracious. Follow the directions. 4. The attendant who served dinner came across as rushed. Like he was on a schedule or something. Are you guys timing the attendants? I personally felt he was rushed and cared more about dumping the tray in my lap than about looking me in the face and making human contact. 5. I fly to Amsterdam a lot and prefer the direct flights, ie KLM or United. So far KLM is winning me over in terms of service. I do think though that United can make easy improvements and provide better service. Remember, you are transporting people, not packages. Good luck."

Pros: "crew polite."
Cons: "Freezing cold !for 9 out of 11 hrs. On the outbound flt HOU-AMS snacks were complimentary...On return flt AMS- HOU they charged us. Not sure what the difference would be coming or going ?"

Cons: "A worker at the check-in stand in Schiphol airport was very rude. We didn't get Lufthansa even tho I booked through them. And instead we got America airlines."

Pros: "The wide selection of movies, tv shows, etc that were available to us."

Cons: "I booked Lufthansa. I should have been on a Lufthansa flight not a United flight which is a inferior airline."

Pros: "Being assigned seat only ten minutes before take off is not ideal"

Pros: "Jumbo plane was comfortable."
Cons: "The long lines to renter back to the state at imigration"

Pros: "Excellent very good"
Cons: "Everting so good ex"

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."

Cons: "Our flight was canceled from Amsterdam to Bordeaux and did not receive any direction and had to find alternate flights for ourselves with the personal expense of using our own cell phones. Then our luggage lost for 3 days. Not happy! We ended up flying from Toronto to Paris then to Bordeaux. Lost my upgrade money for seats. Now have to deal with KLM for refund!"

Pros: "Catering is ok"
Cons: "Seats comfort really old school"

Pros: "Loved this 747! Crew was professional and food was very good."
Cons: "We had a long wait (25 minutes) at the gate because we were early."

Cons: "The fact that there are different airline carriers for one flight is hard. In my second flight they made me check a bag which was considered a carry on during my first flight"

Pros: "Fortunately, the plane was not full, so people could spread out a bit to create extra room. The food was really good! (surprisingly)."
Cons: "KLM's new configuration for this type of plane made the seats even narrower than before. While leg room was reasonable, the 3 abreast seating meant a lot of discomfort, especially in the row right in front of the restroom."

Pros: "Speed, crew, and reliablity."
Cons: "Food wasn't good, no entertainment or accessory plug ins, and seats were worn out! Not comfortable at all. Great leg room though."

Pros: "Same as above"

Pros: "Night flight so no entertainment allowed sleeping"
Cons: "Kosher food could be improved"

Pros: "Same as above"

Pros: "Friendliest economy class service I've ever encountered."

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

Pros: "leg room economy compared to KLM"
Cons: "full flight, no upgrade possible"

Pros: "Enough space good wine and on time"
Cons: "Nothing"

Pros: "Unexpected surprise--even on a 1 hour flight at noon, they gave us a sandwich!"

Cons: "With skyteam elite status cannot select free upgrade from economy to premium economy unless it is 30hrs before boarding for this code share which is actually a KLM flight"

Pros: "Special treat for King's Day Friendly crew"
Cons: "15 min late boarding 30 min delay leaving the gate Very little leg room"

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."

Cons: "I slept didn't have snack offered and no entertainment"

Pros: "No entertainment or food needed on a half hour flight. Otherwise excellent."
Cons: "Nothing​"

Pros: "Except for my negative comment, a good flight."
Cons: "I paid extra for a window seat, but due to the poor alignment of the seats with the actual windows, I actually sat next to a wall! Nol much to see out of a wall. If KLM are going to charge extra for a window seat, then they should make sure there is a window there! If the seat had actually had a window it would have been an excellent flight."

Cons: "Very slow service. I wanted to by several goods from duty free. But crew served only first 20 rows of aircraft."

Cons: "Fewer entertainment options than the delta flight. I got excited with that first flight."

Pros: "Service of the staff was great"
Cons: "Turbulence, with all our technology we still cannot avoid this?"

Cons: "Since we had two extra bags (paid for in Chicago), they demanded to see my receipt before we could board in Amsterdam to Nairobi. We had trouble locating the receipt and we were not given an explanation as to why we needed it again. We were traveling with 5 kids including an infant and we were not allowed to board until we found the receipt. I thought surely they would have record that I had paid, but I guess not. We were the last to board and all very stressed out. The staff seemed not to care the least in our troubles."

Pros: "In general, it was ok"
Cons: "Yet again it was flight delay from KLM side."

Pros: "Great food and movies."
Cons: "Might have lost my bag. I was told not to claim my bag and that it would meet me at my final destination. That did not happen. I even paid extra because of the over weight. When they charge you 100 extra euro you expect your bag to make it to its final destination."

Pros: "Food was relatively good"
Cons: "We had ourtrip from San Francisco to Amsterdam which is one of the longest flights ever, andthe entertainment system wasnt working, we kept on telling them several times but nothing happened and at the end they wereeven avoiding us. By the end of the trip when we were approaching Ams, a hostess came and she gave us a $25 dollar discountvoucher to be used in our next trip, this is totally not acceptable!"

Pros: "During my first flight from East Midlands England to Amsterdam I lost my baggage by another airlines and the KLM crew was very dedicated and supportive until they found it and check in for me... Many thanks and I wouldn't forget it."

Pros: "On-time Quick boarding Friendly staff"
Cons: "Only pre-security lounge (Air France) that is open till 19:00."

Pros: "Staff was excellent. Entertainment options pretty good."
Cons: "Seems very dated. Business Class felt cramped and not very luxurious."

Cons: "KLM sent us to Kiev thru Stambul (Turkey). We have spent 8 hours more on flights."

Pros: "New plane, new seats, new entertainment system. All very goo to great. The dinner was above average in terms of taste but the breakfast was pretty ordinary."
Cons: "Breakfast food wasn't very good."

Pros: "Friendly crew. Good snacks. Timely updates about delays.cr"
Cons: "Crew forgot to serve several rows of seats including ours. Came around when reminded, but then said didn't have enough hands to carry trash away and told us to store cups, etc in back seat pocket when landing."

Pros: "The cabin crew was very friendly and helped me to move from a center seat to an aisle seat. They were good natured throughout the flight, especially one gentleman. The main meal was also surprisingly tasty."
Cons: "The cabin crew was very friendly and helped me to move from a center seat to an aisle seat. They were good natured throughout the flight, especially one gentleman. The main meal was also surprisingly tasty."

Pros: "The delightful crew members on KLM flights always make the experience the best. From the crew at check desks, to those greeting you as you board and throughout the flight, they are the reason I continue to fly with them. I love how they have bassinets for those traveling with babies. the adventure packs for children and the never ending smiles and treats for the rest of us."
Cons: "This time I was turned away as a Sky Priority Member, and told there are too many categories at boarding and told my Silver Status (after this flight was bumped to Gold). Not sure what has changed in the last 2 weeks."

Pros: "Very good flight.I recommend it to everyone."

Cons: "Luggage lost and not found. Contact to executing airline KLM very difficult, because the case-nr. on the "lost-luggage-form" was unreadable. but without this number, you can do nothing, because it almost impossible to get someone on the phone at KLM. Mostly you talk to computers. Obviously the phone is oldfashioned and you need twitter and facebook. Poor service, KLM So you can have a pleasant flight, but if you need service, you are lost."

Pros: "Nothing really"
Cons: "The Amsterdam airport is super disorganized, with rude employees great at making excuses for their incompetence. The boarding crew really struggled to organized the boarding and wouldn't really care about people's status. We had to take a bus to the airplane, and even though both plane's entrances were open, they sent everybody to the front entrance. The comfort of the plane was horrendous, with seats over 20 years old and their business class was the same as the coach, but with no one sitting in the middle (can you get any lower than this?) The flight attendant woke me up to shove a food tray that I didn't want. We had to wait over 45 minutes after the plane landing to start seeing some luggage show up on the conveyor bell. The overall flight experience make southwest look like a luxury airline. This was my first and last time flying on KLM."

Pros: "Great dinner, and unlimited ice cream! Crew are cheerful and helpful as always."
Cons: "After status flyers boarded first, general boarding call was for all remaining passengers together! First time in my experience a full wide-body aircraft boarding was not by row. Predictably, the process was slow and chaotic. Last minute switch from a 777 to an older, non-refurbished 747-400. Entertaiment system contents are still great, but the screen is dim and outdated by today's standards. But I would just fill this as luck of the draw."

Cons: "Flight was delayed."

Pros: "The crew was very nice , offering us often drinks and snacks There was touch screen to each passenger the flight passed faster thanks to the films ... especially i loved the idea of waching a film that took place in new york city when our destinations was new york . Thank you"

Pros: "Friendly staff Food was great Constantly handing out water and drinks"

Pros: "The crew was very friendly and professional"
Cons: "The seat space was a little narrow"

Pros: "The refurbishments of the 777 aircrafts has definately improved the experience. Passengers were given full liberty to the entertainment unit. The one thing that gives that niche to the flight experience are the crew - I must say I have had 8 flights in the past 6 weeks but the crew of this holland airlines have been great on all klm flights. Please keep up the good work - your attitude is everything!"

Pros: "The flight attendants were amazing. Great entertainment system."
Cons: "Seats were a bit uncomfortable for long distance flight."

Cons: "the cabin, the entretainment... nothing looks like a business flight"

Pros: "Soecial attention, tgey suggestvyiubhave some water. Ask yiuvif you are doing fine... All very welcoming. These guys got some pride in their job and that's nice. True hospitality in the air... Makes you feel at home... and they know what they are doing... Professionals!"

Pros: "cheap(?)"
Cons: "everything - absolutely no frills"

Cons: "All good, thanks"

Cons: "space"

Pros: "Puntualidad"
Cons: "Snacks"

Pros: "Good takeoff, good landing."
Cons: "Food very cheap."

Pros: "Not a thing"
Cons: "Timing"

Pros: "Friendly"
Cons: "Food"

Pros: "Crew and service. Comfortable seats."
Cons: "Check in process was confusing as it is done by KLM and not Aeromexico. Bag delivery is taking forever!"

Pros: "La atención del personal cuando estamos hasiendo check in es muy buena excelente actitud para desirle que haser y todo sea más fácil"
Cons: "Es muy bueno que te puedan explicar en tu propio idioma te sientes muy en confianza con el personal y la aeronave está muy bien en buenas condiciones, sigan así excelente Mexico"

Pros: "Well the crew was very kind and helpful and approachable. This is good even though one might not need anything other than the usual but the seemed very friendly"
Cons: "The change of gates and not updated in the chart soon enough so one would go to assigned gate just to realized it has been changed."

Pros: "Very friendly and helpful crew"
Cons: "Getting seat assignments at front desk was confusing and a little hectic"

Pros: "The crew was amazing"
Cons: "Not charge for the extra bag"

Cons: "Even offered a Boody Mary Zor other drinks on the short flight!"

Cons: "I waited in line for over 2.5 hours for ticketing and baggage & was late to board the plane because they would not hurry up"

Pros: "N/A"

Pros: "Todo en tiempo y el personal muy amable"
Cons: "El mapa del avión y la realidad no cuadraba. Al hacer el check in era un mapa y escogí un lugar y en realidad había una fila más."

Cons: "My seat was broken"

Pros: "the aircraft was incredible nice and clean. I loved it!"
Cons: "hello, the only thing I did not like was the air conditioner. It was too high and my eyes got very dried and irritated. From that everything was very good. thank you"

Cons: "Food was cold and mediocre. After flying 6 hours I got up and walked to the galley to see if there was any food and also to get my blood flowing through my body. It was approximately 5 a.m. After standing in the galley for about 5 minutes eating a small sandwich and while drinking my second glass of water, I was told I needed to sit down that I was in the galley too long. Older adults need to move around and get the blood flowing to prevent getting a blood clot. the 3 women stewardesses were busy talking in the galley I guess they felt their privacy and as being invaded."

Pros: "Movie"
Cons: "Seat"

Pros: "service was good"
Cons: "There was no Wi-Fi even though there was signs in the plane of Wi-Fi availability"

Pros: "The service was great!"
Cons: "N/A"

Pros: "The service is great"

Cons: "Nothing"

Pros: "From checking in and the flight attendants are extremely friendly."
Cons: "That we are going for such a small time!!"

Pros: "Everything was excellent!!"

Cons: "Very, very displeased with the care I received from this airline and their lack of communication about the boarding process. Both the gate staff for my flight, the gate staff for other flights, and the staff behind the check-in counters were unhelpful, uncompassionate and seemed to have no sense of "customer care." I ended up missing my flight because of their disorganization, their lack of communication and professionalism, and then, was not helped in the least. I echo another reviewer when I say, "worst experience flying ever.""

Pros: "amazing plane large easy new"

Pros: "The gate agents got me extra legroom in emergency row because i am very tall, at no extra charge. Airplanes were newer, very nice crew, on time."
Cons: "The Mexico City transfer was weird, and inconvenient. You have to retrieve your luggage, go through Mexican immigration, recheck your bags, go through security again, and the layover was over 4 hours. You pay less, but it winds up being a very long, exhausting trip. I will take a US carrier from Quito to San Francisco, Reno or Vegas next time fir this reason alone."

Cons: "Departure was late."

Cons: "The flight gate was never posted on the departures screen, if it were not because we kept asking we'd have probably missed our flight. The flight was also delayed by 2 hours and we were never informed of this...it just happened as we went in circles around the airport."

Pros: "We finally got home. Only 10 hours later."

Pros: "Overall trip was ok"

Pros: "Nothing, they didn’t let me board"
Cons: "The fact they sell you a flight with a connection in Mexico City with only an hour to transfer is ridiculous. Being that this is mexico’s airline they must know it’s a literal impossibility to make that connection. When you arrive they automatically shuttle you into an area to rebook you almost like it’s expected. Then you wait for 8 hrs in a crowded ghetto airport waiting to get on the next flight. When you speak to customer service they talk to you like your a dummy."

Pros: "The flight was smooth and on time. The basic coach seat was roomy. Good selection of in flight movies and TV shows."
Cons: "The cabin needed a thorough cleaning."

Pros: "The crue is nice and friendly."
Cons: "The map for choose seats was diferent than the airplane, i payed for a row with nobody in front and i get one line after that. I only payed money for nothing. The food is poor and not tasty."

Pros: "The seats were not terrible and the crew was nice."
Cons: "The English on board was rushed and I could hardly understand what they were saying. I tried to call TWICE to make sure that I could change dietary preferences because I have food allergies and I was told both times that I was unable to. This is not fair for the price paid for flights. I am very unhappy with the fact that there was food served onboard and that, when I tried to tell the airline what I could and could not eat, that they did not change my preferences or even give me the option."

Cons: "I'm a Delta Sky mile Gold medallion member and not sure why Aeromexico is a sky team member but I still got charge for my one luggage"

Pros: "ON time, friendly, comfortable and there was food."

Pros: "Straightforward and good. Very Timely."

Pros: "The seats were nice"
Cons: "My only food option was ham sandwich and I do not eat ham"

Pros: "The crew were incredibly nice and accommodating."
Cons: "Because it was an older plane, the entertainment options were minimal. The few TV's that came down had very poor quality- grainy and discolored with lines going through it."

Pros: "On time, space, entertainment, service, vessel"
Cons: "The food was unedible"

Cons: "Had trouble getting movies in English"

Pros: "I was comfortable, it was an all Arround good flight, friend Iiness,."
Cons: "Hard to think what I didn't like, since it's been years since I did not get a nice breakfast in other airlines until I flew on airmexico,and did get one."

Pros: "Aeromexico puts delta, United, American to shame. Every time I fly with Aeromexico they have on-time flights, food and drinks included, friendly service and excellent price for tickets. No last second delays or flight rescheduling as happens with US carriers. I'll take Aeromexico ANY day over the shitty US airlines. And for those complaining about info not being readily available in English, it doesn't hurt to learn a little Spanish"
Cons: "They ran out of Corona."

Pros: "Flight was on time flight attendants were very nice and helpful to all needs definitely using this airline again"
Cons: "Plane was a older felt a little more crammed in with it being three row seats"

Pros: "The flight departed more than 90 minutes late. Not impressive. No one ever explained the delay, so poor communication. The food was considerably better than the previous flight. Older plane so no movie selection. We appreciated the fact they did not lose our luggage on this journey."
Cons: "Overall, based on our experience to and from our destination, we will avoid Aeromexico in the future. The people are nice but it is a poorly managed airline. Too many headaches and surprises to justify any discount. We have flown many times internationally and therefore understand things are not always smooth. But there are too many problems with Aeromexico."

Pros: "Nothing. It really was the worst travel experience we've had."
Cons: "Staff at boarding area was rude and disorganized. Plane was worst I've seen. Old with the least legroom I've seen yet."

Cons: "When a flight is scheduled for a customer, connecting flight to another country, I highly recommend you all give customers with at least two hour layover. I missed my flight because I was not informed I would have to grab my luggage and recheck them. This is a nightmare!"

Cons: "You lied to me because the flight was not with Copa but with Aeromexico."
