Cons: "Delays, took my hand luggage into the hold,"

Cons: "This return flight was much better than the flight going to Amsterdam. I believe the biggest factor was the type of aircraft. The old 747 just didn't meet expectations. The newer 777 on the way back was much more comfortable, with better amenities."

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

Pros: "Crew was nice and friendly"
Cons: "Airplane so uncomfortable. Food horrible. Not even available for one of us what we ask for on what was offered. Bad taste and not what can be on a that length of time flight."

Pros: "Crew were friendly and helpful. Moved me up front in the plane so I could make my connection."
Cons: "Not having to walk outside in Edinbur4gh to board the flight."

Pros: "quick/efficient boarding - good staff - good food - easy flight !"
Cons: "the connecting times for klm seem to be very close - if your running late to start - you may not make your next one -"

Pros: "Crew was amazing, seats were comfortable with enough leg space even without choosing extra space seats. It was my childhood dream come true to fly with KLM. It was really an exciting trip for me, just that it was short."
Cons: "Well, for me everything was on point. Those who have never travelled with KLM, I would encourage them to do so and I’m sure they will not regret."

Cons: "Turn the lights on early making it hard to sleep"

Pros: "Service was great as usual. Food was very good and entertainment options were great so you won't have to be bored throughout the trip."

Pros: "Crew was in a festive mood, the meal was unexpectedly delicious"
Cons: "Seats ok, but could be more comfy"

Pros: "The constant smile conferred by flight attendants through the entire flight."
Cons: "The boarding was a bit disorderly. Lanes for zones 3 and 4 were not clearly indicated."

Pros: "Gaps between seats are very narrow."
Cons: "when serving drinks, cabin crew limited to serve liquor only once and it was poor service."

Pros: "Friendly crew! More legroom, good entertainment and food was great! Smooth landings pretty much on time."
Cons: "Boarding could be better"

Pros: "The seat was spacious and the concept of the evening meal being the lighter option was innovative and well thought out"
Cons: "Boarding was chaotic and congested with not much information or order."

Pros: "Good selection of movies."
Cons: "Very small seats with no leg room and very little room on either side. The food was bad - even when compared to other airplane food. Plane is kept too warm."

Cons: "KLM lost my luggage during the layover. My luggage didn't arrive even after the next flight to Prague. Customer service wouldn't give me any idea what flight my luggage would arrive on, nor would they tell me what time my luggage might be delivered to me."

Cons: "Boarding was confusing and disorganized"

Pros: "The aircraft felt clean and quite spacious (decent legroom). Cabin crew was friendly and everything went as expected. Bonus points for the Beemster cheese sandwich (I was totally disappointed when they served the food, but more than pleasantly surprised by the quality of the cheese - I even bought some afterwards, from the Albert Heijn just outside the security area)."
Cons: "Very odd queue separation at boarding. Passengers were divided in 5 lanes, depending on their seating area withing the plane (for a more efficient boarding, I presume) but, by the time we all got to the actual aircraft, we formed another queue in the boarding bridge so it didn't feel like any time was saved or anything."

Pros: "Boarding was as expected, crew & food were ok. Nothing else positive to extract out of this flight."
Cons: "Delayed flight, horrible baggae policy when the flight is actually operated by a partner of the company you bought the ticket from and not the actual company. Dirty seats, no in-flight entertainment whatsoever (not even a magazine)."

Cons: "... ear plugs, masks, good food or even picking seats? I remember when it was all complementary and standard on overnight flights. Oh, and the vegetarian breakfast was unfortunately poor as well. I know you can do better, because you used to."

Pros: "He missed it due to having a 32 minute layover, which he ran all the way to board."
Cons: "he had no choice but to look at the closed door of his flight, and wait an additional 7 hours and they didn't even give him a voucher for food. I'm his mother, I'm currently visiting family in Scotland, so couldn't help him much. I'm pretty disgusting and disappointed by the whole experience."

Pros: "Sandwich was incredibly tasty (although not much filling)"
Cons: "2 hours on the tarmac delayed with no explanation. Uncomfortable seats, no leg room. Poor management of seating, there was enough empty seats to have groups together but they were split up. Drinks served from a communal bottle in a polystyrene cup."

Pros: "Fabulous trip with friendly, helpful staff"
Cons: "Nothing"

Cons: "Missing wheel chairs swrvice lounge far away no food option just lame klm tipique"

Pros: "I personally do not appreciate the food on this leg of the journey Food Ams to Dxb is GOOD!!"
Cons: "The snack & “ solid eggs” in breakfast. Fresh fruit was good."

Pros: "The food was excelent"
Cons: "I have to pay to pay a little more confort"

Cons: "No proper info regarding cancellation. Staff was unfriendly and abruptly responded to passengers."

Pros: "Crew was very helpful.food"
Cons: "Food was not upto the mark."

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: "They were awesome."

Pros: "Professional, friendly service. Punctual, safe flight. Comfortable, spotless airplane."
Cons: "What is there not to like about KLM? I cannot find anything."

Pros: "Short, comfortable flight. Nothing special. Got us where we needed to be without incident."
Cons: "Nothing. This is filler text to meet the min. characters."

Pros: "Flight attendants were friendly, but they only had limited resources to work with."
Cons: "Worst aircraft I have been on in years. No wifi or entertainment, no power outlets, only bad wine/beer for a 3+ hour flight is mediocre at best..."

Pros: "It was a short flight so it was O.K."
Cons: "Boarding was odd. Go to airport early and counters were not open, did on line check in so was able to avoid the self check in at airport. Also self check in luggage seems confusing with no ground crew to help. It didn't affect me but lots of confused passenger."

Pros: "KLM fed a sandwich even though the flight was only 2 hours. The crew was pleasant. Getting through the Amsterdam airport to catch a connecting flight with only an hour to do so was no big deal. Airport staff was pleasant and helpful."

Pros: "Spacious cabins, friendly service"

Cons: "Been non discriminatory"

Cons: "Seat choices that were aisle or window for free"

Cons: "The entire thing was delayed the entire time. I spent 30-45 minutes just on the runway. They only offered biscotti and pretzels as snacks. I’ve gotten cheaper or same priced flights with full entertainment and faster arrival times on other airlines. This was a last resort this time around but I would never take it if I didn’t have to."

Cons: "Flight attendant was exceptional."

Pros: "The crew was great, very kind and accommodating."
Cons: "There was a leak inside the cabin, didn't notice it until after take off. I could not relax for the rest of the flight. Had to pay for bags."

Pros: "No problem with boarding and flight crew. Seating was comfortable."
Cons: "Checked in 1 hour 45 minutes early and our checked baggage did not leave with the plane. Lost baggage representative on the OKC airport was incompetent. Repeated contact information 3 times and still had to follow up delivery with corrected address and phone number."

Pros: "Not much!"
Cons: "Flight was 90 minutes late leaving Manchester so J missed my connection in Philadelphia! After a rebooking I was put on a flight to LA but that flight was also late and delayed getting to the gate in LA so I missed the flight to Seattle"

Cons: "Instead of taking my one half of one ounce plastic cup half-full of wine, the stewad, allowed me to keep it. I love common sense."

Pros: "Not one thing. AA promised us a hotel. No we did not get that. And because I changed my flight on the phone (cause stuck in airport) said we we were supposed to stay there. We were not Compensated with a food voucher. I was supposed leave St Lucia though Miami and I am disappointed"
Cons: "So many ways"

Pros: "Phoenix to Santa Rosa 10 times better than Phoenix to San Francisco then driving the rest of the way."
Cons: "Luggage took a long time to collect in Santa Rosa."

Cons: "Service was excellent"

Cons: "Uncomfortable plane"

Pros: "Nice quick, timely flight."
Cons: "BARELY made the flight..delays leading to it. Ridiculous waiting on the Tarmac."

Cons: "Late departure; horrible breakfast choices( don’t eat biscuits and gravy) so therefore ate fruit and a yogurt. This is first class? The pastries were tasteless; didn’t get headsets until after movie had started. Nothing extraordinary about crew. Wish there were more competitive Airlines flying out of Phoenix— American Airlines disappointments...again."

Cons: "Uncomfortable Old plane with cigarette compartments Unfriendly staff They could not Sit me and my partner together because of the “fate” which was like 700 USD each! Yet they had empty seats and the ability to fulfill the request. It’s sad the low service level, operated by American Airlines booked with British Airways."

Pros: "Our seat upgrade was great. had plenty of leg rooms. Staff was attentive and flight was once again comfortable."
Cons: "Took a while to embark on time. The in flight usb on all of our seats wasn't functioning at all. At least the entertainment portions was working."

Cons: "7pm flight, received flight delayed notification at 11am that day. How do you anticipate a delay 8 hours prior to a flight. Delay allowed me about 10 minutes to sprint through the lovely Charlotte airport. To finish off my trip, American Airlines manages to misplace my carry on that was required to be tagged and stowed. I handed it to the individual right outside the plane to be stowed. How does the bag not get in the same plane?!?"

Pros: "Service"
Cons: "Seats and space"

Cons: "This was an updated 737 with pleather seats and a sleek look inside. But what matters most is leg room for me. There was none. I flew for 5 hours in totally cramped conditions. I loved the page in the mag about seat exercises to keep your leg circulation up. Couldn't bend my knees even. Disgusting"

Pros: "Other passengers"
Cons: "It was terribly hot and the attendants didn’t serve us regularly. The skipped us when we wanted cold water:"

Cons: "Flight to and from AL on American Airlines were both canceled - I was switched to Delta on the ‘to’ trip and was in AL another night on ‘home’ trip"

Cons: "Flight was delayed"

Pros: "Friendly staff great pilots we got up and down safely...."
Cons: "No time to grab lunch all I had was pretzels do you"

Pros: "-Efficient Boarding -Great flight attendants -Communicative Pilots (flight time, number in line on runway, etc)"
Cons: "Did not dislike anything on this trip."

Cons: "There was a lot of announcements on the very early flight trying to get people to signup for a credit card...too early for all those unimportant announcements :("

Cons: "Cramped seats, no great snacks"

Pros: "upgraded to business, which made for a nice ride home."
Cons: "seat and monitor seemed to have minds of their own, but only caused a minor inconvenience I'm frustrated with AA's information on movies, which is questionable and unrealable. For example, the recently released film 'Coco' was listed as PG-13 and not included in the "Disney" category. "Justice League" was listed as R. There are several other examples of misinformation in their movie listings. For parents who use the ratings as one piece of information to guide their children, it would be nice to have correct information when making selections. this problem is not new; it's been this way for over a year now. I hoped that over time they would get it right, but alas, it remains inconsistent at best."

Pros: "N"

Pros: "Absolutely no part of the flight was comfortable or enjoyable."
Cons: "The plane itself was clearly an older model, lacking many amenities I’ve come to expect flying coach. The overhead compartments were too small for larger carryon luggage, and no one on the crew alerted passengers to this. Thus, many passengers had to go against the traffic of those still boarding to find space for luggage. My seat was at the back of the plane so I had to spend close to 15 extra minutes walking back to the front against boarding passengers to find a place to put my luggage. A simple warning from the crew when I boarded would have prevented mine and many others unnecessary trouble simply boarding. During a very turbulent flight, the captain nor the crew made any announcements about turbulence, our safety, or our progress. Also during the flight, one of the flight attendants got into an awkward verbal spat with one of the passengers. Completely unprofessional and bothersome. Additionally, I had fallen asleep when dinner was being first served, but woke up before it was finished. A flight attendant approached me and asked if I’d like a dinner to which I replied “Yes”. The flight attendant never returned with a dinner for me, thus I did not eat the dinner, which I had paid for. Lastly, and perhaps most disturbing, was what transpired when a passenger had a medical emergency. With no warning, all of the airplane lights turned on and a loud “CODE RED” was announced over the sound system. Imagine being a sleeping passenger like myself, during a very turbulent flight, to be suddenly awoken to bright lights and a CODE RED shouted loudly over the PA. I’m not overexaggerating when I say that I was preparing for the worst. A truly terrifying moment that I am certain was shared with many others on board. To make matters even worse, as a flight attendant rushed to find a first aid kit (which she had trouble finding) she opened up the compartment over my partners seat and dropped a passengers ipad on her head. The flight attendant did return to apologize, but it was little consolation compared to the stress and panic the crew created. I have flown many times, and this was easily the worst flight of my life. American Airlines should be ashamed of the conditions they put their passengers in and they have lost two customers for good."

Pros: "Everything is excellent!!"

Cons: "This was a tiny aircraft from Charlotte to Savannah. Our bags were placed into "valet" for the flight. When I retrieved my bag, the handle was broken! Destroyed on a 1 hour flight. This is exactly why people don't like checking their bags. There is no care for other people's belongings. It's bag enough you're packed on these flights like sardines and then you have to worry about receiving your property back the way you gave it to them. Placed a claim, but meanwhile I had to purchase new luggage for my return trip."

Pros: "Smooth flying and lots of respects to the pilots for their dedicated work. The entertainment really works very well."
Cons: "Poor Service. The service of drinks is done very poorly. Really concerned with the attitude. Never need those complimentary drinks."

Cons: "24 hr trip. Morning business meeting- How did my bag not make my flight? I would have carried it on, if I didn’t trust AA to provide excellent service. This is now impacting my business."

Pros: "Entertainment was good."
Cons: "AA lost my luggage for several days. This is unacceptable. It required my wife and I to spend money on items that were unnecessary. We could not obtain good information on whether they were lost or mis-routed. The worry of whether we should buys clothes, toiletries, etc. was a daily concern. Way to ruin a customer's vacation."

Cons: "Briish Airways does not fly to JFK from Edinburgh. I paid for a flight that apparently did not exist. I had to purchase another flight from another airline on top of the flight that I booked with Kayak. I was supposed to fly to my original airport, but I had to fly to a tiny little airport upstate and pay for a bus to get me back to NYC. I doubt I'll see any of that money I lost in the initial transaction..."

Pros: "Crew was nice"
Cons: "Sounds like an ok airline if you fly 1st or business class. Don't be fooled by great reviews"

Pros: "We did eventually reach our destination safe and sound"
Cons: "In flight service on AA was very disappointing. This was a cross-country flight of 5 hours at the dinner hour. The plane was full [ as usual these days ] seat space was tight [ as usual these days ], but cabin service was practically invisible. The two stewards made one pass with the beverage cart, and that was it for the duration!! On a five hour flight!! When I went back for a beverage, the stewards were chatting at the rear compartment. This was the poorest American Airlines service that I have experienced in fifty years. I will avoid them in the future. Don"

Cons: "The crew was late because of an incoming flight they were rude to other passengers and seemed to have an attitude after a long day they made very few announcements but the flight went fast"

Pros: "Their customer service sucks."
Cons: "Their customer service sucks."

Pros: "Crew was friendly and attentive."
Cons: "Better food selection and free internet would be great."

Pros: "The plane boarded quickly and on time, the flight went smoothly."
Cons: "The plane seating layout was crammed. I had to sit uncomfortably the entire flight to avoid cuddling with the passenger next to me. Total sardine can."

Pros: "Flight was on time. Plane was clean. Staff very professional."

Cons: "The seat in front of ours had a box of some sort that took uo the already tiny space for stowing your bag or placcing your feet. In fact, sitting there would have been miserable and my husband had to move to another seat for ite 9 hour flight."

Pros: "The crew was friendly and helpful"
Cons: "Paying extra for seating and not sitting next to my wife"

Pros: "Music/radio was nice at my seat; got into Sacramento early"
Cons: "No gate # on boarding pass, almost missed flight; kind of had to slouch to look out the window; rough/fast landing"

Pros: "crew was good"
Cons: "very little room and my flight from charlete NC to augusta GA was a slob next to me (didn't even fit in the seat) Row 4, was chewing tobacco and spitting in a bottle. It was extremely disgusting, I wanted to vomit the whole flight"

Cons: "overcharges"

Cons: "Our luggage was lost for about 22 hours, we kept getting coflcting information each time we called to check on it. The rental car that was also booked through the KAyak was junk. We requested a mid-size car, they tried to give us an old mini-van that was dented up, we called Enterprise instead and got a 2016 Ford Focus with unlimited mileage for only 15.00 more for the the 5 days of rental."

Cons: "Still waiting to get on it"

Cons: "Could not hear gate attendant. Ticket holders clogged the doorway so could not get thru when group was called."
