Pros: "A flight was delayed due to weather conditions and we had to sit in the plane for almost an hour, BUT information sharing from the Capitan was sufficient and on-time. Very good job from pilots. Leg room in economy - I was positively surprised, very decent leg room! Thank you for providing it."
Cons: "I flew economy and all was good and appropriate to the level."

Pros: "Crew good and seat OK but not exceptional for business class"
Cons: "Food was average - main course could have been better. Range of movies ok but not great"

Pros: "Almost everything, especially the crew."
Cons: "Don’t feel like anything should be better to be honest"

Pros: "Pleasant crew. Appropriate and efficiently served snack."
Cons: "Boarding and disembarkation were slow."

Pros: "Flight and the crew!"
Cons: "Staff at the airport pushing you to upgrade to first class but not making it clear only the first trip from Athens to Amsterdam which the first class uses same uncomfortable seats as the economy to pay extra 130 euros ridiculous airfrance stuff! I should have flown all the way to NYC first class!!!"

Cons: "Flight on time would have been good when you have a late evening arrival. Long wait for luggage at Birmingham airport."

Pros: "The crew was attentive and the seat at economy comfort was comfortable at the “ok” level. It needs much mor3 to be super comfortable. The plug for the headphones was a mess! It was NOT possible to watch a movie and hear the sound too! I gave up! Not a great offering for the extra dollars..."
Cons: "So many things! Starting with the way assistance in the airport is offered to travellers with mobility issues! This is an important issue that needs to be revisited and changes for better service to be made!"

Pros: "Cabin crew very pleasant"
Cons: "Lost our bags, little sympathy from staff"

Pros: "Very little if any."
Cons: "Aircraft was not very clean,the staff seamed quite harsh at times when speaking to customers. The food was really quite poor but it was a short flight to be honest. Overall not as pleasant as the China Southern flights. I would not like to choose them again unless i had to."

Pros: "The crew were pleasant"

Pros: "Arriving more or less on time"
Cons: "Crew is awful. Disrespectful desinterested in customers find themselves very important. No service mentality whatsoever. No respectful airline would hire such arrogant self centered personalities in a service role"

Pros: "Staff at Schipol airport were lovely and very helpful. Cabin crew were friendly and efficient. On board snack was nice."
Cons: "Elbow room is a little bit awkward and I didn't get to sit next to my fiance WE will still definitely recommend KLM though!"

Pros: "The cabin crew, the flight and communication and the cleanliness of the plane."
Cons: "It was really unclear which desk to use at Birmingham airport to check in. It was extremely stressful for a first time flier as I had no idea what to do - the desk location wasn't marked clearly and when no staff were there it wasn't clear that the desk was open."

Cons: "There weren't too many options. The movie selection was very limited and the tv show were over 20 years old in some cases"

Pros: "Crew was friendly, and the food was better than the usual KLM fare."
Cons: "The "new" seats were hard and uncomfortable. Avoid any kinds of seats near the bathroom in a configuration with 3 abreast next to the windows. The "aisle" seat is essentially a "waiting area" for the rest room."

Pros: "The constant supply of food that was offered to you. The crew was nice and always helpful."
Cons: "The process of boarding in Amsterdam was not organized and felt more stressful than it needed to be."

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: "I ended up getting home with less delay than originally predicted. I guess that's a good thing Also delta customer service was super polite and trying to help when I called"
Cons: "Delay again... seems to be pretty frequent on KLM flights at least on the ones I flew with in the past 4 years... this time it was 3hours wait due to a technical issue... no alternative flight option and we ended up getting a very old plane as a replacement. In addition people at info terminals are disorganized and not kind at all.."

Pros: "On time."
Cons: "Claiming that the plane was completely full (which it wasn't), They forced just about everyone to check there carry ons. When we got on board, there was plenty of overhead space. Supposedly, we should've have been allowed a carryon and a personal item."

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: "La ponctualité."
Cons: "Variété des boissons proposées."

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

Cons: "Kayak updated me that my flight would be late. It wasn't. Missed it had to pay $700"

Pros: "It was very comfortable and pleasant."
Cons: "Could be a little better the service, the dinner was late"

Pros: "Crew was very friendly. Food was excellent"

Pros: "In flight entertainment was great"
Cons: "seats very uncomfortable, boarding was a mess in Paris, priority luggage was annoying and made us miss our connection flight (as well as numerous delays)"

Cons: "No room, boarding was slow, zero bag or legroom"

Pros: "Flight crew, pilot,food and entertainment options were great"
Cons: "Baggage took a while to reach baggage claim but maybe a bit impatient after a long day"

Pros: "It was a nice plane and boarding was well organized."
Cons: "I was assigned a middle seat, if not for that I would have given a higher rating."

Pros: "The size of the plane was nice. They had a good move selection. The vegan meal I was given was great."
Cons: "It was loud, cold, the food was just okay at least my vegan meal was the bomb but it would have been better had when we booked the flight it allowed me to also choose this option for my husband. Since he is vegan as well."

Cons: "Leg space."

Pros: "Direct flight from Indy to CDG is great. The plane was not so full, so I hope business improves so we can keep it going. Very smooth flight, with good and friendly crew."

Pros: "Everything!"

Pros: "Boarding was on time"
Cons: "flight was delayed by 20 minutes Boarding got me through Sky priority quickly. Had to then wait in the boarding tunnel as the cabin was not ready. large queue Seats were exactly the same as economy so offered no added benefits apart from the meal on board parked in a distant area of the terminal and had to shuttle bus to 2E which meant a very tight transfer"

Pros: "Standard on most parts with pleasant staff"
Cons: "Flight was 1/2hr with poor pre-flight communication on the topic. Food wise, the chocolate cookie was better than nothing...but a little savory snack would have been nice."

Cons: "no vegeterian sandwiches very disappointed"

Pros: "nothing"
Cons: "very old planes we waited 1 hour to drop our bags as their belt had an issue we had to pay extra 70 pounds to reserve a baby cot on the plane"

Pros: "Boarding and punctuality."
Cons: "Lagos boarding with rather annoying wait due to repeat hand check. Perhaps added security carried far."

Pros: "Short, lots of leg space"

Pros: "Great crew"
Cons: "Food could be a bit better. White bread is unhealthy."

Pros: "It didn't take longer to board! Crew with great attitude Take off and landing were just great"
Cons: "My sandwich, it contained too much pepper, I mean too muuuuuch My narrow seat No entertainment"

Pros: "leg space in plane"

Cons: "The crew was not very polite."

Pros: "There was enough leg room"
Cons: "The food was not very nice and the aircraft was really cold."

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

Pros: "The boarding process was smooth and the crew friendly. Flight ran on time."
Cons: "Unloading the baggage took over 90 minutes, and there was no explanation for the delay and nobody from Air France in sight on the ground in Boston."

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

Pros: "The lounge is great, however the food is substandard to nearly every other lounge that I have used."
Cons: "The food on the plane is even worse, The staff were ok but not overly going out of their way to help with any issues, also they could at least pretend to smile."

Pros: "All female crew in the cockpit - awesome."
Cons: "Non reclining seats"

Pros: "Efficient boarding. Interesting hot food. Entertainment variety very good."
Cons: "Business class seats hard. Did not flatten out for sleep."
