Cons: "My husband's display controls didn't work. We didn't ask for help as he planned to read anyway."

Cons: "JetBlue is amazing and my favorite airlines for domestic travel."
Cons: "clearly communicate delays. We had no idea what was happening or what our options were."
Pros: "Boarding was fast and easy but that may have been because it was a small plane."
Cons: "After landing we sat on the tarmac for 2 hours! This is unacceptable. The gate was occupied by a plane having mechanical issues. This was the second time I have flown JetBlue and the second time I’ve had to sit on the tarmac for hours because of some sort of issue. Never flying JetBlue again if I can help it."
Cons: "Nothing. The best airline I've flown across the board."

Pros: "Attendants were very pleasant and helpful"
Cons: "The plane was extremely cramped as the seats reclined so far back that it rested on my knees. It was extremely difficult to keep my seat back up which created an uncomfortable angle for my back on a 9 hour flight. The cabin was extremely warm and there was little airflow. The airline also lost our luggage"
Pros: "Same as above- wonderful crew, smooth take off and landing Very pleasant flight attendants the entire flight Service was great"
Cons: "Again / wish all airlines had more comfortable seating in economy clas"

Pros: "I like the way they take care of their guests, I have 0 complaints"
Pros: "Comfortable seating, pleasant food and entertainment."

Pros: "Everything was easy"
Cons: "Business class seats are snug for big people compared to other airlines"
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: "Premium economy was perfect, smaller cabin with less people, great flight."
Pros: "Crew was super helpful and kind. Pesto pasta was the best airplane food I’ve ever had in coach."
Pros: "It was all good glad the last leg of the trip was pleasant."
Cons: "The unfortunate delay prevented me from attending my grandmother’s wake. Fewer delays would be helpful."
Cons: "Announcements were too loud in earphones (could damage ear drums) and entertainment was turned off while waiting 30 min for the gate to open."
Pros: "The crew really kept us updated on the many delays."
Cons: "There were SO many delays and they kept changing. At one point we got on and off the plane."
Pros: "Delta does an overall nice job."
Cons: "Food is OK. Service is friendly though. Comfort + was nice. Bathrooms were not great, smelled, could use a refresh."
Pros: "Nothing."
Cons: "Flight was delayed 2 hours. Even though I had carry on, they checked it and this made me waste my time at baggage claim rather than gate checking. Flight attendants were miserable. Power supply didn’t work at seats."
Pros: "The seats were ok."
Cons: "The flight was delayed over 3 hours so I missed my connection in Chicago to Seattle. I’m now stick in Chicago overnight and have to be on a 6 am flight tomorrow. The Delta staff at LaGuaurdia was extremely rude and not helpful at all. Hate Delta......"
Pros: "Entertainment choices were plentiful."
Cons: "The flight attendants were borderline rude. No eye contact, no smile, not helpful when asking a question (overhead compartments were full in my section; I asked what I should do, response: „ I don’t know either“ and walked off. I went to find a spot further up the aisle..."
Pros: "Fast boarding, friendly crew, and comfy seats"
Cons: "It was pretty bumpy and a few times we changed altitude very quickly"
Pros: "I loved the flight attendants and the desk staff everyone was so friendly and made me want to travel delta again."
Cons: "Delta doesn’t offer military spouses free checked bags and I found this out at the airport. It was disheartening, but at least it’s Delta and not the airline that is supposed to represent America."

Boarding in NCL is really bad. I'm sure part of that is a directive from the airport that KLM can't change but part of that is due to KLM policy. NCL doesn't announce the gate of departure until 30 minutes before departure. However, when you arrive at the gate area, the gate agents file everyone into one long line and everyone boards from one line at one time. This line can stretch for 200m...easily. There is a separate line for groups 1 and 2 but you don't know it until you get to the gate area and agents don't announce/advertise it. Everyone else is grouped into one line. Are you in group 3? Doesn't matter...you board with group 5. Traveling with a child? Tough luck...you're stuck at the end of the line and board last. The last part is very annoying because none of the gates at NCL (with the exception of 1 used by Emirates) has a jetway. To board, you must leave the gate area, walk downstairs, walk onto the tarmac and walk up stairs to board the plane. Highly challenging if you're traveling with small children. That boarding process begs for a concession to allow people with children to board first because they will need extra time. But there is no such policy. Just a really horrible boarding experience all around.

Pros: "Crew was great, on time flight, clean plane."
Cons: "Entertainments options were shockingly few. Honestly have not been on a plane recently with so few and limited options of TV series and movies. I was extremely surprised. Wish I had know and I would’ve had more options for my family."
Cons: "The airline lost my suitcase and deliver it only 72 hours later... They refused to give me proper compensation for items that were broken..."
Cons: "Boarding at Florence is always chaotic but this isn't within the control of KLM or their crew."
Cons: "It's KLM. What else do you need to know."
Pros: "Nothing"
Cons: "Transavia does not serve anything complementary, not even water. A flight between two countries that is five hours long must be better than this. I was not aware of Transavia doing that before I booked. I will never fly with them again"
Pros: "Information sharing by pilots and crew. Economy class leg room is good."
Cons: "All good up to the level"
Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."
Cons: "Keep the temperature at a more reasonable level. Blankets + two layers of clothing was definitely not enough."
Pros: "15 years ago I told myself not to fly Delta anymore. But these 2 flights Detroit to Amsterdam and back changed my mind. I enjoyed the flight very much and I'm looking forward to the next one."
