Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Klm start boarding while somw air issue in the plan

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

Loved the courtesy and punctuality. Very professional and most importantly on time.

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

I did wish they would give us the entire little bottle Bailey's instead of just have 1/2 bottle at a time

My layover in Vienna was supposed to be 35 minutes but because my flight was canceled I had to wait in the airport for an additional 8 hours.

Very limited legroom in a 10 hour flight.very old plane.

The flight was delayed for 30 minutes with no apparent reason. There is no entertainment at all, and no USB or electric outlets for charging your phone or tablet.

They had me unpack a handbag 2 lbs overweight into another handbag 8 lbs underweight for a Bible.

My flight was canceled and even though I paid אם KAYAK you didn't even answer me and obviously didn't refund my money. I will never buy a ticket through you again.

Accessibility serious problems in Viena airport making it seriousely difficult in in-between gates and boarding travel. Pretens of breakfast and service care in the economy pathetic.

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

They can my date of travel and let me standard in Istanbul for three days stop over and only pay for one day in a hotel with only one breakfast for three days.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

it was a terrible experience. after 4 hours at the gate the flight was cancelled. the airline offered to rebook the flight for 26 hours later. Our team was travelling for an international competition. They missed the competition because the airline delayed them for over 30 hours. We already left the airport but the next morning we received an email stating that we were rebooked for a flight which was another 24 hours later after the already rebooked flight. We bought a ticket on Kayak. The reservation was delivered with a logo Airfareassist. I used Kayak services for over 20 years and assumed that I was dealing with a legitimate organization. Once the flight was postponed for over 40 hours, I learned that Airfareassist is a 3rd party agency whom kayak routes business to without notifying me, the customer. While I was entitled for a full refund, which was confirmed by the airline, Airfareassist only offered a partial refund and kept the difference. Kayak has failed to do a due diligence on the 3rd parties they do business with. As a result I will never do business with kayak again and am filing a complaint with the BBB and the Secretary of Transportation. This is a pure fraud and its unacceptable.

Worst experience with boarding once we left the wheel chair even traveling business we had to wait with all the crowd for the bus to take us to the plane then climb the stairs with our bags When you pay extra for comfort and convenience and you don’t get any is disappointing

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

The best airline for international travel in terms of value you get in business class (service/cost)

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

Crew was outstanding, helpful and friendly. Food is deteriorating. The snack at the end of the flight was not good, a greasy moosh of toast cheese snd other unidentifiable ingredients. Coming from Germany a pretzl with butter would have been better. Entertainment had a great selection.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Overall, the service was excellent, the crew verry professional, and departures and arrivals were perfect.

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

It was good. Couldn’t Check in online and select seats

It was great. Enough space and room for legs . Great service to.

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

We were in business class and I had seat # 1. This was a night flight and after dinner was served, lights were dimmed and I went to sleep. The crew were loud and noisy so I didn’t get much sleep. I expect the crew to enjoy themselves but would Appreciate some decency in staying quiet while the passengers sleep

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Well unfortunately our connecting was cancelled and next flight delayed. Was in airport 9 hours. Flight itself was good. I’m sure it was a FAA problem.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

Logan gate staff was unhelpful. Arrived early, come to find out the airbus scheduled was reassigned and I did not have a seat. The desk agent spoke to his supervisor who instructed him to give me a boarding pass to get up to gate area, he was polite. At the gate the fellow was sitting to the side with two other BA staff . I asked him if he could help me, his answer was” we are on a break, we are closed” then turned his back. I am almost 70, drove 4 1/2 hours to Boston and had been looking forward to this trip for 5 months. I have worked in service many times in my life and this is not how it is done. I eventually (1/2 hr) before boarding was able to get a seat. The rest of the flight experience was unremarkable.

The boarding process was chaotic at LHR and the seat was not as comfortable as other airlines....
