It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Flight was on time, staff are friendly and helpful onboard.

Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

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.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Short flight, crew and staff very efficient. Over all good flight experience.

Once boarding started it was pretty quick. Food was inedible; cold and salty..

Horrible Flight significantly delayed. Not due to united issue. But trying to rebook connection flight and get information about overnight accommodation was difficult. Agent did not seem to care or have any interest to help.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

Would have preferred a better food menu. Other than that, no complaints.

The crew was really nice. The plane seats were kinda small even for a 5’6” / 158 lbs person.

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

CANCELED LESS THE. 24 HOUR BEFORE WITH NO FOOD AND NO PLACE TO STAY

Flight was canceled due to labor dispute. Their customer service said I might be ok since strike was on sat. and I was flying Friday. The next morning it was canceled. It can ruin a trip and add stress.

No room when you sit. Fell very cramped. Food was only ok. Service was acceptable. Entertainment system was very buggy.

I will never fly Air Canada again. 5 hour delay due to plane problem which could have been fixed while plane sat empty. We offered a $15CAD voucher for dinner due to delay, BUT that is NOT Even enough for a hamburger. Air Canada rebooked my 87 year old mother on an onward flight in Munich with NINE HOUR layover without rebooking me on same flight. Air Canada apparently cancelled my onward flight as I was offered a refund for the Lufthansa leg from Munich. Fortunately, Lufthansa Service Center staff was very helpful rebooking us both on same flight which was one hour earlier, so only 8 hour layover. Lufthansa airport Mobility staff as well as plane crew were awesome and extremely helpful with wheelchair support. Spoke with others who were on same flight from YYZ to MUC and there was at least one other person that was not rebooked onwards (from Munich to Hamburg) by Air Canada but was able get support frkm LH Service Center staff. The Air Canada plane crew was very helpful, so the overall issue is Air Canada systems, and gate agents that have caused multiple negative issues on AC836 YYZ to MUC on May 18th. Similar to what others on this flight have said, I will NEVER, EVER, NEVER AGAIN fly Air Canada. And I've likely flown over 1 Million miles with them, with lots of miles in Business Class and have held Elite, and Super Elite status.

Very smooth flight and the crew members were very welcoming.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Well considering they didn't transfer our luggage once we arrived in Frankfurt to our Air Canada SUCKS!
