Boarding took less than 20 minutes total. They offered free snacks and drinks soon after cruising. They offered more refreshments an hour before landing. This was a 3 hour flight. I haven’t seen this post-COVID. I will be flying KLM more often. The cabin was clean and flight attendants were very nice.

Boarding took less than 20 minutes total. They offered free snacks and drinks soon after cruising. They offered more refreshments an hour before landing. This was a 3 hour flight. I haven’t seen this post-COVID. I will be flying KLM more often. The cabin was clean and flight attendants were very nice.

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

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

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

Horrible experience. They delayed our flight 7 hours!! We had to seat at the airport with kids on 4th July all day!

The flight was delayed an hour and a half while you tried to fix the plane so I missed my connecting flight in Chicago. In Chicago, it took an hour to get the luggage. Then the conveyor belt was broken where I have to transfer my flight from an international flight to the continuing flight so I had to carry a large suitcase through the airport. The elevators were broken in the airport. I paid people to carry the luggage for me up the escalators in two different areas. The person who helped me get the new flight was outstanding. The temperature in the airport in Chicago was horrible. We were all sweating. It was the day from hell. That was after two hours in a security line in Athens. I have TSA pre-checked and global entry and I still waited. Two hours in a security line. Something has got to be done to stream line this service. After I’ve been through all of that in Athens, why do I have to go through it again in Chicago. It was the worst travel experience I have had in a long time. Your bathrooms have gotten so small that you can hardly get your butt on the toilet. You’ve taken the airspace out of the inside of the top of the toilet. It really makes for a miserable experience. Also on a 4 1/2 hour flight from Chicago to Los Angeles. The only thing we’re given is a bag of pretzels. REALLY!!

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

We were Polaris passengers and found the service poor. The food was ok but the flight attendants were not attentive and rushed the service.

Flight was canceled and United offered zero assistance. Left many of us in an unsafe situation
