Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.

Brand new plane lots of room the snack was very flavourful and enjoyable

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

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

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

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

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

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

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Service was professional and quick. Premium economy seat was comfortable given the class

I'm a United 1K member and have ben for 10 years. The gate agent had no control over the boarding process and had us passengers queued for hours as delays were announced. On the plane, the overhead air nozzle was broken so col over was powering through on me and the passenger next to me. Not a great experience for a million miler on United. Feel free to contact me. Josh Smigel - DM426089

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

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 paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

At least one soda free, felt like I was nickeled to death.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

When you consider the price I ended up paying for everything. This was not a good deal! I had no idea that this airline had changed to a bargain basement no frills airline. So, it was disappointing to have to pay for every little thing. The only thing included was water and coffee. You have to pay for everything else! So I just felt nickel and dime.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.
