Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

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

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

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

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

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

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Overall flight was fantastic.i really enjoy the whole journey .

Little more legroom would have been nice. But it's a very short flight, so it was fine really.

Short flight, some waiting to board, but no issues and no frills.

No staff at the gate and the flights were not posted on the board so we missed our flight. Horrible experience. Be VERY careful flying Norwegian. Super limited ability to communicate with their slim staffing and restricted hours.

Tickets were cheap but it says no where that food was not included, I travel Austrian, Swiss and Turkish airlines all the time always food is included, never flew Norwegian again

Pros: "Nothing,except I got to my destination safely"
Cons: "Everything.They don’t ever offer you WATER in a 10 hour flight!! Check in crew rude. Attends dismissive to rude."

They cancelled our flight home less than 24 hours before it was supposed to leave. It partially ruined our last day because I was on the phone trying to get 5 people home and the stress that it causes. We still arrived at the airport with no definite flight plans. The actual flight was good but my kids really misses the kids meals I had ordered for them which obviously didn’t make it to the new flight.

Very unfriendly approach to me when you rescheduled my return flight due to your delay. No help to address my health concerns because I am diabetics and had orthopedic problems. No clear explanation where to clear customs. I had poor customer service

Maybe more diverse entertainment. Although the inflight cameras were amazing 10/10

I was pleasantly surprised as it was my first time flying with them. The seats were comfortable with more legroom than usual. The service was great too! The entertainment was good but could use a few more new movies.

Nothing special or negative. Pretty typical flight…no freebies in the way of food etcetera, but none were expected.

They were all bad because SAS was at fault and cost me my time. I will never fly SAS again.

You cost me my time and did not compensate properly. Gfy.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

I experienced trouble with the automatic bag check in. When I scanned the baggage tag I received, things were fine as the conveyor belt moved forward then abruptly stopped! My luggage traveled about 4 feet and I had to reach over a barrier to retrieve it. I went to another scanner position and when I scanned the SAS baggage tag, the screen told me it could not continue!! I went to another scanner position agent who had me put it on the conveyor belt by her & somehow sent it down the belt. I flew from Bergen to Oslo with a two 2️⃣ hour layover before connecting to LHR. My bag was NOT on the flight. I had no clothes for the next day when I flew to Boston. I filed a Lost Bag report and waiting for updates.

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

Their customer service needs an overhaul. I wish we could access them and the could be more helpful. Also, the website has been crashing and I had numerous technical errors. My flight was cancelled and we spent so much time trying to get help because the tech was failing.

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

all fine - did not have food - there was no entertainment

Was very good the flight, 15 minutes late,but was very ok!!!😊👏

On time was excellent, not serving any water and deliberate seatings apart is deplorable.

Delayed delayed delayed and then cancelled very late not allowing for too much time to find a room for the night
