Klm start boarding while somw air issue in the plan

Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

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.

You should not have to pay for WiFi in business class

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

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.

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.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

There was no room in the seats, smallest room we've ever had and the food was awful.

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

This flight was of exactly the same high standard as the outbound leg, exactly a week earlier - except that we didn't have any food or drink because it departed at around midnight.

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

I liked how they looked after couples by providing a row of 4 seats if available.

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

I believe it was short flight in plane I understand not that much compared to other airlines but weighting for checkin was too long need extra person for checkin or Atleast someone to let the customer knows don’t worry someone will be here shortly.

Nice to have reclining seats for a change and great to have internet access

Tivat airport really needs to up its game W Eurowings needs to provide support at luggage collection

Delay after delay: no information besides what my Kayak app provided was provided about the delays. The plane was at the gate. Also, the gate, 100A, was incredibly warm, and the sun was beaming in. Boarding was disorganized with no groups announced.

Kayak - EDreams - Eurowings need to define clearer the hand luggage terms. I asked for add. hang luggage got charged by Eurowings for having add. hand luggage that was not included in my booking. I travel alot! I know the size dimensions never paid twice for hand luggage and cannot chase Edreams or put Eurowings in the wrong. Also there was severe delays on this flight. Issue getting bus on arrival and missed connections. Unfortunate will not use Eurowings

We checked in 4 luggage and only got 3 back & lost our 4th luggage. Our flight was from berlin sept 22. We arrived Copenhagen but only received 3 luggage. Missing 1 still 24 hrs after our arrival and our Cruise will be leaving tomorrow 9/24/2023. This is the second time that our luggage gets lost/delayed in Copenhagen

No food on plane.. flights scheduled 55 min..everything is very expensive on aeroport

Filthy plane, obviously not cleaned properly between flights, food crumbles in seat and carpet

Smallest seat I have ever seen. And they had a label with more Legroom but in fact where really tiny.

No cancellations but one flight delayed due to arrival airport industrial action. Comfortable

I was held-up at boarding by rude employee who insisted that I had to wait until all other passengers had boarded the lane before issuing me a boarding pass so I can board the plane. I could not check-in earlier and get a boarding pass since I had flown directly from Dusseldorf.
