Last Updated: July 17, 2024

Travelling by air can present a variety of unexpected challenges, including delayed flights, flight cancellations, and other disruptions that can cause frustration and the need for resolution. At AirAdvisor, a trusted platform specialising in air passenger rights, we empower air travellers by providing comprehensive guidance and resources to navigate the complexities of airline complaints.

In this article, we explore making a complaint to KLM and explain how our expertise and support can assist you throughout the process. From understanding your rights as a passenger to discovering the appropriate channels for contacting KLM, we equip you with the necessary tools and knowledge to address any concerns that may arise during your travels with this Dutch airline.

What Can You Make a Complaint About?

You may wonder what makes up grounds on which to make an official complaint to KLM. The good news is you can complain about pretty much anything you felt inconvenienced by as a passenger, such as poor customer care, excessive wait times at check-in or a horribly uncomfortable seat. However, only a select number of flight disruptions legally entitle you to financial compensation.

If you're travelling out of the UK on KLM, for example, you may be eligible for flight delay compensation UK in the event of a delay over 3 hours. Another instance of a complaint that's like to end in compensation within the UK or EU is a complaint to KLM about a flight they cancelled less than 2 weeks before the scheduled departure date.

Aside from KLM delayed or cancelled flight compensation, you may also lodge a complaint requesting a full refund for a cancelled flight, or reimbursement for expenses incurred as a result of damaged luggage.

If your flight was delayed, canceled or overbooked within the last 3 years, you could be eligible for up to €600 in compensation.Check Your Flight

Know Your Passenger Rights

When travelling with KLM, having a solid comprehension of your entitlements as an airline passenger can be beneficial in case you face a flight disruption. This includes familiarising yourself with Regulation EC No 261/2004, commonly referred to as EU261. These regulations serve to safeguard your travel rights with the EU or on EU-based airlines, providing protection in cases of late departures, cancellations, boarding denial, and baggage problems.

Concerning KLM flights departing from UK airports, it's important to consider the provisions of UK261. This regulation aligns with EU261 and ensures that passengers travelling with KLM from UK airports are protected by similar compensation rights in the event of flight disruptions.

By understanding the intricacies of both EU261 and UK261, you can assert your rights effectively and seek appropriate compensation for any inconveniences you may have experienced during your KLM journey.

The Barcelona to Amsterdam flight was delayed, which would have meant that I would miss my connection from Amsterdam to Seattle. So the airline instead put me on a different itinerary of DL169 which caused an overall delay of almost 8 hours.

Offered me a voucher valid at Birmingham international which I did not take or use as I went directly to London in order to catch the Eurostar to Amsterdam instead of staying an additional night in Birmingham and flying the next day. KLM's alternative flight offer was to fly the following morning to Amsterdam via Frankfurt. This was communicated via the KLM app. At the airport I never managed to speak to a KLM agent although I waited in the line for at least 45 minutes. They handed everyone a card with a number to call. I booked the Eurostar myself and took the next train to London to catch that. I arrived home just after midnight the same day. My original flight was scheduled to depart 13:25 so I traveled at least 10 hours to reach my home.

We had a flight with KLM from KRK-AMS and then connecting with AMS-EDI on July 19, 2024. The global outage caused both flights to get delayed by hours each, and with our first flight being delayed we were not sure we would make the second. But upon arrival to AMS we learned the flight to EDI was delayed enough that we had plenty of time to make it. However, without warning, we were denied boarding (without a rebooking) on the AMS-EDI flight, had to call and talk to about 7-8 people before getting a rebooking for the next EVENING to Newcastle, nowhere near our final destination causing us to have to take multiple taxis and trains in the middle of the night. Not only that, we spent hours waiting in AMS with no idea where our checked bag was and were refused help to retrieve it. Only the last people we reached out to helped and gave us a hotel room and some vouchers along with a rebooking (the LEAST KLM could do at this point) and to top it off, our bag did NOT make it to Newcastle! I don’t know if we will ever see that checked bag again. The global outage was not KLM’s fault, but they handled it extremely poorly and with little to no communication and lost so many bags. I know a few parties traveling this day also who did not have nearly as much trouble as we did. Do NOT fly with KLM ever - I surely won’t.

Got told we were given a voucher to use the next day and never got it. Upgraded my seats and ended up on flights that were crampt and no space also located at the back. Only chose klm for in flight screens and ended up with nothing for the whole flight. My rebooked flight was the next day in early hours which meant I didn't have time to sleep before coming back. Then on the rebooked flight it was delayed 1 hour so my transfer time ended up being 15 minutes. Which I made from running but my checked baggage did not. Then arrived at my destination and had to wait a further 3 hours for my checked baggage to arrive. This made a distruption to my travel plans for in warsaw and surrounding cities for my whole trip. I now had to book a hotel for a few days at the same place as i already had booked for but missed since I was so delayed on my arrival. So I missed my event and lost money. The airlines didn't know anything and couldn't give any more than just wait and see if anything happens. When my first flight got cancelled I spent a total of 6 hours in the airport waiting for the then delayed flight and then for my checked baggage to come back. This was all chaos and has made me anxious about solo flying now.

No reason given

Jul 20, 2024
I couldn't apply for compensation via KLM online portal, as it constantly threw up the Manchester flight number, whereas the original scheduled point of departure was Leeds. The informal reason given for the Leeds flight cancellation was that one member of the crew had not turned up. No formal explanation was given. First of all, KLM's rep, ServiceAir, just gave us a phone number for us to sort out the flight ourselves. Only after nagging did they offer us a new flight from Leeds, and then only the next day, with an arrival time of 1815hrs! We had to insist on being offered a flight from Manchester same day, which they did and KLM paid for the taxi. Without hassling them, we would have got no service at all. At Manchester we asked to be put on the earlier KL1032 flight, rather than KL1034, in the hope we could get a seat on the afternoon flight from Schiphol to Lyon. They did put us on the KL1032 flight, but didn't advise that the onward leg was on a standby basis!! Even greater stress, as we only learned that our seats were confirmed ca. 90 mins before departure. Upon request, we were given some food vouchers, which didn't cover the cost of a warm meal. Our request to be allowed into the business class lounge at Amsterdam, on the basis of the huge delay caused by KLM's cancellation, was turned down. Overall, shocking customer care. There were no seats left on the afternoon flight, so we ended up with the AF1799 flight from Amsterdam to Lyon. This was, itself, delayed. We eventually arrived at Lyon shortly before midnight, rather than at 1120am. We missed a formal dinner at a Michelin star restaurant on the Monday evening with our US friends whom we were meeting at Lyon, as well as half a day in Lyon. Our flight back was on the following Thursday morning.
