KLM should be classified as the worst and most unreliable airline . I’ve never had so much problem as cancellations and rebooking and poor service as I experienced with KLM. They don’t ever care to compensate my loss despite I paid extra for the cancellation insurance. Whenever you call customer service, you are connected to their staff in Philippines and, without being disrespectful to anyone, they cannot speak english and it just add to the confusion and misunderstanding.
This airline is one of the worst and careless airlines and I would not recommend to anyone if you are traveling for business or meeting with tight and sensitive schedule.

My first experience with KLM was a disaster and will definitely be my last. Due to their routing error, my family and I faced significant stress and inconvenience. Instead of offering proper compensation, their customer care team provided empty apologies and rigidly stuck to policies that ignored the real impact of their mistake.

The flight itself was uncomfortable, with no proper space for hand luggage—my carry-on was placed at the door due to lack of overhead space. I was even questioned in Dubai over a visa warning caused by this incident.

Terrible service, poor customer support, and zero accountability. I’ll never recommend KLM to anyone.

I booked insurance with Allianz for my up and coming flight to Jaipur. I then had an accident and was unable to travel. I was unable change the flight. I had to cancel it. Allianz will not process my claim - which took me hours- until I had a specific invoice for the amount of refunded money I would get after the booking fees were refunded. Super complicated. Unable to request this document by telephone or online.

I have called so often - KLM have an English speaking option but each time I called it it was not available. My french is OK too. Then I was told by a KLM staff to contact the exact department via phone for reclamations. When I called it said all the advice was online. So the staff just deflected me with added frustration.

I cannot speak to anyone / or email anyone or upload the information that I need to as each time you go to the specific page it puts up a baggage complaint page ( ?) and the upload document button does not work. (!) Deflect and defend.

I was a loyal KLM Traveller and enjoy the airline. Better than airfrance. I have spent thousands of euros and ...I have to go to Jaipur in 10 days now I am healed. they could of given me a code or a refund code but no... they made me cancel. Now I am owed 780 euros and Allianz are refusing to pay before I have the form that KLM are blocking.

I recently flew to Gdansk from Bristol for a business trip and had an absolutely appalling experience with KLM.

Four days before my outbound flight, I attempted to check in, only to discover that my passport needed at least three months of validity beyond my return date (mine expired on April 25th but needed to be valid until at least April 30th). Unable to get an emergency passport appointment until the morning of my flight, I contacted KLM to ask if I could reschedule. They flat-out refused.

Knowing I wouldn’t make the original flight, I asked a KLM representative if I could book a separate outbound flight and still use my return ticket. I was assured that this was possible. Based on this information, I went ahead and booked a new outbound flight.

Two days before my return, I attempted to check in via the KLM app, but my booking was greyed out. I called KLM again, explained the situation, and was once again reassured that my return ticket was still valid. I was told to check in 30 hours before departure. However, on the morning of my flight, I saw a notice on my booking stating, "As requested, your flight has been removed from your booking."

Frustrated, I spoke to yet another KLM representative, who now told me I needed to send confirmation of my booking for it to be reinstated. I did this immediately.

Upon arriving at the airport, I went to check in—only to be told that I needed to go to the ticket office, which was operated by the airport, not KLM. The staff at the ticket office then contacted KLM directly on my behalf to clarify the situation, and it was they who informed me that I would have to pay a €150 "out of sequence fee” just to board the flight I had already paid for.

Completely shocked, I called KLM myself to get clarification. They reaffirmed that I was not allowed to board the flight unless I paid this arbitrary fee. I explained that I had been misled by multiple KLM representatives and that I did not have the money to pay it. Their response? If you don’t pay, you don’t fly.

With no other choice, I had to call my parents and borrow money just to board the flight home.

To make matters worse, I was then informed that had I booked my second outbound flight after the original departure time, I wouldn’t have been charged this outrageous fee at all—something none of the previous three KLM agents had bothered to mention.

This was an absolutely disgraceful experience. KLM’s staff gave me incorrect information at every step, leaving me stranded and forced to pay an unfair fee at the last minute. Their customer service is incompetent, their policies are deliberately misleading, and their attitude toward customers is appalling.

Safe to say, I will never fly with KLM again. Avoid this airline at all costs.

This is the worst flight ✈️ to chose to fly with. I paid for an unaccompanied minor, they lost my son greencard, his iPad and denied that they were not given on departure. If they were not given how did my son passed the customs without documentation. Have been calling them to retrace the missing items but them keep playing me around, it is so ridiculous and please. If one of you want to travel never chose KLM they are thieves.
