KLM Royal Dutch Airlines Reviews 

Impossible to log into web page or phone app. You just receive an error message "Due to technical error ... bla-bla bla" or the verification PIN arrives several minutes later and you will be told: "This is not the right PIN code. Please try again." Tried it a lot of times with no success.
Once again wasting time on manual check-in in airport.

Reading the reviews of other victims of this airlane makes it obvious that the company does not have any reliable support or customer service whatsoever.

No empathy from KLM at any given time: not on our way to Japan when unexpected matters happened (even rude reactions from female staff), nor when they canceled our flight back very last minute, and KLM is very difficult to contact.

Thieves…

I requested a cancellation. They cancelled my flight and paid me 50 euro of my 1000 euro ticket back.

I immediately contacted their support and asked to reverse this I would rather keep the ticket than lose all of my money.

Of course they responded that I should have read the policy and they cannot undo it. And they just protect themselves with this and have no heart for their returning customers.

Digraceful. How large companies like these know the small fish won’t take legal action. And how you get away with it..
I am curious what your books say about where this money is from.

Extremely disappointing experience with KLM – KL627 / KL621 (April 10, 2025)

On April 10, I boarded KLM flight KL627 (AMS–MIA) and sat on the tarmac at Schiphol for over 3 hours with almost no information and just one bottle of water. Eventually, we were told to disembark due to a technical issue. After standing in chaos at the service desk for 4 hours, we were rebooked on KL621 (AMS–ATL).

That flight also turned into a nightmare. Due to congestion at Atlanta, we were diverted to Charlotte (CLT) and kept onboard for over 3 hours, without updates or proper care. We finally landed in ATL with a 5-hour delay, only to find no staff, no support, and closed desks. At 3:00 a.m., KLM’s phone support could only tell us to “find a desk.” We had to book our own last-minute flight to Miami to avoid missing our cruise.

Total delay: 38 hours.

KLM’s claim process is non-functional — the website doesn’t recognize the booking, and phone support is useless.

Disorganized, unresponsive, and indifferent. KLM no longer lives up to its reputation as a reliable airline.

Wish I could enter a no-star review. The is absolutely the worst airline we have ever been on. We traveled as a group from California to Amsterdam. No online seat maps had to go to electronic kiosks only to be redirecteded the service counter.we walked to the counter and noo e was there. A baggage handler said, “Yeah they won't be here till 11.” After an hour’s wait…finally we got our baggage checked and then found which gate. That was only the beginning of the story. Suffice it to say - don’t fly KLM, if at all possible

After nearly two months, submitting the same information six times, finally KLM reimbursed the expenses that I incurred having to deal with one of their cancelled flights. They claim the flight was cancelled due to bad weather but both the departure airport and arrival airport weather was fine. They absolutely deserve their shocking Trustpilot review - it seems they deliberately make it almost impossible to make a legitimate expense claim that they are legally responsible for. By far the worst airline I have never flown with. Avoid at all costs.

KLM Airlines, as Amsterdam Airport is massive, I arrived on gates for bristol uk,just 10 min before flying, faced on closed gates, bare on your mind the boarding screen absolutely confusing,different from normal international Airport,no help from counter ,no guide at all ,said Go upstairs !!
Transfer offer me to pay€1000 replacement flight same night or €721 tomorrow flight !
No help or support with stressful and anxiety for customers, not in their policy!
Trouble was KLM sms me to checking my cabin suitcase as flight is full,I did check in on departure and now if I want to get my cabin suitcase back I have to PAY€400 ,Shocking! No moral!
I hade to pay €400 to get my cabin bag back and go with cheap flights or pay €700 and sleep in Ams airport or £1000 flying same night. No benefit of travelling with them, bottles of water/biscuits on plane couldn't count as good costumer service .

NO RECOMMENDED,go Turkishair, fake high rank airline with silver tongue /shiny counter.
No actual costumer care and support.

Please don't answer my feedback with your careless sorryness and apologies for inconvenience.

DO appreciate your stressful passenger who missed flight and missing to be with wife /husband/partner children.

The problems that occurred on a trip from Heathrow to Aruba:
On way out lost my luggage. It took 2 nights to find it and during that time no-one from KLM would talk to me or communicate the issues.
I had to collect my luggage when it arrived at the Aruba airport incurring further taxi costs
On return flight they changed my business class seat without communicating with me. That said as they had sat my husband and I together I accepted it. On arrival at Aruba airport the check in advised when we arrived at a short stopover, 1 hour into the flight, we would have to change seats and would not be together!

Honestly this airline has no ability to be organised and has treated me with complete disrespect

Luggage was not loaded onto connecting flight. The good side is that they KLM were pro-active in letting me know and will be on the next flight. It was on the next flight and has arrived.

I contacted KLM that part of my content was important for me to work with my customers.

The reunion with luggage was handed over to a courier.

I have tags on my luggage and can see that my luggage has been stationary at the airport for 16 hours an no attempt by courier has been made to contact me.

It seems that the courier doesn’t realise about customer service.

So now I also need to buy new clothing. If the courier was good I would have not needed to do this. This has also placed additional cost on KLM that could have been avoided.

Money,Money,Money!
I got shocked when I checked in.
I wanted to change my seat from a window to an aisle, even more back side ,but I have to charge 6€ extra! Nowadays they fix you somewhere to sit and you can never choose any more ,only you pay more money .
The plane ticket is already expensive enough , but they want more and more….what a shame

Travelled business class with KLM from London to Aruba via Amsterdam. Our bag did not turn up and their customer service is abysmal. The numbers either don’t work or, if they do, the staff are unhelpful. You can’t track baggage on their app if you’ve flown from London and their website assistance is woeful. How can an airline be this incompetent?

Your smartphone app is worthless, no chance if you want to change seat or check-in, even though they tell you to use the smartphone app, you open your app, you see your ticket, but it says “Check-in not available”!!!! And no chance to click anything to change the situation.
On the other hand, one of the participants (but not all the participants) received an e-mail with a Link to enter the system from this Link. After 2 hours and a lot of manipulation and data entry, we were able to make the Check-in, 2 of us made the changes for our spouses, i.e. 4 people out of the whole group, the others couldn't do anything.
I helped another couple make a seat change on their Smartphone. They have iPhones that I'm not familiar with, while I use Android (Samsung) and of course there are differences and it's tedious.
Making changes on a Smartphone is not at all the same as on a PC!
In short, Air France and KLM are specialists in annoying their customers!
What's more, their flight attendants are more into decoration than service.
In any case, it's easier and more efficient on many other airlines.

I had the pleasure of flying with with KLM on the Monday. Between Amsterdam and Hamburg my luggage was lost. Today is Friday and I still haven’t gotten my luggage. Maybe tomorrow who knows. The courier company very unprofessional, they just chose to not answer the phone. I guess it’s easier then facing the problems at hand. I’m on a day rate and I’m loosing money every single day my bags are not here. I guess KLM don’t really care about ppl. As soon as you land. Everything else is someone else’s problem. I keep getting promises about deliveries and return calls. But it seems that “anybody” is expecting “somebody” to do it which resolves in “nobody” does it. ATM I’m beginning to give up of ever gitting my bags returned to me before I have to go home, in a little more than a week. Which is great, because then I spend 16 days away from home “working” without earning a single penny. I think the way this has been handled, is totally unacceptable. I think in many ways I should be compensated, bare minimum informed and updated about the current status. Then again I don’t really think KLM cares. It doesn’t really seems that way. I get a lot of empty promises and then nothing. I’m not to sure if this is how coperate thinks costumer care works. It might be a strategy from their side. If so everyone is doing a great job. If caring about costumers is a priority. Then it’s not really looking to great. I’m a frequent flyer. I fly 3-4 times or month. This is the longest I ever waited and it’s the worst experience I’ve ever meet.

In over 50 years of flying all over the world I have NEVER dealt withy any company as rude and unkind as KLM. We had an original flight with KLM changed by them to involve a one hour connecting flight through Atlanta (from Costa Rica) What they failed to tell us was that would require an ESTA visa. At tiny Liberia airport in Costa Rica they were unable to put us on the plane without the ESTA. We applied in the airport, paid 600 dollars for a quick turn round, but still didn't get the ESTA in time to make the flight. Delta said that to get new tickets we had to speak to KLM. Which I did, and they were poisonous to a shocking degree, and refused to help us at all, indeed said the only flight they could possible offer would be three days later in business class at £7000 each, one way! In the end a terrific person at Delta helped us. But we will NEVER fly KLM again, and as a PR disaster being seriously unkind to people in dire trouble is SUCH a bad idea!

Avoid!!! canceled my holiday without notice. I spoke to them the day of traveling to check in, they say yeah it's fine just do it at the airport. I get to the airport to check in they have cancelled my flight no reason given, not even a refund. After a lot of back and forth agreed to refund me, said they refunded me and did not even refund me. Check the FB page read people story's. I was very lucky compared to some people.

First flight over 3 hours late, made me miss mu second flight. No communication I had to track down the staff.. put on another flight for the next day. That flight was a hour late making me miss my second flight again. took over 30 hours to get home. and Not one sorry or human interaction. Thank you American Airline for being available.

*** This flight was booked with Singapore airlines who, unfortunately used KLM for this leg. Even though they use the airline and gave me no choice - they refused to do anything to help and told us we had to sort with KLM - consider this if you're thinking of a long-haul flight with Singapore Airlines!!

Beware, even though we were well below our 70kg luggage allowance, KLM, unlike most other airlines, do not pool luggage. They insisted on putting two cases in my name and 1 in my husbands. It meant my husband was under but I was over - they did this to profit by $500 at our expense
for NO ACTUAL EXCESS BAGGAGE!! Singapore dud not charge us on the return journey because WE WERE NOT OVER OUR ALLOWANCE!
So, good news, the French travel ombudsman has ruled they should refund the fee- let's see how long the refund takes!
FRENCH OMBUDSMAN HAS FOUND IN OUR FAVOUR - STILL NO RESPONSE FROM KLM AND NO REFUND EVEN THOUGH THEY WERE INSTRUCTED TO SEND IT!!!
Still refusing to refund, ADR now looking into it too
KLM keep saying I was personally over my limit! I was travelling with my carer and we had a combined 70kgs, we had to take 3 medium suitcases so we could manage with the wheelchair. THEY messed up by allocating 2 cases to me and 1 to my husband, my carer. There was no excess baggage, just errors in how they were entered!
The ADR are currently reviewing the case now, let's see what they have to say.

took 4 flights with KLM within 4 days and 2/4 flights were delayed. the first flight delay caused me to miss the coach id booked and i had to take a £200 taxi - they are refusing to pay compensation and reimburse me for the this taxi journey. i am never flying with this useless company again

Staff don't know how to handle

I am utterly disappointed with my recent experience with KLM Royal Dutch Airlines. After requesting a refund for an inflight WiFi service that didn’t work on my inbound flight, I discovered—without any notification or confirmation—that my return flight was completely canceled.

How does a request to refund a non-functional inflight service result in the cancellation of a non-refundable ticket? This is not only baffling but feels intentionally misleading. The lack of transparency and communication is unacceptable.

To make matters worse, KLM’s app and customer service provided no clear explanation or assistance to resolve the issue. I am now stranded without a return ticket just days before my planned departure.
