KLM Reviews 8,358

Customer service London number, yesterday over an hour so hung up.
Same today.
Really poor customer service if you want to speak with a human.

I am amazed at the bad reviews here.I fly KLM every chance I get because they've always been good. I had one single flight cancelled and I submitted my compensation claim. It was paid within 2 weeks, no questions asked. The service is great, reliable and the app and IT work well.

I always, always choose KLM because even if it goes wrong they got yah covered.

I would have given them zero stars if possible. They damaged my luggage on a trip to UK. Filled a claim over a month ago with absolutely no response

The KLM app is very frustrating to use and provides a poor user experience. It feels outdated and unintuitive. I would strongly recommend looking at what SAS or Norwegian are doing with their apps, as they offer a much smoother and more user-friendly experience.

Please prioritise improving the app. The experience is so poor that I would choose another airline if possible — and unfortunately, this has not improved over the past several years

This is the first airline that sells you a continental flight with out including a checked in luggage

Wish I can give less than 1 star.

I had a broken entertainment system on a long haul flight from Amsterdam to Delhi.

Smooth boarding and well-organized flights.

This is very worst airline and customer service is very terrible , one of the bad airline in my life . My Banglore to Amsterdam trip was cancelled because of staff bad behaviour

Absolutely disgraceful that a company in this day and age believes it is acceptable to treat paying customers in this way!!!
A missing piece of luggage that no one appears or seems to care about it's location
We have spent the past 5 days on the phone, emailing and back at the airport, and out of the tens of people across the globe, not one person can find any trace of the suitcase
Nobody answers their phones, the website help may as well be taken down because it is of absolutely no use to anyone and not fit for purpose

By the way, this was a business class flight

Terrible...... Avoid at all costs

My flight was cancelled, and I got a another one with result of much longer time in a airport than expected.
They were nice to write to me in the app that I could redeem a voucher for food and drink.
Unfortunately, since the app is, supposedly, developed by non educated people with bad skills for software development, it was not possible to redeem it in the app. It was poorly explained where exaclt to download the voucher.
I tried to contact the support, but it was also very difficult.
they write 24/7 support on their website but that is definitely not true. I contacted by multiple ways, but I didn't got any answers even after 18 hours.
This was so horrible.
I finally found a person in the airport that could help me in some way, but it was slow, and the employment spend multiple minutes by laughing while I was in a hurry to get something to eat before my gate will open.

This makes me so stressful and angry so my energy became very low to proceed further.
Completely horrible service because it seems like they can make educated people do their work. I'm not even sure that their pilots have an education

I have never had a poor customer service experience from any company in my life as i have had from KLM.

Their customer service is shocking and there is no way to get a resolution as everything is done on their portal.

I am outstanding compensation/reinbursment for cancelled flights and lost baggage for over 8 weeks without any payment or proper contact.

The mark of a good company is when things go wrong and are rectified quickly. The opposite happens with KLM.

I can say honesty that I will never travel with them again.

Worst flight ever. Everyone was freezing. They turned on the air conditionner to the maximum for 12 hours. I wouldn’t reccomend this company to anyone

Booked a flight from ams to Rome in early January which was cancelled 3 consecutive times. Held my luggage even when I told them I was getting a train out of the country and would not be getting on a flight. Ever since then I have not been able to get any documentation or reimbursement in relation to the bag even though they had it for 15 days. Could not even get a document to give to my travel insurance to cover the costs. Worst customer service I have ever received.

Klm service was great. They provided free rebooking for a cancelled flight and also issued a full refund. They were really understanding and nice.

Overcharged for pre-booked seats. Customer Service told us they couldn't do anything to refund us until after our flights in December/January. Now unable to claim as flight taken and previous 'Ticket' for issue doesn't exist anymore.

Generally speaking fine as an airline, but the business practices are bullshit; example is the "keep silver" option. So I need to feel honored for spending money on something I already own? Ridiculous to say the least.

Our journey was affected by the snowstorm that hit Amsterdam in the first and second week of January 2026.

Communication from KLM was sporadic and unclear at best.

Our main complaint is with the claims process, where we were reimbursed approx. 700DKK due extra expenses incurred of about 4500DKK.

We are currently challenging the decision.

KLM lost my luggage and closed the ticket. The KLM agent is saying that I am basically screwed if my luggage is lost.

Flew from Glasgow to Amsterdam on Friday 2 January albeit almost 4 hours delayed. Due to fly back Monday 5 January,flight cancelled by email the night before. Then received another email saying flight now Wednesday 7 January Amsterdam to London city then BA flight to Glasgow an hour after arrival. That was also cancelled. Couldn’t get anyone by phone or any other method. On the Thursday the 8th January opted for a ferry from ijmouden Amsterdam to Newcastle over 16 hours.Had to get someone to drive down and pick us up. Several people on the ferry same thing, abandoned by KLM. Still waiting on any form of compensation and out of pocket hundreds of pounds, very disappointing to say the least, in my 70s and was a very traumatic time.Also never heard anything from KLM till 14 January assuming we had got home

Flying KLM is definitely better than most American Airlines. The staff seem to genuinely care about their passengers. In-flight experience was great, as was check-in. Their website functions, but is a bit clunky. I do wish that they'd not stoop to having you pay for seats and the like. It really is bottom-barrel capitalism. How about one ticket price that includes standard, expected features? You know - a meal, your carry-on, selecting your seat. nothing extraordinary here. The people made the difference here over US carriers.
