KLM Avis 

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.

DO NOT USE THE UPGRADE FUNCTION. I used upgrade as a once in a lifetime option to move from economy to business class flying to Peru. They upgraded one way and just to premium on the way back. However the charge was the full cost of business class. I made a complaint that they ignored and closed after 5 months with no contact. I know that sounds like a minor thing but the cost was huge for once in a lifetime. So disappointed. Just wish I had this review before I used the function

Horrible customer service. No help at all. Impossible to get in contact with airline by phone.

There should be a plunger emoji to represent KLM, the absolute worst airline ever, customer service is non existent, stayed on hold for 50 minutes to be told by a recording hold time would be 2 hours then it hung up on me. Lost my bag, rerouted my itinerary without telling me, booked me on a flight I didn't agree too, and on and on, If you want to fly shit show air book a ticket on KLM, and as a Delta Medallion member, Delta you need to cut them off as a partner they are making you look terrible.

How do you contact customer service? Absolutely dreadful website designed to discourage contact. Phone numbers non-existent. Will not use this airline again!

Flight cancelled on 2nd January from Schipol to Leeds Bradford by KLM. Me and My Wife spent 4 days in Amsterdam attempting to get home , eventually got home with Eurostar via Kings Cross.At no Time did we get to see any KLM staff and had to Fund 4 days in hotels plus buying clothes as our Luggage was sent to Leeds on a plane not available to ourselves!The cost ran to £2500 inc the train. Klm have informed us there is no compensation as it is weather related even though there were flights to Leeds on the following days. The treatment we received from KLM is disgraceful. Take my advice to never ever use them . KLM CEO sent email apology stating that we will be compensated totally false.

If i could give less than 1 star then i would. All I want to do is give them money for tickets to fly my children to the UK as unaccompanied minors
Website keeps giving errors all week, no agents available on the phone. What a waste of time this company is. If I had alternatives I wouldnt give them a penny more

Dear KLM, when I pre-select and pre- pay for a seat to India and checked in for my flight - I do not expect to wake up the day of the flight to a changed seat without any notification, explanation or the offer of a refund. I am a KLM Gold member, meaning I fly a lot with this airline.
Never in all my years of flying have I had this happen to me. The customer service agent could not help me, neither the ground stuff. Just “tough luck”, please request a refund. This is really poor service and not appreciated

The food and drink was very poor as was the service
Plus our baggage arrived a day late

Very difficult to navigate website.
Not all fees included in the total. They gave me a booking reference for flights i was looking at without actually meaning to book. When I booked a flight seats and bags had to be included but then they asked me to choose and seats came at a price. Also I have received an email confirming payment but their website said my booking isn't finalized. Of course it was after their helpdesk is open and the website said the ticket price is only locked till 3 hours later. No 24hour support. Trying to get them on the phone but I now have very low expectations. Let's see if they can surprise me positively.

I recently flew with klm to japan and although it was a good flight the service was terrible i upgraded my seat to luxury seats and was impressed untill the menu was handed to me both going and returning from japan it was mistly fish or no choice i explained on both trips i did not eat fish and was there something else i could get instead and was told no thats it so either i eat the fish or dont eat its not their problem their is no on board service where you can even buy food so i went without a meal even though i payed exyra upgrade seat also on eveey other airline when you ask for a coke you are given the full can on klm you are given a shot glass with coke thats it and i have flown on many airlines around the world so it feels other airlines make you feel welcome for flting with them but klm want you to thank them for letting you fly with them as your requests or comfort dont matter if you eat or dont up to you you get what we serve thats it and its a very long flight with just a small bun and a bit of friut and flight crew are uncaring to your need as its not their problem aa i siad eat or not your choice but thats all you get tough luck

Recently flew with KLM to Cape Town. All 4 flights were delayed. The flight was literally freezing. Food not great. Arm of my seat was broke outbound and headrest broke on the return. And our luggage didn't arrive. The real issues have been since we returned and tried to claim our expenses. It is practically impossible to contact Customer Services. Our online claim has dragged on, they said they have emailed for further information but I've never received any emails. Waited 50 minutes before someone answered the phone, they tried to resend the emails while I was on the phone to them and they still haven't been received. They keep asking for the same information, despite the information already being submitted. Feels like stalling tactics. I can't believe how far KLM have fallen. I would have to give serious consideration to use them again. They have lost my luggage before in 2019 and the reimbursement process was not nearly as laborious as it is now. If I could give them Zero I would.

Absolutely awful customer service. Said that I would receive a telephone call from their customer care department, however no call came. Called them again and the agent was so rude. Constantly cutting me off and interrupting me, not letting me finish what I was saying.
0/10. Completely abhorrent company. Absolutely useless.

This one star is 2 stars too much!! The level of ignorance and diabolical customer service is an absolute joke!

I have been trying constantly to re book my flight. No one is helping me, they have said I can't re book online. I am close to my flight departure on February 2nd. I have been trying for weeks now to change my booking and nothing. They are apalling.

Flew with klm this week for 1st time, I have to say if im ever planning on going to Amsterdam ill definitely be booking klm, staff were amazing, so attentive, also food n drink are complimentary on their flights, we were offered cheese crisps,sandwich, wine, beer or soft drink ( one each) for the flight

Flew out from Glasgow 2 Jan return flight 5 Jan. Cancelled due to weather rescheduled 7 Jan this time Ams to London city then BA flight to Glasgow, cancelled eventually took ferry to Newcastle then made my way to Glasgow. Loads of people on ferry stranded since Mon. Not a penny from KLM. Not asking for flight reimbursement but my hotel bill £400 plus food etc, Shocking treatment from the so called airline.UPDATE after battling with klm I have had compensation £30. Total joke if I could give a minus 10 I would. Given up now and accepted being out of pocket for hundreds

Many many thanks to your Ground staff LHR T4 1c 9:30 departure and 10am flight crew.
You treated my fiancée and I superbly, especially with last minute request.

Trying to get a refund for flights which were cancelled /disrupted by the bad weather in January. Website is hopeless, chat lines not available. When you call the UK ‘Customer Care” you end up in the Phillipines. Agents can only deal with general issues. There seems to be a lack of information between departments, so you can never speak to someone who can really help. They do not respond to emails. You can only complain online, which is impossible if you have already a claim.
