Five months of silence and an ignored GDPR request — case PAT3516626
Assignment of claim signed 15 March 2026. Flight W43872, Wizz Air Malta, four passengers. Case reference: PAT3516626.
Since then: no substantive update on the case. No confirmation of whether the airline was ever contacted, no copy of any correspondence, no indication of the stage the file is at.
When I attempted to submit a claim to the airline myself, I was told a claim already exists on this flight — filed by Claim Flights. So the claim is with them, I cannot pursue it, and I am told nothing about it.
None of this needs to happen. One informative email would resolve it, and I will update this review the moment I receive one.
Great experience of cooperation with Claim Flights
Great experience of cooperation with the company Claim Flights . My flight was canceled 2 hours before departure and six months later I received compensation. My manager Agnieszka was very kind, answered all questions and helped to figure everything out. If your flight was canceled and you want to get compensation, I recommend you Claim Flights 🤝
For the compensation process for the flight cancellation, I was assisted by Agnieszka Fanslau. She was helpful and quick to respond to my various requests. I had a great experience.
My questions were always promptly and professionally answered in an extremely timely manner. And, the money was deposited into my account; a seamless transaction!
Shady- you won't receive all your money after 7 month wait
Took 6 months, Agnieszka Fanslau was impolite and said "ok go file a complaint then" instead of providing a proper resolution. They do NOT provide documentation of how much they receive. It's quite suspicious and they give horrendous exchange rates so you lose an additional 5%. So in the end you lose much more of your money. They will not provide any proof of how much they actually receive from the airline. Very shady business

Kimberly. I understand your anger.
The internet exchange rate showed you $523 but you only received $501,86 (you wrote "25% fees would be 450 euros. 450 euros is $523 but I only received $500"). The reason is that on your request we have paid you with paypal and paypal made their normal exchange rate which is less than the inter banking rate. We even paid over the paypal "friends and family" function and covered the 3,99 Euro paypal fee on our expense.
Just to remind you that you have called us an idiot "You’re an idiot" and were harsh with us.
Anyhow we are glad that you have received $501,86 from your flight delay case. Please check out what you would have received on other major flight companies https://claimflights.com/flight-delay/compensation/claim-companies/
We will send you the bank and transfer statement from paypal to your email adress to proof the exchange rate and that we have covered the transfer cost on our expense. We would appreciate if you would re-evaluate the review after reviewing the statements.
My experience with this company was wonderful! My consultant, Ms Fanslau, was very helpful and responded quickly to any of my questions. She made the whole process of getting compensation for my canceled flight very easy. I would highly recommend this company!
Agnieszka Fanslau from Claim Flights was really helpful and supportive of our case. There was great communication with Agnieszka and she managed to offer us the compensation within the time frame that was specified. We are very happy with the result and would recommend these services to anyone entitled to flight compensation.
Communication over email was great and they managed to get the compensation I was owed from Swiss Air after they had denied me multiple times. Thanks Claim Flights and Agnieszka!
I am pretty impressed with the result. The process seem a bit opaque, the only way to know about the process is emailing the person assigned, and still, they wont provider much info, but as soon as there some news, they Will wirte you back.
In general i am very happy with the service and the supoort provided by Agnieszka. They helped me to claim a compensation for a flight that happened 3 years ago and Iberia was refusing to compensate.
Thank you so much!
We had a flight cancelled, which was very inconvenient as we missed some important appointments. Therefore, getting a very fair financial compensation, made possible by Agnieszka, eased the pain, so to speak.
In my case the whole process lasted more than 2 years, because as I've been informed, the airline wasn't agree with the compensation and it was necessary to go on court, the process being transfered to a local lawyer.
In this time, I was periodical informed about case status by Ms.Agnieszka Fanslau
and Mr. Kunicki, which were very professional, helpful and responsive.
In the end I received the compensation I wasn't even expecting.
Highly recommend Claim Flights service!
Hello,
Please note that I am totally dissapointed about the way one of your agents, Mrs Agnieszka Fanslau, is treating the customers, as they are totally stupid.
Find bellow an e-mail that I received from her:

PLEASE READ CAREFULLY (READ WORD BY WORD AND THINK WHAT EACH WORD MEANS). AFTER YOU'VE READ IT, ASK SOMEONE WHAT THE MESSAGE FROM WIZZ AIR MEANS. PLEASE ASK SOMEONE WHO CAN READ FOR HELP:
I would like to inform you that a claim for the same customer, booking and flight has been received from another company and compensation in accordance with Regulation 261/2004 has already been paid to them.
There is absolutely no indication anywhere that YOU received compensation.
THERE IS NO INFORMATION THAT YOU RECEIVED A COMPENSATION. THEY NEVER WROTE ANYWHERE THAT A COMPENSATION WAS SENT TO YOU.
Best regards

Our contact person was really nice and accomodated our request. We were reimbursed for the cancelled flight because of their help. We didn't expect to work, but they managed well. Thanks, Agnieszka!
All was clear and transparent. I gave them all the info and let them handle it. It took some time (but that is to be expected of course) and all of a sudden, I got an e-mail they received the money for my claim. It was deposited to my account some weeks later! I am absolutely very happy with the service. I tried to handle the claim by myself first, but it just isn't possible to do it by yourself. Thank you Claim Flights for the help!
