My Lufthansa flight was cancelled, and subsequent flight was delayed, so the delay to Copenhagen was clearly subject to compensation. Although I am a frequent flyer, and well-acquainted with claiming compensation, my claim was refused after many weeks of waiting for reply from Lufthansa. I was very upset, and not willing to accept the decline. Luckily, I came across ClaimAir, and I submitted my story. The procedure was pretty simple, and the follow up on my case was most satisfying. The only thing that I had to learn was how to transfer the money to my bank account (I did use TranferWise, and I can recommend that one as well). The service provided thru the whole process, and help with transferring the money, was top-notch, rarely seen elsewhere regardless of business. This really is a company who cares about their customers, and they were so concerned that I got the money and that I was happy with everything. I never ever going to fight with an airline again, but rather leave it with ClaimAir. Their commission is so well-deserved.
