I was stuck in Vienna airport for more than 5 hours after NIKI Air cancelled my flight to Milan. I got a flight later that day but lost one whole day of my time. The ClaimAir team took on my case and finally got 187 Euros compensation for me without me having to do anything except provide them the facts. ClaimAir handled the whole process with professionality and efficiency keeping me updated of progress at each stage of their negotiation with NIKI Air. Finally I received my compensation through PayPal. I would thoroughly recommend ClaimAir to anybody who feels they have been short-changed by any airline and who rightly deserves to be compensated for lack of service.
