Of course, you can claim flight delay compensation on your own, but it is better to claim for flight delay compensation using claim company service, because airlines usually reject and may reject the flight delay claim, which was prepared by their passenger on his/her own. In fact Flight Claim Companies have more experience in claiming process and most of them charge about 25% in case compensation is received (such as, AirHelp, Skycop, Flightright etc.). And most of them work in the way “No Win, No Fee”. You will find a relevant claim company in Best Companies.
