AirHelp is your flight lawyer as a service. They file on your behalf and fight for you in court to make sure you are properly compensated for your delayed or changed flight. Every year, 99.9% of all flight change compensations are not properly claimed due to poor claim knowledge and the amount of time filing takes. Flyers are eligible for up to 400% of their ticket purchase price. AirHelp only charges 25% of the compensation when they win, thus requiring no upfront cash from their customers.
