From their FAQ:

> How do I enforce my rights in case of a flight problem? To enforce your claims, it is advisable to seek professional assistance.

This makes me reluctant to trust them or their advice.

I'd expect an honest answer to be "you can totally do it yourself, but we will help you for X% commission".

Probably just there for legal reasons. They do mention their compensation on the site however.

> If successful, we transfer your money to you immediately. If the airline refunds your ticket within 7 days, our service is free of charge. After that, you only pay if we are successful (commission 14-28% plus VAT). For compensation claims, the commission is usually 20-30 % (plus VAT).

I think they know that just never happens.

If it's under 7 days it's probably because the airline is just less sketchy and it's super easy for them to get the money for you. The ones that take longer are probably the ones that are a bigger pain in the butt.
