> 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".
> 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.
