Recommend, but takes time...
I recommend flightright especially for claims with low cost airlines like Ryanair. They take time... Patience needed, my case took 6 months. But flightright kept me updated regularly and they were very professional. My flight was delayed 36 hours and they managed to help me get 200 euros. Not much considering Ryanair owed me at least 400€ for more than 24 hour delay but still thank you!
