I was about to post the exact same question. WE flew Air France from SFO to Ljubljana through Paris and were delayed about 7 hours due to 380 not leaving on time. Flight was delayed with about 36 hours warning.
We are 4 passengers and I believe we are entitled to 600 Euros * 4. I have the boarding passes.
Same question as JakubH. Should we try to apply ourselves for compensation? Or use a service like instalocate or goclaiming? goclaiming.com takes 25% commission (!!!!). I can't find anything out about these companies either and agree they seem dodgy.
Any advice appreciated!!
