Hi vladman!

Your chances for compensation are excellent from my point of view. However, most airlines will try to refuse compensation, forcing you into a long legal battle with them with an uncertain outcome. For this reason you may decide to make use of the services of:

http://www.fairplane.de (if you know German)

These are legal consult companies that will fight for your claim. You will only have to pay them if your claim is successfull. Check their websites for the details.
