EC Regulations 261/2004 I made a claim under this ruling with thomsons and was successful, both myself and partner received the equilivant of 600 euros each.
However it was back in 2010 and was delayed for 26 hours from Mexico.
Im not sure how far you have got, but we got Dme D Hutton who was chair of the CAA at the time involved, we had first written to Airport Users Council as well, who at that time wrote to thomsons to advise that they should fulfil their obligations, but that got a no go, and it was at this time that we got the CAA involved who can fine them.
There were talks before we got our cheque as to another hearing back in the ECJ to appeal but nit sure of outcome.
Perhaps contact CAA and ask for their clarification.
Pm me if you need any other info
