I don't know when the site is up. But I expect that the site is up soon because "Big X-tra" is a new company with the very experienced Mr. Gunz (also with some negative experiences = FTI-airline and similiar) and needs to make their deals public.
The package is bookable directly in a travel agency. You can find more infos about bthe package in the travel agency or on sites like
