AMS can be a quiet route on Tue, Wed, Thur, hence why EZY is only doing a double on Mon, Fri, Sun which are the most popular days of the week. It will take time before WW manages to get decent loads, however i can remember when tickets first went on sale from BHD to their new routes it was working out a hell of a lot cheaper to fly from BFS... if the prices still have the same difference then that's probably why.
