Rhino sorry i was trying to say that all airlines come out with the crew costs and efficiencies not just your mob. The problem (from experience) is if you go light on crews then a fixed roster can grind the airline to a halt whereas a flexible one can keep it going for a little longer. The efficiency maybe for example moving towards a Ryanair type pattern (noting whipsnaps comments).
I'm sure the "consultants" will come up with something novel.
My own personal opinion is EZY have created the problem themselves, target and bonus driven rather than focusing on maintaining crew numbers. Now they are in a hole they are back tracking on their FRMS principles (although they have created a monster) and all they have learned. Moving to random rosters isn't the answer for sure....
