I don't understand your comment about Bournemouth was to lose Easy jet to Southampton "it will be curtains"?
Southampton are operating 3 times a week Geneva easy jet and from pricing enquiries this doesn't look a huge success at the moment.Even if this was a success,it doesn't mean Bournemouth would suffer unduly.Bournemouth will always offer Sun routes and further distance destinations,just because it has the runway capacity.
If Southampton was however to announce that they were to invest in the 450feet RW20 extension ( often mooted ,but nothing more),then I feel this could have a major effect on Bournemouth potential growth.
