Easy Jet don't tend to release new routes until around Oct time for the following summer and indeed if they are continuing the route into April ?
Interestingly the fares for SOU - GVA all seem to be well under £ 40 each way for all days except school half term where the BOH - GVA fares are well over that price and have been since they were released .
Not sure if that is an indication of seats not selling well , lot more capacity this year of course with Flybe and Powdair to compete with
