BA offers pretty good prices on its BRS-CDG-BRS services, such as 68GBP return if you depart BRS on a Saturday and arrive back into BRS on the Sunday.
I am surprised that nobody has mentioned GVA as a possible new Easy destination from BRS.
Let's hope that it is either AMS, CDG or GVA, and, whichever it is, that there is at least two daily rotations, thereby enabling a day return.
