Biarritz and Toulon were both routes flown from from BOH in S15, so it seems BEE consider they are worth operating again. Bastia was flown from SOU last year.
Although I'm sure it would have been preferable to (re-)launch these a bit earlier, the S16 offer from SOU is now looking quite good, and on some routes (eg, BOD, LRH, EGC) has the most capacity they have ever offered (
AFAIK).
