My questions are
1) if an existing operator such as AF/ KL / SN wanted to (effectively) divert some of their LHR or SOU services to BRS, maybe even to a destination they don't presently serve (say AF to Nice)
Not sure why AF would fly BRS-Nice when they dont fly LHR-Nice
AF/SN/KL serve the same destination from BRS as they do from LHR
