Looks like Aurigny are taking on the Birmingham and Exeter to Guernsey routes
Think you have your airlines mixed-up, the below is on the Blue Islands site this morning:
"BIRMINGHAM & EXETER - UPDATE
Further announcements relating to commencement of a new Blue Islands scheduled service to Birmingham and Exeter from both Guernsey and Jersey will be announced over the coming days. In the meantime, customers are assured of continued service to both of these destinations"
BI flew these routes yesterday as additional "rescue" flights initially.
