I've received notification from Flybe that my LYS-SEN flight in mid-May will be operated by Jota. I've also received confirmation that my outbound flight a week earlier will be operated by Flybe, as will my SEN-VIE-SEN flights in June.
It seems to me that Jota will provide one aircraft for the first few months with Flybe providing either an EMB175 or 195 as the second aircraft needed to operate the schedules for the 11 routes. Presumably both these aircraft will be replaced by the EMB195s that Stobart say they will be adding to their AOC.
