For anyone that is interested, in tonight's JEP (24th July) there is a Flybe. supplement that states that talks are on-going with regards to the new Paris CDG route, however, Flybe. is optimistic that flights will begin in October with an announcement expected within the next few weeks. The flights will be from Jersey and Guernsey, 1x Daily, 6x Weekly. Further southern routes were hinted at as well for the future.
Looking at the Flybe. timetable my reckoning is that the service will be flown with the Guernsey based DH4. The winter timetable shows that the mid-morning Southampton flight switches from the GCI based Dash to an SOU based one, hence freeing up a period of 6 hours when the aircraft is free to fly to CDG.
All good news!
