The flights start in July and will run four times a week from the Channel Island to the French capital. This latest Guernsey service follows a new service to Dublin which is due to start in June.
Mike Rutter, chief commercial officer at Flybe, said: "With this brand new route to Paris we're giving Guernsey travellers an unbeatable low cost offer for direct travel to the French capital. With the recent addition of the Guernsey to Dublin route we remain resolutely committed to giving our customers an exciting and convenient range of travel options."
Elsewhere, the airline's three new routes from Inverness started service today. Daily flights to Exeter, Manchester and Southampton were launched from the Scottish city as part of Flybe's summer schedule.
Commenting on these new flights, Mr Rutter said: "People are advised to book now to ensure the best possible fares on what – according to ticket sales – are already proving to be highly popular routes."
