The Rennes service was launched last summer and will this year operate up to three times a week between June and September, starting 23 June.
Flights will operate on Mondays and Fridays through to 11 September, with additional Wednesday flights from 26 July to 30 August.
“Our focus is keeping Jersey connected, and we are excited to be providing direct links to France again this year with more flights added for greater choice and convenience as we look to sustainably build on last year’s programme," said Blue Islands chief executive Rob Veron.
