Blue Islands will fly from the Channel Islands to Luxembourg over four weeks to test demand.
Flights to Luxembourg will run on alternate weeks from 14 May to 11 June every Tuesday and Thursday, with a break during the May half term.
Jersey prices start at £289.99 one-way; they're £325.99 from Guernsey.
From Guernsey, the plane makes a stop in Jersey to pick up passengers before heading to Luxembourg.
Blue Islands CEO Rob Veron says it's good to add to the airline's route map:
“We are excited to announce a trial of direct flights to Luxembourg, and we thank our valued customers for the active engagement in supporting this trial.
With convenient departure times, significant savings on travel times and avoiding any airport changes or transit stays, our direct service enables the business traveller to maximise their valuable time away."
Blue Islands recently introduced a new route to the Isle of Man, also aimed at the business traveller.
