Blue Islands flights between Jersey and Dublin will start on Thursday 19 May after post-Brexit licencing issues were resolved.
The service was due to begin in late March, but the licencing problem stopped that from happening.
Affected passengers were put onto flights to Belfast City Airport instead and transferred to Dublin by coach.
The airline's Jersey to Dublin route has been approved by the Irish Department for Transport.
"We are excited to be able to fully launch our Jersey - Dublin service and would like to thank all our customers for their understanding and patience while the licensing issues were resolved.
Thanks to the Channel Islands, Irish and UK governments working to ensure the route is able to operate, we look forward to providing Jersey residents, and visitors to our island, our Dublin service this summer.
We are proud to play our role in sustainably developing Jersey’s connectivity and eagerly anticipate a busy summer building our regional route network, and of course welcoming many visitors to discover Jersey." - Rob Veron, Blue Islands CEO.
