Aer Lingus regional partner Emerald Airlines will resume flights from Belfast to Cardiff Airport next month.
It will link the two capital cities five times weekly from 7 July.
Flights are now on sale and available to book at aerlingus.com.
Emerald Airlines opened its base at Belfast City earlier this year.
“Thanks to Emerald Airlines for restarting the critical connection between Cardiff and Belfast under the Aer Lingus banner,” said Marc Watkins, Aviation Development Manager at Cardiff Airport.
“It’s great that our customers looking to fly between Wales and Northern Ireland no longer have to travel via England..”
Ciarán Smith, Head of Commercial at Emerald Airlines said:” We are extremely pleased with the feedback we have received since beginning our operations from Belfast City Airport and believe Cardiff is a great new connection.”
