A new Loganair route between Dundee and George Best Belfast City airport started today (Friday).
It is the first direct air link between the Scottish city and Northern Ireland in eight years.
Twice-weekly flights will run over the winter on Fridays and Sundays to allow for weekend breaks.
Frequency will then rise to four flights a week from March 29.
The regional airline already flies from Belfast City to Aberdeen and Inverness, and recently launched a service to Glasgow.
Cormac O’Suilleabhain, head of UK brand partnerships at Tourism Ireland, said: “The return of this service is positive news for Scottish holidaymakers wishing to explore Belfast city and Northern Ireland.
“We have worked closely with Loganair for the past number of years and we look forward to co-operating with them again to maximise the promotion of their services to Northern Ireland.”
Dundee airport manager Derrick Lang said: “This is an important and welcome additional route that further enhances connectivity for the region.
“Travellers will be able to visit two of the UK’s most vibrant cities that have benefited from positive transformation in recent years.
“Dundee airport is a real asset for the local community and we are delighted to support this new service and wish it every success.”
The service operates to and from Belfast’s most conveniently located airport for the city centre.
