Virgin Atlantic says it is trebling the number of seats on its seasonal Belfast to Orlando route.
The airline flies direct from Belfast International Airport to Florida, from March to September.
Next summer, it will fly out of Northern Ireland on Mondays, running from March 26 to September 4.
And it's also adding additional flights on Friday during June and July.
Uel Hoey, business development director at Belfast International Airport, said:
“We are thrilled to announce this extensive growth in Virgin’s Florida programme from Belfast for Summer 2018, the only direct flights offering the iconic Virgin product from the island of Ireland.
“We are also pleased that Virgin, in partnership with Delta, have grasped the clear opportunity to capitalise upon the strong established family market from Northern Ireland to Florida recently abandoned by United Airlines.
“We are confident that good value in the exchange rate and the convenience and uncongested experience of using Belfast International Airport as a departure point will prove increasingly popular next year for passengers right across the north of the island of Ireland.”
And Richard Myerscough, senior vice president of sales and distribution at Virgin Atlantic, said: “Since launching our first flight from Northern Ireland two years ago our services have gone from strength to strength — so I’m really pleased to announce that 2018 will be our biggest ever season from Belfast International Airport.
"We’ve always received a really warmwelcome from Northern Ireland, and the additional flights will allow even more customers to fly direct to the sunshine state with Virgin Atlantic.”
