A tourism body has called for the NI Executive to ease travel restrictions between NI and Great Britain.
Currently under Covid guidelines, people should not travel in or out of NI unless it is for an essential purpose.
In March Stormont agreed a phased plan for taking the country out of lockdown and the return of leisure travel falls under step five.
The Northern Ireland Tourism Alliance (NITA), which represents tourism operators, visitor attractions and tour guides said the travel sector is facing a set back of up to 15 years.
Joanne Stuart, Chief Executive of NITA told Good Morning Ulster on Tuesday that said businesses have been left without much hope due to a lack of dates from the Executive.
She said: "Anybody coming from Great Britain to Northern Ireland and who is staying for more than 24 hours has to self isolate for 10 days.
"At the moment we are more or less closed so unless you are travelling for an essential reason you can't come to Northern Ireland.
"That GB market is going to be really important for us this summer.
"With the testing and the roll out of the vaccination programme and the protocols, airlines and ferries have put in place, we are getting to the point where we should be able to open travel up throughout the UK.
"The problem is we really don't have a plan. We want to see the roadmap for international travel, but for us we also want the roadmap for UK travel."
On Monday, Boris Johnston revealed that the UK government confirmed a traffic light system for when international travel returns, but the NI Executive have to decide if they will follow.
Graham Keddie, Managing Director at Belfast International Airport explained the importance of being given dates and wants NI to follow England.
"To get summer re-started aviation needs it [traffic light system], hospitality needs it, travel needs it and we need to get going again.
"The damage to businesses across aviation and hospitality has been huge. We need some relaxation at some stage. With England, Scotland and Wales opening up, we need some dates.
"The businesses across this airport have been damaged, including the airport itself. We are on timed clocks. There is only so much longer we can survive as an industry," he said.
