Belfast International Airport has issued a warning to passengers to leave extra time to catch their flight during the G8 Summit.
The summit is being held in Northern Ireland on June 17 and 18.
The airport said there will be increased security and delays on all roads around the airport, in the days leading up to, and until the event.
"It is not possible to say how much extra time to allow for when catching a flight, but there will be heightened security on the roads round the airport and in the airport terminal itself," said spokeswoman Deborah Harris.
"Passengers leaving Belfast International, and indeed arriving, will see the increased security levels in the terminal as well as on the roads. but they should not be alarmed.
"We will be contacting travel agents, airlines and tour operators giving them advice so they can also pass this on to their clients, and indeed staff. It will take extra time to reach the airport and indeed to pass through the airport terminal itself.
"This is at the beginning of our summer season and we expect the airport to be very busy at the time of the summit."
Belfast International will be the airport used by all the official G8 delegations, but George Best Belfast City Airport is also expected to be very busy.
City Airport officials expect the Airport’s Heathrow services to be especially heavily booked with back-up teams to the official delegations.
