EASYJET is to resume some flights, including Belfast routes, from June 15 with all passengers and cabin crew to wear face masks to protect against coronavirus.
The low-cost carrier announced that its initial schedule will involve mainly domestic flights in the UK, where there is enough customer demand.
Further routes will be confirmed "over the coming weeks" as coronavirus lockdown measures across Europe are relaxed.
EasyJet will initially fly out of Belfast International Airport, Gatwick, Bristol, Birmingham, Liverpool and Edinburgh.
The only international route will be between Gatwick and Nice in France.
Graham Keddie, managing director of Belfast International Airport, said it was a "welcome and reassuring sign" to see the flights resume.
"We will be ready to accommodate these flights and our teams have been working round the clock to ensure that all measures will be in place to ensure the safety and well-being of all those who pass through the airport," he said.
When flights restart, no food will be available on board and customers will have hand sanitiser and disinfectant wipes provided.
Passengers and crew will also be required to wear masks in airports and on aircraft.
EasyJet said its planes would be subject to "enhanced cleaning and disinfection".
Chief executive Johan Lundgren said: "These are small and carefully planned steps that we are taking to gradually resume operations.
"We will continue to closely monitor the situation across Europe so that, when more restrictions are lifted, the schedule will continue to build over time to match demand, while also ensuring we are operating efficiently and on routes that our customers want.
"The safety and wellbeing of our customers remains our highest priority, which is why we are implementing a number of measures to enhance safety at each part of the journey, from disinfecting the aircraft to requiring customers and crew to wear masks.
"These measures will remain in place for as long as is needed to ensure customers and crew are able to fly safely as the world continues to recover from the impact of the coronavirus pandemic."
A number of other airlines have announced tentative plans to ramp up their operations from the skeleton schedules currently in place due to the coronavirus pandemic.
Ryanair plans to restore 40 per cent of its flights from July 1, while British Airways is also due to make a "meaningful return" to service next month.
