Jet2 said they will restart their flights and holidays in June in a statement released today.
The airline and package holiday company revealed that they would be restarting flights on June 17.
But anyone with holidays or flights booked before then has had their booking cancelled - reports Belfast Live.
The statement said: "Due to the ongoing uncertainty caused by the coronavirus (COVID-19) pandemic, we’ve decided to recommence our flights programme on 17 June 2020.
"If you're travelling before this date, unfortunately, your booking will be affected as our flights won't be operating.
"We're contacting all affected customers about their options, including how to amend bookings to a later date, so if you were due to travel before 17 June 2020, we'll be in touch.
"We know just how much a well-deserved getaway means to you and how much it gives you something to look forward to, particularly during difficult times such as these.
"We’re continuing to operate a fully-staffed call centre but the number of calls we’re currently receiving is unprecedented and more than we can handle.
"Therefore, we’re proactively contacting all affected customers in departure date order, which we think is the fairest way. Please be patient with us as we do this and remember that we’ll get in touch with you."
The company added: "Although these are difficult times for everyone, the sun will come out again. When it does, our award-winning teams will take their customers on holiday - a well deserved package holiday they can trust - once again."
