Jet2.com and Jet2holidays have announced plans to restart operations from 1 July.
The revised date comes slightly after its original target to recommence flights and holidays from 17 June.
A spokesperson said ongoing travel restrictions amid the Covid-19 pandemic had led to the date being pushed back.
“The health and safety of our customers and colleagues is our absolute priority, and we are continuing to monitor the situation very closely,” the spokesperson said.
Addressing the trade, Jet2 said its commitment to working in partnership with independent travel agents "has never been stronger” explaining how it would be contacting agents with “a number of options for customers” including rebook options, rebook codes and flexible terms and conditions.
"All of these super flexible options are designed to help agents look after their customers, and we are very proud of the feedback we have received so far. We can assure all agents affected by today’s announcement that they will receive the same level of service," a spokesperson added.
"We have said throughout that the sun will shine again and when it does, we will be there to take customers away on their well-deserved holidays. As well as this, agents can be assured that we will be implementing measures, in consultation with the relevant authorities, to ensure the safety and wellbeing of everybody onboard. We will announce further details on this in due course."
