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."

Issuing further guidance to agents on next steps, Jet2 said client bookings would be processed automatically with a Jet2holidays refund credit note given for the full price of the affected holiday.

Credit notes will be emailed shortly for impacted bookings and Jet2holidays will issue each credit note with a unique code to be passed to the lead passenger on the booking - valid for redemption until 31 July 2020.

“This can only be redeemed through the travel agent who originally made the booking. The original booking will be cancelled at 100% loss, this means you will retain the commission you have earned on the original booking,” Jet2 said.

“Please book the new holiday on the trade website and complete the relevant online form which will be included in the email with your customers refund credit note and on our social media channels Partners2Success.

“Once you have completed this process you don’t need to do anything else. The trade team will apply the refund credit note to the new booking for you and a new confirmation will be issued.”
