Jet2 has cancelled holidays and flights for thousands of customers.
The airline has now vowed to only fly to quarantine-free countries when it restarts flights and holidays from July 15.
The carrier told Mirror.co.uk that due to the "ongoing uncertainty caused by the coronavirus crisis" there would be less routes on sale and a lower frequency of flights for the summer .
The airline will not be operating flights and holidays to Jersey, Mykonos, Santorini, Kalamata, Halkidiki, Lesbos, Nice and Verona.
A spokesperson said: “We will be operating a revised programme for Summer 20, and we are looking forward to taking customers on our award-winning flights and package holidays.
“Because of the ongoing uncertainty caused by the coronavirus crisis, there is a reduction in the number of routes on sale and a lower frequency of services for Summer 20.
"We will not be operating flights and holidays to Jersey, Mykonos, Santorini, Kalamata, Halkidiki, Lesbos, Nice and Verona this summer, and there are some other reductions taking place across our nine UK bases.
"We are also in the process of making some changes to our schedules."
Jet2 said that customers affected by the changes would be offered a Refund Credit Note, a full cash refund, or the option to rebook with no admin fee.
They added: “We will be communicating details of our full Summer 20 programme very soon.
“We will only take customers to destinations that are quarantine-free, so we ask the Government to provide urgent clarity over air bridges so that customers can plan their holidays.”
