From my personal point of view I have been waiting for easyJet to cancel them so I will be quite glad when they do. I have flights booked for early April but I have no intention of going then. I'm not worried about catching COVID myself, since I will have had my second vaccination 3 weeks before I am due to fly, but the restrictions are still such in the UK that there would be no point in going at that time. I could just change the booking to later in the year but, when I did that previously, somehow I managed to lose my pre-paid over-wing seats and had to pay again. I would prefer to get a voucher and use that to book new flights from scratch. I am not bothered about getting a cash refund as I will fly at some time within the next year so a voucher is fine.
