I'm waiting to see if Virgin Atlantic cancel my flights booked to LAX. I could claim a voucher now if I wanted to but if the flights end up cancelled I'd legally be entitled to a refund. I'm already battling with Virgin Atlantic trying to get a refund for flights they cancelled in early May for my trip to Florida / Disney World which was supposed to have taken place the last two weeks of May. When they cancelled the flights they said they'd automatically converted my flights to a voucher and so far they've been ignoring my requests for a refund. Apparently hardly anyone in the UK has been able to get a refund from Virgin Atlantic for cancelled flights unlike other airlines who have been honoring their statutory obligations to refund cancelled flights. I would possibly be OK with accepting a voucher for one of the two trips I had booked with them but not for both of them as I could do with at least some of the money refunded after we all had to accept a substantial pay cut at work because of the current situation.
