The FCO has announced that it is advising Brits against all but essential travel 'indefinitely' amidst the coronavirus. The original advice was announced on Tuesday 17th March and initially applied for 30 days.
However the FCO is now extending this to 'indefinitely' as the global pandemic continues. This means that if you have a holiday booked, it's now effectively cancelled.
It's likely that your travel firm or airline will get in touch to discuss your options - this may include rebooking your trip for a later date.
A lot of travel firms have also been offering vouchers and credit. However if you want your money back, you are entitled to request a refund.
