@Escape-To-St-Ives0 The cancellation policy applying to reservations booked prior to March 14 is not connected to a country or locality's lockdown dates. It would be ludicrous to expect Airbnb to localize it at this point in the pandemic, when every country's rules change almost daily and lockdowns can vary even from one postcode to the next. There's no persuasive evidence that the UK's re-opening won't go as badly as those in the US, so I can't blame travelers who booked before the pandemic struck for recognizing now that whatever optimism they held onto over the last months was misplaced.
Airbnb is extending the cancellation window incrementally to reduce its outflow of cash, unfortunately at the expense of hosts, who would rather have more time to refill their calendars. We can expect that the next policy update will extend it to August 31, and so on.
