I’ve tested positive on a lateral flow, well several tests, some positive, some negative, so have taken a PCR today but won’t get result till tomorrow earliest. Have bought my ticket, praying it’s negative but thinking it’s unlikely which I’m gutted about. How would I transfer this ticket if I can’t go? It would go to a extremely high capper who didn’t keep the semi ticket earlier in the year, so I have no issues on that front. Cheers.
