Not sure if this is the right place to post. My husband is due back from Amsterdam on Friday and we have had to book a day 2 covid test to be able to complete the passenger locator form. He is there for work reasons.
He is only staying in the UK for a short while and will be returning to Amsterdam this Sunday, so less than 2 days later.
He won't be able to do the test as the results will come back after he has left and he will be getting a fit to fly covid test at the airport before he travels again anyway.
As the test will be unused, can we use the same test reference number for the passenger locator form when he returns to the UK for the second time?
