Back in August, we used Wren Healthcare (Power Road) Antigen tests for flying to Italy (yes - even back then Antigen / Lateral Flow tests were sufficient for Italian requirements).They proved to be very efficient and both my wife and I had our (negative, fortunately...) test results through via text in less than 15 minutes.They were also comparatively cheap / cost-effective when compared to most pharmacies.By the way, you cannot use NHS issued tests to prove that you are 'Fit-to-fly' (I believe that this applies to pretty much any country) - you must use a 3rd party supplier approved by your carrier.
