Ted, if you looked at the larger quote rather than take a few words out of context, you can see the Innova antigen test Is being used at Heathrow Airport, if not system wide for Virgin Airlines.

"Virgin Atlantic customers flying to Barbados or onwards to Antigua and Grenada on selected flights will now receive a free test at London Heathrow Airport as part of a trial to gather data on the logistics and effectiveness of pre-departure testing. This also adds confidence for passengers in being assured that anyone traveling is Covid-free. 
The test being used is a rapid lateral flow antigen test, which delivers results in 30 minutes and is the same test used in Liverpool's mass trials. ""
