The trial will launch on 9 December on selected flights from Heathrow to Barbados and onwards to Antigua and Grenada.
Under the trial, passengers will be asked to take a free rapid Covid test at Collinson and Swissport’s pre-departure testing facility in Terminal 2 before being cleared to fly.
Virgin Atlantic said the trial was part of “an airline-led trial to gather vital data on the logistics and effectiveness of pre-departure testing”.
