American Airlines, British Airways and oneworld have launched an optional Covid-19 medical-based testing trial on selected flights from the United States to London Heathrow.

The programme is an effort to scientifically demonstrate how Covid-19 testing can reopen international travel and remove the need for passengers to quarantine on arrival.

Rival United Airlines is currently trialling a similar scheme on its transatlantic route.

The free oneworld tests will initially be offered to eligible customers booked on American Airlines flight AA50 departing Dallas/Fort Worth (DFW) to Heathrow; British Airways flight BA114 departing New York’s John F. Kennedy Airport (JFK) to Heathrow; and British Airways flight BA268 from Los Angeles (LAX) to Heathrow, beginning November 25th.

The test will be expanded to American Airlines flight AA106 from JFK to Heathrow, with a launch date to be communicated.

Eligible customers booked on flights that are part of the trial will be contacted by American Airlines and British Airways with instructions on how to volunteer.

Each customer participating in the trial will take three tests in conjunction with the journey.

If a customer tests positive, they should reschedule or cancel their travel.

The first test, to be taken 72 hours before departure from the United States, is a convenient at-home RT-PCR test provided by LetsGetChecked.

Customers will self-collect a nasal sample, under the supervision of medical professionals via a virtual visit.

After landing at Heathrow, participating customers will proceed to their second test at the airport.

The LAMP test, provided by Collinson, involves the collection of a nasal sample by a medical professional.

After the test is completed, a test kit for the third test will be provided to the customer.

The test kit offers an at-home testing option, through the self-collection of a saliva sample which is taken three days after arrival into the United Kingdom.

American Airlines chief executive, Doug Parker, said: “American has already successfully introduced a pre-flight Covid-19 testing programme for customers travelling from the US to international destinations across the Caribbean and Latin America.

“We have received tremendous feedback from our customers in response to testing, as it provides peace of mind for safe and enjoyable travel.

“The UK is a critically important business and leisure destination that our customers want to visit.

“We believe the results provided by this trial will be vital for reopening transatlantic travel safely.”

Trade between the UK and US totals more than £200 billion (US$ 262 billion) a year, which airlines are critical to facilitating.

Prior to the Covid-19 pandemic, together American Airlines and British Airways flew to more than 30 destinations in the US from London.

Today, the carriers are flying a fraction of that figure.

Previously, the carriers operated up to 111 flights a week from London to New York; now they operate 14 flights per week combined, between the two cities.

British Airways chief executive, Sean Doyle, said: “We know people want to travel but our skies remain all but closed and the UK is being left behind. Major economies like Germany are adopting testing to replace quarantine.

“We need the UK government to introduce a system that allows travellers to take reliable, affordable tests before departure, so they are confident that fellow passengers are Covid-free.

“For people arriving from countries with high infection rates, a further test on arrival should then release them from quarantine.”
