United Airlines has launched the world’s first free transatlantic Covid-19 testing pilot program between Newark Liberty International and London Heathrow.

From November 16 through December 11, the airline will offer rapid tests to every passenger over 2 years old, and crew members on board select flights from Newark Liberty Heathrow, free of charge.

Anyone who does not wish to be tested will be placed on another flight, guaranteeing everyone on board other than children under two will have tested negative before departure.

United will share customer feedback of this pilot with governments on both sides of the Atlantic to further demonstrate the effectiveness of these programs as an alternative to mandatory quarantines or duplicative travel restrictions. United has seen a positive impact on travel demand and significant increases in customer load factors and revenue when testing options are available.

“We believe the ability to provide fast, same-day Covid-19 testing will play a vital role in safely reopening travel around the world and navigating quarantines and travel restrictions, particularly to key international destinations like London,” says Toby Enqvist, chief customer officer for United. “Through this pilot program, we’ll guarantee that everyone onboard has tested negative for Covid-19, adding another element to our layered approach to safety. United will continue to lead on testing, while at the same time exploring new solutions that contribute to the safest travel experience possible.”

United will collaborate with Premise Health, who will administer the rapid testing pilot program for the EWR-LHR flight. The test will be given to passengers traveling on United Flight 14, departing at 7:15 p.m., Mondays, Wednesdays, and Fridays. Appointments for the test are required, and customers are advised to schedule their tests at least three hours before their flight. An on-site testing facility will be located at the Newark United Club near Gate C93.

Before the pandemic, United operated six daily flights between New York/Newark and London using a 767-300ER (76L), offering not only the most frequency among U.S. carriers but also the most business class and Premium Economy seats.
