The flight was from Munich to Hamburg, the airline said in a statement published Thursday. A second test flight is planned to take passengers from Hamburg to Munich.
"With our test strategy, we are pursuing the goal of using the data obtained to gain important insights into the use of rapid tests,” said Christina Foerster, Lufthansa Group Executive Board Member for Customer, IT & Corporate Responsibility.
“Successful testing of entire flights can be the key to revitalizing international air traffic.”
The rapid antigen tests do not detect the Covid-19 pathogen, but can detect proteins associated with it.
Lufthansa said that customers receive their test results within 30 to 60 minutes of being tested.
The airline said that only if the results are negative will a passenger's boarding pass be activated and access to the gate granted.
Passengers not wanting to be tested will be transferred to an alternative flight, the statement added.
