Friends - does anyone have experience with getting a Covid test at the Barcelona airport? Is the testing site before or after security and passport control? Trying to figure out how many hours before the flight to book the appointment.

I’m flying back to the US the same day my cruise disembarks. So with luggage and etc, in airport testing seems like the best option. This is the vendor information: https://flycovidtestcenter.com/en/barcelona-t1/

thank you!
