I am doing a 21 hour transit coming from RAK thru LIS and then on to EWR. I have the Swiss covid pass on my phone. It is confusing even looking at Sherpa. I think I need a test before getting on the plane in RAK and then I will need to get another test in LIS for my onward flight to the US. I will ask at the TAP desk in RAK when I arrive there from MAD to be sure what I think is correct is actually correct.
