Now they're confusing me even more.

They invite me to upload my covid and entry documents.

So I'm transiting through FRA, to go to BCN.

So I upload a photo of my CDC card, the Spain QR code document and a PCR test result from a pharmacy, with sample taken 48 hours before the LH455 departure from SFO.

They return with, bad document, test is too old. Yeah over 48 hours but well within 72 hours for PCR.

Well I don't even need a test, either from Spain or Germany if on a US passport with a CDC card.

I'm already checked in through earlier actions.

Now I have to wonder if I should call LH on the morning before my afternoon departure, to sort this out. I may get an agent who isn't up on all the latest info about travel restrictions in Spain.
