Has anyone arrived from a "3rd Country" (i.e., not a Schengen area or EU member) in Madrid/MAD-Terminal 4 and transited to a connecting with a (in my case, Iberian) flight to Porto from Terminal 4S?
I am arriving from the US, and know that a QR code is needed to enter Spain. But with this being just a connection, will I need to go through the Spanish Ministry of Health procedure-getting the QR code? I understand that passengers need to clear customs and immigration (particularly I assume if this is your entry point into the EU) before boarding their connecting flight. Anyone have any links to information on this? Thank you.
