Wrongly Denied Boarding to Spain at LHR
I am a fully vaccinated US citizen traveling from ORD to BCN with a layover at LHR. Spain recently opened to fully vaccinated tourists with few exceptions (e.g. Brazil, India).
I flew from ORD to LHR with no issues. At LHR, however, I was denied boarding to BCN despite having both the CDC card (our only proof of vaccination in the US) and the SpTH QR code.
The BA gate agent called the BA office overseeing entry requirements who said that the CDC card is not a valid vaccination certificate.
Spain accepts the CDC card as a valid vaccination certificate and I have not heard of anyone else running into this issue on other airlines (even Iberia).
I am currently waiting on the BA customer service desk to sort this out but they're running into the same issue with the abovementioned BA office...
