Sorry if this has been asked and answered elsewhere

I am off to Ponta Delgada tomorrow from LHR

Online check in potentially opens in 3 hours

I have had two emails from BA in the last 12 hours, instructing me to go to MMB, in order to upload the NHS covid vaccination certificate and or a covid test result.
If this is not done, online check-in will not be available

Portugal doesn't need these for entry, however I will of course be taking hard copies.

There is nowhere in MMB to upload any docs anyway.

Are these just blanket emails from BA, sent to everyone who is travelling, regardless of their destination or covid requirements and online check in would be open to me regardless?
