Hello all this is my 1st post here pleased to meet you!

My question is about the Covid Attestation form.

In my case i am fully vaccinated and am travelling with British Airways from UK to San Francisco
I have printed off the form ( I do not really want to use Verifly )

Does anyone know if this bit will mean i cannot use Online Check In when it opens? and/or will i have to queue up to show this form?

Thank you
