Looking to complete the Dec. Juarada for tomorrow/06th. Its giving both the options.. That is one can opt for a 14 day quarantine or submit the PDF of the PCR.
I believe its the wisest thing they have done..giving a good possibility to end user.
I believe next step should be reduce quarantine to 10 days as many countries have already started.
You need a PCR (or a certificado showing you have had covid already) to be allowed to board the plane. The rule will be enforced as of tomorrow.
Don't try to deduce anything based on the DDJJ -- that declaration is done by someone with basic IT skills -- it's horrible, clunky and not intuitive. I just tried to fill it out of curiosity and for me it doesn't even allow me to attach a PCR, not sure how you managed to see that option.
