I got here on the 5th. I filled out the e-ticket on line for and the other medical info form. The attendant gave me 4 forms on the plane, which 2 is the same of the on line forms. I fill out all of them, and when I got to the airport (POP), they only took one small form from my pile of paper. No e-ticket was required. But I saw a sign with the QR code posted by the exit.
