Qantas Airlines has announced that in order to board one of their flights in the future, every passenger MUST have been vaccinated against Covid19.  Word in the air (hahaha as opposed to word on the street....I amuse myself) is that several airlines plan to follow suit.  This really makes the world of anti-vaxers much smaller.    Do you think Cruise lines will enforce this as well?  If you want on board, you have to show proof of vaccination?
