Here’s a question: If airlines and/or cruise lines demand proof of immunization to board, will consumers comply...?
IMO the tourist industries will only do what they have to to be in compliance with federal requirements. Anything more is counter-business. A good example is the cruise line requirement for a not from a doctor that a person didn’t have any underlying health issue in order to board. Well, that didn’t last long when other cruise lines didn’t follow suit.
