We were on the NA Nov. 12 - 19. We wore our masks on the plane and in the airport, didn't go to the shows, tried to sit just at a table for 2 most meals and stayed away from people as much as possible. Coming home on the 19th, the Fort Lauderdale airport was jam packed with travellers, coughing, sneezing, etc. I don't think 5% of the people had masks on. We had our masks on, but 4 days after arriving home, I got the flu and I'm still sick. A woman sat down beside me at the airport and was obviously sick with something. I finally said to her, very nicely, that I had an extra mask if she would like it. She didn't and she got up and moved. I think I picked up something at the airport, not on the ship.
