We left Zihua 3 hours before scheduled departure today. Before checking in, one must stop at a health inspection station and fill out a short probative health questionnaire that only takes a few minutes to complete.
Most airport personnel were not wearing masks; neither were any of the flight crew. There were no special protocols @ LAX Immigration.
1 One should arrive at the airport, but 3 hrs. was too early;
2 Appreciate your flight staff. They are exposed to innumerable diseases in the course of their duties. Thet were children on our flight who looked like they had the chicken pox! It was not mosquito bites.
3 The flight attendant said that they were treating this like any regular course of flu.
p.s. Today was the Mexican Labor holiday; I don't know if "extends" over the weekend. Businesses and services may be closed.
