We flew done to Florida to visit my parents for a week-went from LGA to RSW-same thing-lines, no social distancing-the folks who are flying are clearly comfortable with things now...some having been vaccinated probably helps.
I still see restaurants frantically wiping down chairs and tables-what a joke-that is pure theatre-it's an airborne virus-cleaning a chair does nothing. (however it is nice that things are being clearned vs not cleaned at all, but alot of this is simply theatre to make people feel more comfortablle.
