As quoted in numerous stories in Florida papers today, March 24, 2020:
"Today there are over 190 direct flights from the New York City area to Florida,” [Gov. Ron] DeSantis said. “I would reckon given the outbreak there that every single flight has someone on it that is positive for COVID-19, and so as we’re working to stop it in the state of Florida.”
So, the number of flights at this time is significant, and has not yet been reduced by Covid19 concerns. Of course, the historic volume may be much higher at various times.
Annual Airport Passengers:
Miami: (2018) >45 million million passengers
Tampa (2020, previous 12 months:) 22,731,796 passengers
Orlando: (2019) >50 million passengers
Total: 117.7 million arriving and departing passengers a year
That's an average of 322,000 passengers a day for three airports in Florida, or 161,000 arrivals (if half are arrivals and half are departures).
The annual volume through Miami, Orlando, and Tampa is pretty big, so 19,000 to 38,000 people in one day from New York (190 flights with roughly 100 to 200 passengers each) is relatively small. Current estimates are that 1,000 people a day were moving to Florida before the Covid pandemic. The governor makes it sound like an invasion. In fact, it might be a slowdown.
