How long after a breast lift until I can fly from New York to Florida?

That would be a decision that needs to be discussed with your surgeon ahead of time. It could be anywhere from
One to two weeks

I applaud your concern and awareness!
I usually ask my out of town patients to remain close to me for one to two weeks after surgery, depending on the procedure and distance to be traveled. Certain operations require closer monitoring for a longer period of time than others. I usually perform virtual consultation first and then, if the individual chooses me as their surgeon, I prefer to see them again the day before The planned surgical date.
Breast lift surgery usually only requires a one week stay here in New York, as this allows me to see the patient one or two days after surgery and then again right before they return home. The three hour flight back to Florida is relatively short and reasonable. I use all absorbable sutures, so suture removal is not an issue. Come see me virtually, or another board-certified plastic surgeon in New York City to explore all options for your particular breast lift surgery. Best of luck!
