St. Pete-Clearwater International Airport (PIE) is celebrating Pi Day a day early this year by handing out free individual-sized strawberry and Key Lime pies on Friday, March 13 from 1:30 to 3:14 p.m.

Pie will be served both curbside (drive-by pie) and inside the terminal.

Why free pie?

The Greek letter “π” (Pi), is the symbol that represents the mathematical constant that is the ratio of the circumference of a circle to its diameter and has been calculated to over a trillion digits, the first of which are 3.14.

And, of course, free pie is a great way to celebrate PIE airport, which gets its identifier code from its original name, Pinellas International Airport.
