Two years ago, I flew to 5 airports on commercial airlines in a day. Due to bad weather condition, my flight was forced to land in two other airports(each with 1 or 2 hours stopover) before it finally landed at the destination airport. So I went to 4 airports on the same plane(Did get out of my plane to stretch my legs at the terminals). After a quick meeting, I went back home on the same night. That's 5 different airports in one day.

I am sure this is nothing compared to fellow FTs' experiences. Someone who is doing a roadshow must have visited a dozen airports in a day. Hope to hear more interesting stories from FTs.
