I have actually, several times.

I own a Brompton, which fits through the baggage X-ray and can be checked like a stroller at the gate. I've flown with it more than 12 times, and you had better believe I've ridden it in the terminal

I only do this during late arrivals when the airport is almost empty, travel at a reasonable speed, and otherwise conduct myself like a civilized human being. On a bike. In the airport. It's great actually.
