Sometimes that walk – more often, that dash – between gates for a connectintg flight feels like a mile. Or more.

But how long is that walk really? And what is the longest distance a passenger would have to walk to make a connection at a U.S. airport?

With the help of airport record keepers and my brand new collapsible distance wheel, I’m working on finding that out.

Want to help? Next time you’re at an airport and feel like getting some exercise, start your pedometer – or take out your collapsible distance wheel – and measure off the distance between the farthest gates in an airport.

No buses, no trams. Just walking. Let me know what you find out.
