Arriving at SEA/TAC to fly back to San Francisco from NANOG 40, we find that there are two commercial WiFi providers, AT&T and T-Mobile.

So, Pete (on the left) connected to AT&T, shared the connection to his ethernet port which was connected to my MacBook via the red cable and my MacBook was sharing it back out on my WiFi interface so Matt (on the right) could connect. We were all happy campers.
Now if there is a way to do this without paying AT&T…
