I'm not familiar with the MSP airport. I'll be making a connection there soon. Historically, the incoming flight comes into Concourse C and the outbound flight leaves from Concourse G.
I've looked at the airport web site and the 2 concourses appear to be connected by some sort of tunnel/bridge/something else. I've looked at Google maps and there appears to be parking lot between two terminals.
What is the fastest way to get between C and G?
