I have a somewhat dicey separate-ticket connection tomorrow wherein I have just over 2 hours between arrival on AS in T2 and departure on AA in T3, with a checked bag. (What can I say, I like to live on the edge...)

Can anyone provide a map or other instructions on how to get between T2 and T3 landside? Should I use the people mover (and if so, how do I get to it from AS bag claim)? Alternatively, should I use the underground tunnel system? I can't seem to find much information on the layout and navigation of those tunnels online; if anyone can describe how to use it, I'd appreciate it!
