Walk to bus from plane is <5min, bus is every 5 minutes, ride is 8 minutes, walk from bus to security is <5min. BP/passport not required for security. IME, I was the only one going through security. Connections desk is after security. Continental has a sign up but I didn't see anyone (surely they were there?). It dumps you out near the low-numbered gates, which Continental uses about 75% of the time IME, although the ST lounge is at the other end. From plane to lounge was maybe 30-40min tops. If security was busy and you missed the next bus, etc, it could be maybe be an hour.

Accordingly, with a 2hr connection, if your flight is 30 minutes late and you hit worse conditions, you'll arrive during boarding. An hour late and you're probably hosed.
