I'll soon be attending an event in Boulder that's scheduled to end at 5 PM sharp. I'm connecting to a once-daily international flight from SFO, so my choices are to either:

1. Book an itinerary that departs from DEN at 6:55 PM, or
2. Stay an extra day in Boulder, fly out the next day, and arrive back home a day later

Given likely rush hour traffic (I'll Uber/Lyft), TSA security lines etc, is **option 1 feasible**? Checking in online, no bags, but also no special TSA status (Clear etc).

Note: There's also a later DEN-SFO flight that would get me there in time, but due to the vagaries of airline pricing it costs *$2000 more*, which I can't really justify -- an extra hotel night is way cheaper.
