Breakdown of timing for my most recent flight (yesterday):
Travel time to airport: 90 minutes (normal time 20 minutes, but it was rush hour. A Taylor Swift concert on the way was not a problem.)
Time in airport, including ground hold time due to weather at destination: 210 minutes (normal 60 minutes)
Actual flight time: 70 minutes (normal time 50 minutes)
Time from touchdown to exiting the parking lot: 90 minutes (normal 30 minutes - airport operations stinks late at night)
Drive home: 90 minutes (normally 60 minutes, but weather and detours factored in).
Basically, 9 hr total travel time for a nominal 50 minute flight. Driving time is slightly shorter.
