I had a 45-minute connection this morning. Flight was supposed to leave Richmond at 6:10 AM and arrive in Memphis at 8:40, connecting to a flight leaving Memphis at 9:25 and arriving in Tampa at 12:10. (All times Central.) The flight didn't leave Richmond until 7:25. Needless to say, I missed the connection.
It looked for a while like I was going to go to Houston Intercontinental first, then Tampa, but a seat came open on a direct flight while they were trying to get my boarding passes printed. I'm now leaving Memphis at 1:45, arriving in Tampa at 4:32 PM Eastern. This will get in the way of getting my presentation updated and my handouts ready for my 6 PM session tomorrow, but it should be possible, at least.
This isn't the first time I've had trouble with a tight connection in Memphis, though it's the first time I've actually missed the flight. There have been a couple of times I've had to make connections in less than 15 minutes.
