Also to add in. If you lived in BHM. Pinnacle has a flight that goes from MEM to BHM. There are a couple 727 flights that pass through BHM. If you think things are getting too close for comfort, the four hour drive is do-able. I know people that drive from southern Indiana, St. Louis, North Alabama, Nashville, etc... They'll always try to catch a flight but have an airport car there just in case.
I just saw what Albie said, Ditto.
