Airport Shuttle Service, New Orleans
If you're on a tight schedule, or there's more than one of you, get a cab to and from the airport in New Orleans. I was the last to be dropped off on arrival on the shuttle, and on return was deposited at the airport over 2.5 hours before my flight. I had even rung to ask if a later shuttle was possible, to which the answer was a firm 'no'. Particularly galling as I could have spent another hour in the sun at the Crescent City blues festival instead of sitting outside Popeyes in New Orleans airport.
