Leaving for Louisville

I've got an early flight booked for my trip to Kentucky. It's good in the sense that I'll arrive there at a decent hour, but it makes for less sleep prior to the flight out of Sacramento. I'll probably try to sleep about five hours before heading to the airport - so it shouldn't be too bad. I don't anticipate that I'll get much, if any, rest on the plane. There are too many travelers and not much time between flights. Southwest is a good airline, but you don't get a lot of space to stretch out and the noise level can be high - because of the crowded conditions. However, you can't really complain about their fares - they have some of the best rates of any airline.
