I love Jet Blue and fly them whenever I get the chance. It feels like they have more legroom to me. Plus, you get Direct TV and XM/Sirius radio. Being able to watch that really makes the flight go by faster for me. Another bonus is that they come around with all sorts of snacks (chocolate chip cookies, animal crackers, some sort of Doritos mix, potato chips, and a few other things), as well as soft drinks. Oh, I forgot to add - you can check one bag for free.
The airport is on the east end of town. Which way are you planning on driving there? There always seems to be construction going on in Richmond, and with all of the potholes they have down there now, they're really working on a lot of roads. The big construction when they're shutting down lanes they tend to do at night, though, so you should be OK.
