Mid-Atlantic - Getting to Lexington, VA?

Hey everyone, I'm looking to get to Lexington this upcoming weekend from SFO/SJC/OAK. I'm not sure if I'm hitting all of the airports in the area but I tried ROA, LYH and IAD/DCA. I'm seeing the lowest fare around $500.

Are there any other options I haven't used for that area? Any other suggestions on how to get there would be great as well.

Thanks from a west-coaster!

bwi is usually our least expensive airport. it is 50 more miles in the wrong direction.

You can look at CHO (Charlottesville) much closer than IAD/DCA. RIC (Richmond) as well.

PHF (Newport News) or ORF (Norfolk) are options too, but farther.
