Travel to WVU from Northern CA (Oakland, SFO etc)

Hi my son was admitted to WVU in biomedical engineering. We are wanting to go visit soon but the travel from the Bay Area looks challenging. Anyone else done this and can recommend?

Most kids that need to fly go into Pittsburgh and then take a shuttle bus. I’m pretty sure there’s a direct flight or two from SFO on United to Pittsburgh as I took one to PIT 2 years ago.
