Wow, right now the best route booking B fairs is looking like this @ 1535. that's the price of a coach international flight. Same flight booking best deals fare is half that. I'm not paying for the ticket but the price might not click with the company. Virgina America flight there non stop is about $600. Tough choice.

I've never flown across the country in F. Is the service/foods any difference?

Honestly, flying F between SJC to SEA in F isn't worth it IMO if it was on my dime.
