They'll never do it, but I'd love to see SJC - IAD or DCA. It's bizarre to me that I can get to Tokyo and London from SJC, but not Washington DC. Maybe the business isn't there, or more likely, they bet people will drive up to SFO for a non-stop (sadly a good bet in my case). But if any carrier ever decides to offer a non stop San Jose - DC, I'll move the majority of my business to them / their partners straight away.
