Why don't the airlines set up bus service from IAD to downtown or maybe Crystal City? Seems like if the airlines themselves pushed that and ran it (versus third-parties like Wash Flyer or public transit) a lot more people would use it and see value of it. They could even do quasi-DCA connections with the bus like UA does for... is it SJC-SFO? I know there's a connecton out there on a bus. Seems like this would be a perfect thing for the US and/or DL Shuttle, for instance.

If DCA opens in a couple weeks, this would probably be too much effort. But it doesn't seem likely it will open that soon.
