Compass guys commuting out of IAD?
 

Is it possible to get IAD employee parking? If so how and where do I go?
Thanks

They used to allow it, but don't know about now. (I don't see why not since they moved employee parking to a bigger lot that's even farther away from the terminal and never full...)

Talk to MWAA. I'd start down in the SIDA office (I'm pretty sure they handle parking). It's located off of baggage claim on the transportation side of the building. Look for "ID Office" or something like that hanging from the ceiling.

Can't remember what MWAA charges commuters for parking, but I want to say it's $150-200/year. You might need a letter from JK or somebody at Compass verifying the fact that you need to commute from IAD to MSP. JK also might be able to direct you in the right direction about who to talk with since Compass has a handful of folks that were probably issued IAD parking badges for the CRJ operations.
