I'm doing my first UA mileage run this weekend. Pushing for 1K.

I generally avoid IAD like the plague, so I don't know much about it. How are the lines at check-in and security on a Saturday morning? I figure I'd probably check in between 6 and 7am. I won't be checking anything as both of my MRs are same day returns, so I'll just have my laptop with me.

Thanks,

Super
