In booking a March trip from MSN to SFO, I can fly via ORD or DEN. I'm wondering if a weather-related foul-up is less likely in DEN. I've lived in the Midwest and flown through ORD all my life, so I know what I'm dealing with there, but have no experience with DEN other than in summer.

Would appreciate any advice from those familiar with March DEN weather. Thanks!
