You're due the same as all other elites for delayed baggage - $50/day up to 5 days for the purchase of incidentals and such. Why you were traveling or who you were meeting is irrelevant.

Also, did you ask about getting on the earlier flight while checking in or only after? If you knew the airport was closed for snow when you got there asking about moving up to the earlier flight then would be a good thing. That way they can tag your bags as being standby for the earlier flight before sending them through to screening. That would likely have worked much better for you.
